workshop // Othernet, Alternet, Darknet

Once more, thank you very much for inviting me to talk with you about “Other Networks” and give a workshop on “Othernet, Alternet, Darknet // the Past, Present, and Future of Alternate Networks.” In preparation for today’s workshop I suggested you read “Against the Frictionless Interface! An Interview with Lori Emerson” and “What’s Wrong With the Internet & How to Fix It: An Interview with John Day.”

Before I build on these readings with a more extensive discussion of TCP/IP, I would like to discuss what it currently means to be on the Internet for many people and then show you a couple tools that make it alarmingly clear the way in which profit and capital saturates every single one of our clicks online. To that end, I’d like you to download a couple revealing extensions to your Chrome browser and/or an add-on to your Firefox browser to clearly visualize what’s happening when you’re on the web ; I use both browsers so I encourage you to download both but it’s also fine if you just want to play with one

  • open up Firefox and install Lightbeam – an add-on that “shines a light on who’s watching you” by way of interactive visualizations that show you the first and third party sites you’re often unwittingly interacting with on the web
  • now open up Chrome and install Disconnect – a browser extension that stops major third parties from tracking the webpages you go to
  • have any of you used these tools before? anything revealing or surprising?

Now I’d like to talk about alternatives to the current structure of the Internet, beginning with a brief overview of how TCP/IP itself could have been different (picking up the interview with John Day), leading to a different present-day Internet, and then moving on to contemporary projects and platforms you might use to get off or disrupt the Internet. I will touch on the following:

  • how thinking about the past and present of networks could be a way to imagine the future of our connected lives
  • how excavating the knowledge/power structures underlying TCP/IP can denaturalize that monolith “the Internet” and help us think about how the Internet could be otherwise. In particular, I discussed:
    • how TCP/IP was created to benefit the free market, not necessarily to exemplify democratic ideals of freedom and openness
    • the result of intense, complex political wrangling between communities of engineers, industry workers, and representatives who were almost uniformly white, middle class men often from the same school or neighborhood
    • how the protocol is based on concepts of blackboxing and layering taken from the design of operating systems rather than networks
    • how there were and still are alternatives to TCP/IP such as RINA that could potentially make the Internet work better than it currently does

With this groundwork, I would like to use the rest of the workshop to think as expansively, broadly, and imaginatively about what an alternative Internet might look like – one that we built ourselves, imagining for the moment that we can build whatever structure we dream up.  Here, then, are some contemporary examples of Other Networks I would like you to explore and/or experiment with:

  • Netless, created by Danja Vasiliev
  • Alternet, created by Sarah T. Gold
  • Firechat, created by Open Garden
    • create an account, see if you can find the #OtherNetworks chatroom I created, and start talking to each other
  • PirateBox, created by David Darts
    • if there’s time, I will demo a PirateBox I built to prove to you that even the most inept Internet user can do it
  • Tor, created by the United States Naval Research Laboratory and DARPA
    • read my notes and warnings below, download Tor, and try accessing the links I include below

Because Tor has become synonymous with criminal activity, for the sake of educating you, here is a bit more on what Tor is and why you might like to use it. Tor is primarily a privacy network that allows you to access the surface Internet without being tracked; it also allows you to access the deep web/darknet – any site or material that’s on the Internet but not indexed by search engines; keep in mind that most of the deep web/darknet is dedicated to innocent forums, blogs, essays and so on; because of the protection it offers, the darknet is attractive to activists in oppressive regimes as well as government agencies.

Why use Tor? While the Tor browser will work much slower than Chrome or Firefox, if you value privacy or if you would like to find a way to circumvent the online tracking we discussed earlier, you might like to give it a try. You might also give it a try if you would like to become a more informed, more active Internet user.

Some warnings:

    • not surprisingly, Tor does not guarantee perfect anonymity; if you don’t use a Virtual Private Network in addition to Tor, people can still see you’re using Tor even if they can’t necessarily see what sites you’re visiting; hopefully it goes without saying that you shouldn’t use a university VPN – instead consider purchasing the very inexpensive IPVanish and take a look at tips here and here to understand better how VPN works with Tor
    • don’t Torrent over Tor and especially don’t use BitTorrent and Tor together
    • according to the Tor website, avoid opening  .doc and .pdf documents while on Tor as there seems to be a way to reveal your IP address once you do this
    • try to use HTTPS versions of websites; Tor encrypts your traffic to and within the Tor network but to ensure encryption at your final destination, try to also use the HTTPS Everywhere extension
    • to make sure you’re not tracked down if you inadvertently visit a website that’s criminal in nature, turn off scripts and plugins in the Tor options (according to their website, you do this by clicking the button just before the address bar).
    • be very cautious about clicking on links on Tor – try to only use known directories to reach authenticated destinations.

Here are a very few safe Tor links that have worked for me:

  • search engine TORCH at http://xmh57jrzrnw6insl.onion/
  • search engine DuckDuckGo at http://3g2upl4pq6kufc4m.onion/
  • the first issue of a Tor-hosted literary journal, The Torist (pdf) at http://toristinkirir4xj.onion/issue1.pdf
  • and, surprisingly, Facebook! at https://www.facebookcorewwwi.onion

If you’d like to continue thinking about these issues post-workshop, one place to start is to think about the repercussions of the underlying structure of the Internet – especially in the context of how the structure might create a certain power dynamic that excludes (women, minorities, underprivileged communities, those who are less technically savvy) more than it includes. Questions I’ll leave you with:

  • What does a cooperatively owned Internet look like and why might we want one? If you need help getting started, consider checking out Platform Cooperativism.
  • What does a non-profit, non-commercial network look like?
  • What does a feminist network look like? Can the Internet be feminist? These 15 “Feminist Principles of the Feminist Internet” might help you get started.  You might also like to look at this interview with Jac sm Kee who has been deeply involved in the Association for Progressive Communication’s (APC) Women’s Rights Programme; Kee states that “to start, a feminist Internet is one where everyone has universal, equal and meaningful access to an open and transformative Internet to enable the exercise of all of our rights, to play, to create, to form communities, to organize for change, in freedom and pleasure.”

selling the future at the MIT Media Lab

The following is the text of a talk I gave at Transmediale on February 5, 2016 as part of a panel with Jussi Parikka, Ryan Bishop, and John Beck on “The Persistence of the Lab.” The text of the talk will eventually find its way into THE LAB BOOK.

*

What follows are some of my initial findings as I’ve been researching the past and present of the MIT Media Lab – a lab founded in 1985 by former MIT President Jerome Wiesner and Nicholas Negroponte of OLPC fame and then directed by Negroponte for the first twenty years of its existence so far. The Media Lab has become synonymous with “inventing the future,” partly because of a dogged thirty year long marketing campaign whose success we can measure by the fact that almost any discussion of “the future” of technology is a discussion about some project at the Media Lab.

And of course the lab has also become synonymous with “inventing the future” because of the central role it’s historically played in the fields of wireless networks, field sensing, web browsers, the WWW, and the central role the lab is now playing in neurobiology, biologically inspired fabrication, socially adaptive robots, emotive computing, and the list goes on and on. Given this list, you’d be right to think that the lab has long been driven by an insatiable thirst for profit operating under the guise of an innocent desire to just keep performing computerized feats of near impossibility, decade after decade.

But I’ve also come to see this performance is partly a product of a post-Sputnik Cold War race to out-do the Soviets no matter what the reality, the project or the cost. In Stewart Brand’s The Media Lab, the only book written so far exclusively on the media lab, written in 1986, the year after the lab opened, he writes with an astuteness I don’t usually associate with him:

If you wanted to push world-scale technology at a fever pace, what would you need to set it in motion and maintain it indefinitely? Not a hot war, because of the industrial destruction and the possibility of an outcome. You’d prefer a cold war, ideally between two empires that had won a hot war. You wouldn’t mind if one were fabulously paranoid from being traumatized by the most massive surprise attack in history (as the USSR was by Hitler’s Barbarossa) or if the other was fabulously wealthy, accelerated by the war but undamaged by it (as the US was by victory in Europe and the Pacific). Set them an ocean apart. Stand back and marvel. (161-162)

Brand then goes on to explain how American computer science owes so much to the Soviet space program – one which resulted in the creation of Eisenhower’s Advanced Research Projects Agency which, by the 1970s, had an annual budget of $238 million and funded many labs at MIT. And even when ARPA changed to DARPA to show that all agency projects had direct defense applicability, it still continued to fund labs such as the predecessor to the Media Lab, Nicholas Negroponte’s Architecture Machine Group. Still to this day, even though the Media Lab is famous for its corporate sponsorship, the U.S. Army is listed as one of its sponsors and many of the lab’s projects still do have direct applicability in a defense context.

But the lab is also the product of MIT’s long history of pushing the boundaries of what’s acceptable in higher education in terms of its deep ties with the military industrial complex and corporate sponsorship that goes back even to the 1920s. However, we now know that even though MIT tried to work with corporate partners in the post World War I years as it tried to pay for research programs in chemical and electrical engineering, the depression put an end to corporate partnerships until late in the second world war. The WWII in fact became a decisive turning point in the history of university science/tech labs, likely because of the enormous amount of funds that were suddenly available to sponsor research and development contracts.

Historian Stuart Leslie reports that during the war years MIT alone received $117 million in R&D contracts. So, again, naturally, once the “hot war” was over in 1945, it was almost as if MIT needed a Cold War as much as the state did so that it would continue to receive hundreds of millions of dollars’ worth of contracts. As a result, by the 1960s, physicist Alan Weinberg famously said that it was getting increasingly hard “to tell whether MIT is a university with many government research laboratories appended to it or a cluster of government research laboratories with a very good educational institution attached to it.” (quoted in Leslie 14)

Also in the 1960s, the Research Lab of Electronics (or RLE) in particular was getting the lion’s share of the funding. RLE was a lab created in 1946 as a continuation of the world war II era Radiation Lab which was responsible for designing almost half of the radar deployed during the war. The RLE also became the template for many MIT labs that followed – particularly the Arch Mach Group which, again, turned into the Media Lab in the mid 80s. RLE was one of the first labs to be thoroughly interdisciplinary, to train grad students who went on to write the books that future grad students read and then responded to by writing other books or who went on to fund tech companies, and it also groomed future leaders either of the lab itself, the university, or for government/industry. Given this beautifully efficient system of using labs to both create and replicate knowledge, it makes perfect sense that researchers Vannevar Bush and Norbert Weiner – famous in part for their roles in advancing war-time technology – were teachers at MIT of Julius Stratton, the founding Director of RLE, and Jerome Wiesner who, again, you remember later co-founded the Media Lab.

Wiesner’s life in corporate and government sponsored labs began in 1940 as he was appointed chief engineer for the Acoustical and Record Laboratory of the Library of Congress. His job at the time mostly involved traveling to the South/Southwest under a Carnegie Corporation grant, with folklorist Alan Lomax, recording the folk music of these areas. Two years later, in 1942, Wiesner joined the RadLab at MIT and soon moved to the lab’s advisory committee; during his time there he was largely responsible for Project Cadillac which worked on the predecessor to the airborne early warning and control system. After World War II, the RadLab was dismantled in 1946 and in its place the RLE was created with Wiesner as the assistant and then associate director and then director from 1947 to to 1961. 1961 was the same year President John F. Kennedy named Wiesner to chair the President’s Science Advisory Committee; Weisner served Kennedy until Kennedy’s death in 1963 and then served President Johnson for one more year and most of his work involved advising the presidents on the space race and on nuclear disarmament. In 1966 Wiesner moved back to MIT as university provost and then President from ’71-’80. With Nicholas Negroponte at his side, he started fundraising for the lab in 1977 while he was president and, again, became co-founder of the lab in 1985 once he had stepped down as president and returned to life as a professor.

The foregoing is my brief history of one side of the Media Lab’s lineage that extends quite far back into the military-industrial complex, and especially the years of the Cold war, by way of Jerome Wiesner. Now I will move on to discuss the corporate, anti-intellectual lineage operating under the guise of “humanism” that runs through Nicholas Negroponte. The son of a Greek shipping magnate, Negroponte was educated in a series of private schools in New York, Switzerland and Connecticut and he completed his education with a MA in Architecture at MIT in the 1960s. You might also be interested to know that his older brother John Negroponte was a deputy secretary of state and the first ever Director of National Intelligence. In 1966, the year Wiesner returned to MIT to become provost, Nicholas became a faculty member there and a year later founded the Architecture Machine Group – a group which took a systems theory approach to studying the relationship between humans and machines. While the Media Lab’s lineage on Wiesner’s side runs through the Research Lab in Electronics and, earlier, the Radiation Lab, on Negroponte’s side the lineage runs through the Architecture Machine Group – a lab which combined the notion of a government sponsored lab with a 1960s-1970s-appropriate espoused dedication to humanism meshed with futurism.

But of course, especially as this particular brand of humanism is always tied to an imaginary future, it’s a particular kind of inhuman humanism that’s began in the Arch Mach group and went on to flourish in the Media lab – it’s one that constantly invokes an imagined future human that doesn’t really exist partly because it’s part of an ever-receding future but also because this imagined future human is only ever a privileged, highly individualized, boundary-policing, disembodied, white, western male human. I think you can see the essence of the Negroponte side of the Media Lab in three projects I want to touch on for the rest of my talk today. The first, from the early years of the Arch Mac group, was unglamorously called the “Hessdorfer Experiment” and is glowingly described by Negroponte in a section titled “Humanism Through Intelligent Machines” in The Architecture Machine, written in 1969 and published in 1970.

In the opening pages of the book, Negroponte mostly lays out the need for “humanistic” machines that respond to users’ environments, analyze user behavior, and even anticipate possible future problems and solutions – what he calls a machine that does not so much “problem solve” as it “problem worries.” (7) His example of what such an adaptive, responsive machine could look like is drawn from an experiment that undergraduate Richard Hessdorfer undertook in the lab the year the book was writen. Writes Negroponte, “Richard Hessdorfer is…constructing a machine conversationalist… The machine tries to build a model of the user’s English and through this model build another model, one of his needs and desires. It is a consumer item…that might someday be able to talk to citizens via touch-tone picture phone, or interactive cable television.” (56)

To help him build this machine conversationalist, Hessdorfer thought it would be useful to bring teletypewriting devices into a neighborhood in the south side of Boston – what Negroponte calls “Boston’s ghetto area.”

Negroponte writes:

THREE INHABITANTS OF THE NEIGHBORHOOD WERE ASKED TO CONVERSE WITH THIS MACHINE ABOUT THEIR LOCAL ENVIRONMENT. THOUGH THE CONVERSATION WAS HAMPERED BY THE NECESSITY OF TYPING ENGLISH SENTENCES, THE CHAT WAS SMOOTH ENOUGH TO REVEAL TWO IMPORTANT RESULTS. FIRST, THE THREE RESIDENTS HAD NO QUALMS OR SUSPICIONS ABOUT TALKING WITH A MACHINE IN ENGLISH, ABOUT PERSONAL DESIRES; THEY DID NOT TYPE UNCALLED-FOR REMARKS; INSTEAD, THEY IMMEDIATELY ENTERED A DISCOURSE ABOUT SLUM LANDLORDS, HIGHWAYS, SCHOOLS, AND THE LIKE. SECOND, THE THREE USER-INHABITANTS SAID THINGS TO THIS MACHINE THEY WOULD PROBABLY NOT HAVE SAID TO ANOTHER HUMAN, PARTICULARLY A WHITE PLANNER OR POLITICIAN: TO THEM THE MACHINE WAS NOT BLACK, WAS NOT WHITE, AND SURELY HAD NO PREJUDICES. (56-57)

I barely know where to begin with this passage except to say that the entire racist, deceptive undertaking is, for me, about as far away from a humanism that acknowledges the lives of these particular humans as you can get. It also clearly demonstrates what can happen when we believe so completely in the neutrality of the machine as its assumed neutrality – or its assumed capacity to give us pure, unmediated access to reality – can be called on as a magical mechanical solution to any human problems. Got a race problem? Get a computer!

The second project from about a year later, also run through the Architecture Machine Group, is just as disturbing. This time the subjects in the experiment are not African Americans but, rather, gerbils.

sellingTheFutureImages_Page_2

The experiment, called “SEEK,” was exhibited as part of the 1970 show at the New York Jewish Museum called SOFTWARE. It consisted of a computer-controlled environment, contained by Plexiglass and full of small blocks and gerbils who were there to change the position of the blocks following an automatic arrangement of the blocks by a robotic arm. The machine was supposed to analyze the gerbils’ actions and then try to successfully complete the rearrangement according to what the machine thought the gerbils were trying to do. Unfortunately, the experiment was a disaster.

sellingTheFutureImages_Page_3

As Orit Halpern puts it, “The exhibition’s computers rarely functioned…the museum almost went bankrupt; and in what might be seen as an omen, the experiment’s gerbils confused the computer, wrought havoc on the blocks, turned on each other in aggression, and wound up sick. No one thought to ask, or could ask, whether gerbils wish to live in a block built micro-world.” Again, this brand of humanism that’s in the name of the future is one that has very little to do with situatedness (or what’s now called posthumanism) – instead it has everything to do with abstraction and transcendence in the name of producing consumer products or R&D for the military-industrial complex.

The last example I’d like to touch on today is the One Laptop Per Child Project which Negroponte took up as an explicitly Media Lab project in the early 2000s and which, again, continues these same themes of humanism meshed with futurism combined with an espoused belief in the neutrality of the machine.

sellingTheFutureImages_Page_4

The difference now is that even just the guise of academic rigor and a scientific care for method that you could see in the Architecture Machine Group has been transformed, probably because of the lab’s responsibility toward its 80+ corporate sponsors, into the gleeful, continuous production of tech demonstrations, driven by the lab’s other, more ominous motto “DEMO OR DIE.”

OLPC was launched by Negroponte in 2005 and was effectively shut down in 2014. After traveling the world since at least the early 1980s to effectively sell personal computers to developing nations, Negroponte announced he had created a non-profit organization to produce a $100 laptop “at scale” – in other words, the cost of the laptop could only be this low in the early 2000s if, according to Negroponte, they could amass orders for 7-10 million laptops. Essentially, despite his often repeated statement that OLPC is not a laptop project but rather an education project, the essence of the project was still the same as the Hessdorfer experiment or “SEEK”: got a poveryty problem? get a computer! Worse yet, don’t do a study of whether what the community or nation needs are – JUST GET A COMPUTER.

Here’s what Negroponte said in a Ted Talk from 2006, suggesting that even if families didn’t use the laptops, they could use them as light sources:

I WAS RECENTLY IN A VILLAGE IN CAMBODIA – IN A VILLAGE THAT HAS NO ELECTRICITY, NO WATER, NO TELEVISION, NO PHONE. BUT IT NOW HAS BROADBAND INTERNET AND THESE KIDS – THEIR FIRST WORD IS “GOOGLE” AND THEY ONLY KNOW “SKYPE,” NOT TELEPHONY…AND THEY HAVE A BROADBAND CONNECTION IN A HUT WITH NO ELECTRICITY AND THEIR PARENTS LOVE THE COMPUTERS BECAUSE THEY’RE THE BRIGHTEST LIGHT SOURCE IN THE HOUSE. THIS LAPTOP PROJECT IS NOT SOMETHING YOU HAVE TO TEST. THE DAYS OF PILOT PROJECTS ARE OVER. WHEN PEOPLE SAY WELL WE’D LIKE TO DO 3 OR 4 THOUSAND IN OUR COUNTRY TO SEE HOW IT WORKS, SCREW YOU. GO TO THE BACK OF THE LINE AND SOMEONE ELSE WILL DO IT AND THEN WHEN YOU FIGURE OUT THIS WORKS YOU CAN JOIN AS WELL.

Not surprisingly, as with the lack of forethought in the experiment with the poor gerbils, by 2012 studies were coming out clearly indicating that the laptops – whether they were used in Peru, Nepal or Australia, made no measurable difference in reading and math test scores. In fact, one starts to get the sense that Negroponte’s truly remarkable skill which he began honing in the late 60s in the Architecture Machine Group is not design, not architecture, not tech per se, but rather dazzling salesmanship built on a lifetime pitching humanism and futurism via technological marvels. Even Stewart Brand saw this in Negroponte. Quoting Nat Rochester, a senior computer scientist and negotiator for IBM, “[If Nicholas] were an IBM salesman, he’d be a member of the Golden Circle…if you know what good salesmanship is, you can’t miss it when you get to know him.” (6)

And with this, the pitch perfect ending to this strange story is that in 2013, after selling millions of laptops to developing nations around the world, laptops that again made no measurable improvement in anyone’s lives, Negroponte left OLPC and went on to chair the Global Literacy X Prize as part of the XPRIZE Foundation. However, the prize itself no longer seems to exist and there’s no record of him being with the organization just a year later in 2014 – it seems he’s finally, quietly living out his salesman years back at MIT where he began.

XPRIZE, however, does exist and appears to be the ultimate nonprofit based on nothing more than air and yet more humanist slogans:

XPRIZE IS AN INNOVATION ENGINE. A FACILITATOR OF EXPONENTIAL CHANGE. A CATALYST FOR THE BENEFIT OF HUMANITY. WE BELIEVE IN THE POWER OF COMPETITION. THAT IT’S PART OF OUR DNA. OF HUMANITY ITSELF. THAT TAPPING INTO THAT INDOMITABLE SPIRIT OF COMPETITION BRINGS ABOUT BREAKTHROUGHS AND SOLUTIONS THAT ONCE SEEMED UNIMAGINABLE. IMPOSSIBLE. WE BELIEVE THAT YOU GET WHAT YOU INCENTIVIZE…RATHER THAN THROW MONEY AT A PROBLEM, WE INCENTIVIZE THE SOLUTION AND CHALLENGE THE WORLD TO SOLVE IT…WE BELIEVE THAT SOLUTIONS CAN COME FROM ANYONE, ANYWHERE AND THAT SOME OF THE GREATEST MINDS OF OUR TIME REMAIN UNTAPPED, READY TO BE ENGAGED BY A WORLD THAT IS IN DESPERATE NEED OF HELP. SOLUTIONS. CHANGE. AND RADICAL BREAKTHROUGHS FOR THE BENEFIT OF HUMANITY. CALL US CRAZY, BUT WE BELIEVE.

In many ways, XPRIZE is the ultimate Media Lab project spanning the world and whose board includes every major corporate executive you can think of – all to produce not even things anymore but rather just “incentives.” And in terms of the lab itself, while Negroponte seems to be practically retired and Wiesner passed away a number of years ago, the media lab continues to merrily churn out demos and products for consumers and the military under the leadership of Joi Ito – a venture capitalist with no completed degrees, a godson of Timothy Leary and a self-proclaimed “activist,” MIT couldn’t have found a better successor for the world-class salesman Nicholas Negroponte.

sister labs // Signal Lab & Media Archaeological Fundus

For years now, I’ve been yearning to go to Berlin to visit two labs that have the closest kinship to my own Media Archaeology Lab: the Signal Lab, run by Stefan Höltgen, and the Media Archaeological Fundus, founded by Wolfgang Ernst and now also run by Stefan. I finally got my chance to tour both labs in early February of this year, partly for pure pleasure and partly as a way to begin research for THE LAB BOOK: Situated Practices in Media Studies that Darren Wershler, Jussi Parikka and I are writing for the University of Minnesota Press.

While I’ve had some email correspondence with both Stefan and Wolfgang over the years about our labs, I didn’t realize how closely aligned our labs were until this visit. All three labs, including the MAL, are driven not by a nostalgic impulse or a desire to act as mini museums. Instead, we have all appropriated the science-based infrastructure of the lab for (anti) humanistic ends as we perform hands-on experiments with functioning media from the 19th and 20th centuries as a way to discover what Ernst has called the “time criticality” of each device.

There are, however, a few key differences between our labs – first, the MAL does have some preservationist responsibilities that the Signal Lab and the Fundus do not have; for example, we have hardware and software that has been donated to us by individuals hoping we will care for, maintain, and preserve their donations for as long as possible; we also have conventionally valuable hardware such as the machines that ran The Thing BBS and valuable digital literature and art from the 1980s such as Paul Zelevansky’s “SWALLOWS” and bpNichol’s “First Screening.” These preservationalist responsibilities mean the MAL has a more expansive, complex, and perhaps even conflicted mission as its belief in making the lab a space of hands-on experimentation and inquiry is bound to eventually conflict with our responsibility to protect certain particularly valuable holdings. By contrast, Stefan writes me in an email that “Indeed there are no such responsibilities for both of our collections. Vice versa we have a ‘hands-on imperative’ which is the opposite of materialistic preservation for the idea of preserving the knowledge within the apparatuses (that therefor often have to be damaged). We say that to all of our donators so they can decide if they want donate their stuff.”

The other major difference is in how we’ve structured our labs. Perhaps precisely because of the slight difference in our mission, the MAL’s holdings are mostly displayed on desks lining the walls; each machine  has its own desk and its own chair. The benefit to such an arrangement is it facilitates immediate and extended access – visitors often feel comfortable immediately sitting down, turning on the machines, and inserting a floppy disk or a cartridge sitting nearby. The drawback to this arrangement is partly that we’ve found ourselves very limited in the number of machines we can display and partly that there is still something auratic about this method of display – if the machines aren’t on when visitors arrive or without a tour guide on hand to continually remind visitors to play, tinker, hack, the pernicious assumption is that the MAL is a museum and one may only view the media on display as if they’re valuable works of art.

By contrast, both the Signal Lab and the Fundus structure their space by having machines stacked on shelves around the perimeter of the room with empty tables situated in the middle of the room such that visitors can remove machines from the shelves and use the tables for hands-on experiments. This is, I think, a small but fundamental difference in our labs as the infrastructure of these two Berlin labs is such that there is a firmer, even unapologetic rejection of the aura of the museum and an emphasis on serious research. As Stefan wrote to me in the same email: “Yes, it’s a question of space and the numbers of items stored in the collections. But the ‘Fundus’ also wants to be a fund (like that in theaters) where the students and researchers take items from the shelf to use in their projects. The fundus itself is not an exhibition. The Signal Lab has some workstation desks but most of the computers are stored in shelfs. The benefit is that the users have to build the systems with its peripherals for themselfs to use them (which – I think – is a form of technological praxis that has to be ‘preserved’ as well).”

Below are pictures I took on my cell phone of both labs – I hope you enjoy the virtual tour. And, finally, I would like to thank Stefan one more time for giving us such a wonderful tour of both labs.

media archaeology is literary studies

Katie Price and the good folks at Jacket2 Magazine requested short answers to a quick question on how media archaeology informs literary studies. Along with great responses by Aaron Angello, Jussi Parikka and Jane Birkin, I contributed the following paragraph:

If you believe that media archaeology largely coalesces in the writing of Friedrich Kittler, then media archaeology wouldn’t exist without literary studies! As others before me have pointed out, in many ways Kittler’s Discourse Networks works because of all the literary examples he relies on to make his argument – examples of how, after 1900, literature registers what he calls “a histrionics of media.” While he does also write that 1900 equally marks the disintegration of poetry, I’ve always thought what he really means is that this point marks the disintegration both of what had, up to that point, appeared to be the necessity of creating lyric, expressive poetry and of poetry as an art form that depends on creating the seamless, naturalized illusion of the human as separate from, above and beyond, the technological world. So, of course people continue to read and write lyric poetry all over the world after 1900; but now the poetry world is augmented with pieces that are non-semantic gurgles, grinds, glitches, eruptions, shrieks, howls, and so on – pieces that register the media effects of their time (I’m thinking of the Dadaists’ and Futurists’ visual and sound poems or dirty concrete poetry by Steve McCaffery or bpNichol’s and John Riddell’s experiments with the photocopier).

So while I do use the Media Archaeology Lab to work through a version of media archaeology that concerns itself with excavating failed media or dead ends in the history of technology, I am equally fascinated with what I’ve been calling “media poetics,” or poetry that registers media effects and that does not necessarily demand hermeneutic interpretation. For me, media archaeology’s most significant contribution to literary studies is the way it frees us from constantly, and only, interpreting content and allows us to go back and re-see poetry from the 20th and 21st centuries as inscriptions that record experiments with the limits and possibilities of writing media.

grad seminar + book project: theory & practice of doing, from DH to PH

At the same time as I keep working on “Other Networks” (a history of telecommunications networks that existed before or outside of the Internet), I’m pleased to announce I’ve also started working on another multi-part project – a graduate seminar and a book project – that has everything to do with the thinking and doing I’ve done over the last five years on the Media Archaeology Lab, on why I founded it in the first place, what discourses and practices I hope it intervenes in, and on what I hope it will become. While I’ve given probably twenty talks around the world on the lab and written a handful of short pieces on it, until now I haven’t had the chance to fully theorize the lab’s philosophy as well as its place in relation to other arts/humanities media labs as well as Digital Humanities labs.

To that end, starting this week, I am teaching a graduate seminar called “Theory & Practice of Doing // From the Digital Humanities to the Posthumanities.” Our course begins with a classic text, C.P. Snow’s The Two Cultures from 1959, to make clear the longstanding, perceived gulf between the sciences and the humanities and the resulting anxiety the humanities have had about how to advocate for their worth. Jump ahead fifty years and suddenly we’re in the midst of he digital humanities as well as various other media studies practices that have made their home in the humanities. Now, the anxieties are perhaps more about the displacement of traditional humanities work, not by the sciences but by a new humanities that’s inflected by scientific practice and, at times, a “spirit” of entrepreneurialism that’s particularly associated with the tech/startup world. We then move from Snow’s text to an overview of the state of the profession in the 21st century, focusing specifically on the ramifications of doing collaborative, interdisciplinary, project-based, hands-on work that engages with or relies on digital media in the humanities. This first part of the course then gives way to the second part, in which we explore more deeply a series of interconnected questions. What does it mean when humanists start placing “doing” at the center of their research agendas? What does it mean to do hands-on work in a digital humanities lab versus a media archaeology lab or a makerspace or a hackerspace? Are these scholars or practitioners appropriating the trappings of scientific labs for the sake of cultural capital or are they in a unique position to critique not only the way labs are often hierarchical, closed structures built around single individuals but also the way the data generated by these labs is too often seen as neutral or necessarily, timelessly true? Can 21st century hands-on work actually work not only to finally close the divide between “the two cultures”, science and humanities, but can it also work to displace the longstanding anthropocentrism at the heart of the humanities? You can see our schedule of weekly readings here.

The second project I’ve started working on with my esteemed colleagues Jussi Parikka and Darren Wershler is a collaboratively written book called THE LAB BOOK: Situated Practices and accompanying website (we haven’t launched it yet but the url will be whatisamedialab.com). In the book, we will provide a critical genealogy of the notion of the media and humanities lab as well as an exploration of some of the affordances labs can offer for the humanities – or the posthumanities – in the 21st century. The project offers a more detailed account of the media lab’s potential to open up new possibilities for thought and action in the present. Besides discussing Digital Humanities, we draw extensively on our own areas of expertise. Sections of the project will focus on sites such as the Berlin Humboldt University Media Archaeological Fundus, and my own Media Archaeology Lab. Other sections will describe the history of the Canadian Film Centre (CFC) Media Lab, the first of its kind in Canada. CFC Media Lab survived until the exact moment that universities started to duplicate it. Since CFC could not grant degrees, it promptly became a startup incubator program so it would produce more revenue than the constant stream of professional artists that were its traditional constituency. This history demonstrates once again the imbrication of creativity, innovation and monetization in the realm of media labs; it also offers an alternative way to investigate what a lab could mean as a cross-section of work in education, theory and critical practice.

While the book will thoroughly document and explicate this significant cultural force, the website will deliver a synchronic overview of contemporary media labs, mostly via interviews. If you take a look at the syllabus for the graduate seminar, you’ll see that graduate students will participate in interviewing people who have played or are playing a significant role in arts/humanities labs and we’ll post these interviews on whatisamedialab.com. Not only is the first time I’ve written a book with two other scholars, but this is also the first time I’ve had the chance to invite students to participate directly in a scholarly project.

I’m looking forward to posting links to interviews as well as updates on the book and website.

What’s Wrong With the Internet and How We Can Fix It: Interview With Internet Pioneer John Day

I appreciate very much the willingness of the editors at Ctrl-Z: New Media Philosophy to publish an updated, revised version of an interview I conducted with the computer scientist and Internet pioneer John Day via email. The published version is available at the link above and the original version is below.

The interview came about as a result of a chapter I’ve been working on for my “Other Networks” project, called “The Net Has Never Been Neutral.” In this piece, I try to expand the materialist bent of media archaeology, with its investment in hardware and software, to networks. Specifically, I’m working through the importance of understanding the technical specs of the Internet to figure out how we are unwittingly living out the legacy of the power/knowledge structures that produced TCP/IP. I also think through how the Internet could have been and may still be utterly different. In the course of researching that piece, I ran across fascinating work by Day in which he argues that “the Internet is an unfinished demo” and that we have become blind not only to its flaws but also to how and why it works the way it works. Below you’ll see Day expand specifically on five flaws of the TCP /IP model that are still entrenched in our contemporary Internet architecture and, even more fascinating, the ways in which a more sensible structure (like the one proposed by the French CYCLADES group) to handle network congestion would have made the issue of net neutrality beside the point. I hope you enjoy and many, many thanks to John for taking the time to correspond with me.

Emerson: You’ve written quite vigorously about the flaws of the TCP/IP model that go all the way back to the 1970s and about how our contemporary Internet is living out the legacy of those flaws. Particularly, you’ve pointed out repeatedly over the years how the problems with TCP were carried over not from the American ARPANET but from an attempt to create a transport protocol that was different from the one proposed by the French Cyclades group. First, could you explain to readers what Cyclades did that TCP should have done?

Day: There were several fundamental properties of networks the CYCLADES crew understood that the Internet group missed:

  • The Nature of Layers,
  • Why the Layers they had were there,
  • A complete naming and addressing model,
  • The fundamental conditions for synchronization,
  • That congestion could occur in networks, and
  • A raft of other missteps most of which follow from the previous 5, but some are unique.

First and probably foremost was the concept of layers. Computer Scientists use “layers” to structure and organize complex pieces of software. Think of a layer as a black box that does something, but the internal mechanism is hidden from the user of the box. One example is a black box that calculates the 24 hour weather forecast. We put in a bunch of data about temperature, pressure and wind speed and out pops a 24 hour weather forecast. We don’t have to understand how the blackbox did it. We don’t have to interact with all the different aspects it went through to do that. The black box hides the complexity so we can concentrate on other complicated problems for which the output of the black box is input. The operating system of your laptop is a black box. It does incredibly complex things but you don’t see what it is doing. Similarly, the layers of a network are organized that way. For the ARPANET group, BBN [Bolt, Barenek, and Newman] built the network and everyone else was responsible for the hosts. To the people responsible for the hosts, the network of IMPs was a blackbox that delivered packets. Consequently, for the problems they needed to solve, their concept of layers focused on the black boxes in the hosts. So the Internet’s concept of layers was focused on the layer in the Hosts where its primary purpose was modularity. The layers in the ARPANET hosts were the Physical Layer, the wire; IMP-HOST Protocol; the NCP; and the applications, such as Telnet, and maybe FTP.[1] For the Internet, they were Ethernet, IP, TCP, Telnet or HTTP, etc. as application. It is important to remember that the ARPANET was built to be a production network to lower the cost of doing research on a variety of scientific and engineering problems.

The CYCLADES group, on the other hand, was building a network to do research on the nature of networks. They were looking at the whole system to understand how it was supposed to work. They saw that layers were more than just local modularity but a set of cooperating processes in different systems, and most importantly different layers had different scope, i.e. number of elements in them. This concept of the scope of a layer is the most important property of layers. The Internet never understood its importance.

The layers that the CYCLADES group came up with in 1972 were the following: 1) the Physical Layer – the wires that go between boxes. 2) The Data Link Layer – that operates over one physical media and detects errors on the wire and in some cases keeps the sender from overrunning the receiver. But most physical media have limitations on how far they can be used. The further data is transmitted on them the more likely there are errors. So these may be short. To go longer distances, a higher layer with greater scope exists over the Data Link Layer to relay the data. This is traditionally called the 3) Network Layer.

But of course, the transmission of data is not just done in straight lines, but as a network so that there are alternate paths. We can show from queuing theory that regardless of how lightly loaded a network is it can have congestion, where there are too many packets trying to get through the same router at the same time. If the congestion lasts too long, it will get worse and worse and eventually the network will collapse. It can be shown that no amount of memory in the router is enough, so when congestion happens packets must be discarded. To recover from this, we need a 4) Transport Layer protocol, mostly to recover lost packets due to congestion. The CYCLADES group realized this which is why there is a Transport Layer in their model. They started doing research on congestion around 1972. By 1979, there had been enough research that a conference was held near Paris. DEC and others in the US were doing research on it too. Those working on the Internet didn’t understand that such a collapse from congest could happen until 1986 when it happened to the Internet. So much for seeing problems before they occur.

Emerson: Before we go on, can you expand more on how and why the Internet collapsed in 1986?

Day: There are situations where too many packets arrive at a router and a queue forms, like everyone showing up at the cash register at the same time, even though the store isn’t crowded. The network (or store) isn’t really overloaded but it is experiencing congestion. However in the Transport Layer of the network, the TCP sender is waiting to get an acknowledgement (known as an “ack”) from the destination that indicates the destination got the packet(s) it sent.  If the sender does not get an ack in a certain amount of time, the sender assumes that packet and possibly others were lost or damaged re-transmits everything it has sent since it sent the packet that timed out.  If the reason the ack didn’t arrive is that it was delayed too long at an intervening router and the router has not been able to clear its queue of packets to forward before this happens, the retransmissions will just make the queue at that router even longer.  Now remember, this isn’t the only TCP connection whose packets are going through this router.  Many others are too. And as the day progresses, there is more and more load on the network with more connections doing the same thing.  They are all seeing the same thing contributing to the length of the queue.  So while the router is sending packets as fast as it can, its queue is getting longer and longer.  In fact, it can get so long and delay packets so much, that the TCP sender’s timers will expire again and it will re-transmit again, making the problem even worse. Eventually, the throughput drops to a trickle.

As you can see, this is not a problem of not enough memory in the router; it is a problem of not being able to get through the queue. (Once there are more packets in the queue than the router can send before retransmissions are triggered, collapse is assured.)  Of course delays like that at one router will cause similar delays at other routers.  The only thing to do is discard packets.

What you see in terms of the throughput of the network vs load is that throughput will climb very nicely, increasing, then it begins to flatten out as the capacity of the network is reached, then as congestion takes hold and the queues get longer, throughput starts to go down until it is just a trickle.  The network has collapsed.  The Internet did not see this coming. Nagel warned them in 1984 but they ignored it.  They were the Internet – what did someone from Ford Motor Company know?  It was a bit like the Frank Zappa song, “It can’t happen here.”  They will say (and have said) that because the ARPANET handled congestion control, they never noticed it could be a problem.  As more and more IP routers were added to the Internet, the ARPANET became a smaller and smaller part of the Internet as a whole and it no longer had sufficient influence to hold the congestion problem at bay.

This is an amazing admission. They shouldn’t have needed to see it happen to know that it could. Everyone else knew about it and had for well over a decade. CYCLADES had been doing research on the problem since the early 1970s.  The Internet’s inability to see problems before they occur is not unusual.  So far we have been lucky and Moore’s Law has bailed us out each time.

Emerson: Thank you – please, continue on about what Cyclades did that TCP should have done.

Day: The other thing that CYCLADES noticed about layers in networks was that they weren’t just modules and they realized this because they were looking at the whole network. They realized that layers in networks were more general because they used protocols to coordinate their actions in different computers. Layers were distributed share states with different scopes. Scope? Think of it as building with bricks. At the bottom, we use short bricks to set a foundation, protocols that go a short distance. On top of that are longer bricks, and on top of that longer yet. So what we have is the Physical and Data Link Layer have one scope; the Network and Transport Layers have a larger scope over multiple Data Link Layers. Quite soon, circa 1972, researchers started to think about networks of networks. The CYCLADES group realized that the Internet Transport Layer was a layer of greater scope yet it also operated over multiple networks. So by the mid-1970s, they were looking at a model that consisted of Physical and Data Link Layers of one small scope that is used to create networks with a Network Layer of greater scope, and an Internet Layer over multiple networks of greater scope yet. The Internet today has the model I described above for a network architecture of two scopes, not an internet of 3 scopes.

Why is this a problem? Because congestion control goes in that middle scope. Without that scope, the Internet group put congestion control in TCP, which is about the worse place to put it and thwarts any attempt to provide Quality of Service for voice and video, which must be done in the Network Layer and ultimately precipitated a completely unnecessary debate over net neutrality.

Emerson: Do you mean that a more sensible structure to handle network congestion would have made the issue of net neutrality beside the point? Can you say anything more about this? I’m assuming others besides you have pointed this out before?

Day: Yes, this is my point and I am not sure that anyone else has pointed it out, at least not clearly.  It is a little hard to see clearly when you’re “inside the Internet.”  There are several points of confusion in the net neutrality issue. One is that most non-technical people think that bandwidth is a measure of speed when it is more a measure of capacity.  Bits move at the speed of light (or close to it) and they don’t go any faster or slower. So bandwidth really isn’t a measure of speed. The only aspect of speed in bandwidth is how long it takes to move a fixed number of bits and whatever that is consumes capacity of a link. If a link has a capacity of 100Mb/sec and I send a movie at 50Mb/sec, I only have another 50Mb/sec I can use for other traffic. So to some extent, talk of a “fast lane” doesn’t make any sense. Again, bandwidth is a matter of capacity.

For example, you have probably heard the argument that Internet providers like Comcast and Verizon want “poor little” Netflix to pay for a higher speed, to pay for a faster lane. In fact, Comcast and Verizon are asking Netflix to pay for more capacity! Netflix uses the rhetoric of speed to wrap themselves in the flag of net neutrality for their own profit and to bank on the fact that most people don’t understand that bandwidth is capacity. Netflix is playing on people’s ignorance.

From the earliest days of the Net, providers have had an agreement that as long as the amount of traffic going between them is about the same in both directions they don’t charge each other. In a sense it would “all come out in the wash.” But if the traffic became lop-sided, if one was sending much more traffic into one than the other was sending the other way, then they would charge each other. This is just fair.  Suddenly, because movies consume a lot of capacity, Netflix is generating considerable load that wasn’t there before. This isn’t about blocking a single Verizon customer from getting his movie; this is about the 1000s of Verizon Customers all downloading movies at the same time and all of that capacity is being consumed at a point between Netflix’s network provider and Verizon.  It is even likely they didn’t have lines with that much capacity, so new ones had to be installed.  That is very expensive.  Verizon wants to charge Netflix or Netflix’s provider because the capacity moving from them to Verizon is now lop-sided by a lot.  This request is perfectly reasonable and it has nothing to do with the Internet being neutral. Here’s an analogy: imagine your neighbor suddenly installed an aluminum smelter in his home and was going to use 10,000 times more electricity than he use to.  He then tells the electric company that they have to install much higher capacity power lines to his house and provide all of that electricity and his monthly electric bill should not go up. I doubt the electric company would be convinced.

Net neutrality basically confuses two things: traffic engineering vs discriminating against certain sources of traffic. The confusion is created because of the flaws introduced fairly early and then what that forced the makers of Internet equipment to do to try to work around those flaws.  Internet applications don’t tell the network what kind of service they need from the Net.  So when customers demanded better quality for voice and video traffic, the providers had two basic choices: over provision their networks to run at about 20% efficiency (you can imagine how well that went over) or push the manufacturers of routers to provide better traffic engineering. Because of the problems in the Internet, about the only option open to manufacturers was for them to look deeper into the packet than just making sure they routed the packet to its destination.  However, looking deeper into a packet also means being able to tell who sent it. (If applications start encrypting everything, this will no longer work.)  This of course not only makes it possible to know which traffic needs special handling, but makes it tempting to slow down a competitor’s traffic.  Had the Net been properly structured to begin with (and in ways we knew about at the time), then these two things would be completely distinct: one would have been able to determine what kind of packet was being relayed without also learning who was sending it and net neutrality would only be about discriminating between different sources of data so that traffic engineering would not be part of the problem at all.

Of course, Comcast shouldn’t be allowed to slow down Skype traffic because it is in competition with Comcast’s phone service.  Or Netflix traffic that is in competition with its on-demand video service. But if Skype and Netflix are using more than ordinary amounts of capacity, then of course they should have to pay for it.

Emerson: That takes care of three of the five flaws in TCP. What about the next two?

Day: The next two are somewhat hard to explain to a lay audience but let me try. A Transport Protocol like TCP has two major functions: 1) make sure that all of the messages are received and put in order, and 2) don’t let the sender send so fast that the receiver has no place to put the data. Both of these require the sender and receiver to coordinate their behavior. This is often called feedback, where the receiver is feeding back information to the sender about what it should be doing. We could do this by having the sender send a message and the receiver send back a special message that indicates it was received (the “ack” we mentioned earlier) and to send another. However, this process is not very efficient. Instead, we like to have as many messages as possible ‘in flight’ between them, so they must be loosely synchronized. However, if an ack is lost, then the sender may conclude the messages were lost and re-transmit data unnecessarily. Or worse, the message telling the sender how much it can send might get lost. The sender is waiting to be told it can send more, while the receiver thinks it told the sender it could send more. This is called deadlock. In the early days of protocol development a lot of work was done to figure out what sequence of messages was necessary to achieve synchronization. Engineers working on TCP decided that a 3-way exchange of messages (3-way handshake) could be used at the beginning of a connection. This is what is currently taught in all of the textbooks. However, in 1978 Richard Watson made a startling discovery: the message exchange was not what achieved the synchronization. It was explicitly bounding three timers. The messages are basically irrelevant to the problem. I can’t tell you what an astounding result this is. It is an amazingly deep, fundamental result – Nobel Prize level! It not only yields a simpler protocol, but one that is more robust and more secure than TCP. Other protocols, notably the OSI Transport Protocol, incorporate Watson’s result but TCP only partially does and not the parts that improves security. We have also found this implies the bounds of what is networking. If an exchange of messages requires the bounding of these timers to work correctly, it is networking or interprocess communication. If they aren’t bounded, then it is merely a remote file transfer. Needless to say, simplicity, working well under harsh conditions (or robustness), and security are all hard to get too much of.

Addressing is even more subtle and its ramifications even greater. The simple view is that if we are to deliver a message in a network, we need to say where the message is going. It needs an address, just like when you mail a letter. While that is the basic problem to be solved, it gets a bit more complicated with computers. In the early days of telephones and even data communications, addressing was not a big deal. The telephones or terminals were merely assigned the names of the wire that connected them to the network. (This is sometimes referred to as “naming the interface.”) Until fairly recently, the last 4 digits of your phone number were the name of the wire between your phone and the telephone office (or exchange) where the wire came from. In data networks, this often was simply assigning numbers in the order the terminals were installed.

But addressing for a computer network is more like the problem in a computer operating system than in a telephone network. We first saw this difference in 1972. The ARPANET did addressing just like other early networks. IMP addresses were simply numbered in the order they were installed. A host address was an IMP port number, or the wire from the IMP to the host. (Had BBN give a lot of thought to addressing? Not really. After all this was an experimental network. The big question was, would it work at all!!?? Let alone could it do fancy things! Believe me, just getting a computer that had never been intended to talk to another computer to do that was a big job. Everyone knew that addressing issues were important, difficult to get right, so a little experience first would be good before we tackled them.) Heck, the maximum number of hosts was only 64 in those days.)

In 1972, Tinker AFB joined the ‘Net and wanted two connections to the ARPANET for redundancy! My boss told me this one morning, and I first said, ‘Great! Good ide . . . ‘ I didn’t finish it and instead, I said, O, cr*p! That won’t work! (It was a head slap moment!) 😉 And a half second after that said, ‘O, not a big deal, we are operating system guys, we have seen this before. We need to name the node.’

Why wouldn’t it work? If Tinker had two connections to the network, each one would have a different address because they connected to different IMPs. The host knows it can send on either interface, but the network doesn’t know it can deliver on either one. To the network, it looks like two different hosts. The network couldn’t know those two interfaces went to the same place. But as I said, the solution is simple: the address should name the node, not the interface.[2]

Just getting to the node is not enough. We need to get to an application on the node. So we need to name the applications we want to talk to as well. Moreover, we don’t want the name of the application to be tied to the computer it is on. We want to be able to move the application and still use the same name. In 1976, John Shoch put this into words as: application names indicate what you want to talk to; network addresses indicate where it is; and routes tell you how to get there.

The Internet still only has interface addresses. They have tried various work-arounds to solve not having two-thirds of what is necessary. But like many kludges, they only kind of work, as long as there aren’t too many hosts that need it. They don’t really scale. But worse, none of them achieve the huge simplification that naming the node does. These problems are as big a threat to the future of the Internet as the congestion control and security problems. And before you ask, no, IPv6 that you have heard so much about does nothing to solve them. Actually from our work, the problem IPv6 solves is a non-problem, if you have a well-formed architecture to begin with.

The biggest problem is router table size. Each router has to know where next to send a packet. For that it uses the address. However for years, the Internet continued to assign addresses in order. So unlike a letter where your local post office can look at the State or Country and know which direction to send it, the Internet addresses didn’t have that property. Hence, routers in the core of the ‘Net needed to know where every address went. As the Internet boom took off that table was growing exponentially and was exceeding 100K routes. (This table has to be searched on every packet.) Finally in the early 90s, they took steps to make IP addresses more like postal addresses. However, since they were interface addresses, they were structured to reflect what provider’s network they were associated with, i.e. the ISP becomes the State part of the address. If one has two interfaces on different providers, the problem above is not fixed. Actually, it needs a provider-independent address, which also has to be in the router table. Since even modest sized businesses want multiple connections to the ‘Net, there are a lot of places with this problem and router table size keeps getting bigger and bigger, now around 500K and 512K is an upper bound that we can go beyond, but it impairs adoption of IPv6 to do so. In the early 90s, there was a proposal[3] to name the node rather than the interface. But the IETF threw a temper tantrum refused to consider breaking with tradition. Had they done that it would have reduced router table size by a factor of between 3 and 4, so router table size would be closer to 150K. In addition, naming the interface only makes doing mobility a complex mess.

Emerson: I see – so, every new “fix” to make the Internet work more quickly and efficiently is only masking the fundamental underlying problems with the architecture itself. What is the last flaw in TCP you’d like to touch on before we wrap up?

Day: Well, I wouldn’t say ‘more quickly and efficiently.’ We have been throwing Moore’s Law at these problems: processors and memories have been getting faster and cheaper faster than the Internet problems have been growing, but that solution is becoming less effective. Actually, the Internet is becoming more complex and inefficient.

But as to your last question, another flaw with TCP is that it has a single message type rather than separating control and data. This not only leads to a more complex protocol but greater overhead. They will argue that being able to send acknowledgements with the data in return messages saved a lot of bandwidth. And they are right. It save about 35% bandwidth when using the most prevalent machine on the ’Net in the 1970s, but that behavior hasn’t been prevalent for 25 years. Today the savings are miniscule. Splitting IP from TCP required putting packet fragmentation in IP, which doesn’t work. But if they had merely separated control and data it would still work. TCP delivers an undifferentiated stream of bytes which means that applications have to figure out what is meaningful rather than delivering to a destination the same amount the sender asked TCP to send. This turns out to be what most Applications want. Also, TCP sequence numbers (to put the packets in order) are in units of bytes not messages. Not only does this mean they “roll-over” quickly, either putting an upper bound on TCP speed or forcing the use of an extended sequence number option which is more overhead. This also greatly complicates reassembling messages, since there is no requirement to re-transmit lost packets starting with the same sequence number.

Of the 4 protocols we could have chosen in the late 70s, TCP was (and remains) the worse choice, but they were spending many times more money than everyone else combined. As you know, he with the most money to spend wins. And the best part was that it wasn’t even their money.

Emerson: Finally, I wondered if you could briefly talk about RINA and how it could or should fix some of the flaws of TCP you discuss above? Pragmatically speaking, is it fairly unlikely that we’ll adopt RINA, even though it’s a more elegant and more efficient protocol than TCP/IP?

Day: Basically RINA picks up where we left off in the mid-70s and extends what we were seeing then but hadn’t quite recognized. What RINA has found is that all layers of the same functions they just are focused on different ranges of the problem space. So in our model there is one layer that repeats over different scopes. This by itself solves many of the existing problem of the current Internet, including those described here. But in addition, it is more secure as multihoming and mobility falls out for free. It solves the router table problem because the repeating structure allows the architecture to scale, etc.

I wish I had a dollar for every time someone has said (in effect), “gosh, you can’t replace the whole Internet.” There must be something in the water these days. They told us that we would never replace the phone company, but it didn’t stop us and we did.

I was at a high-powered meeting a few weeks ago in London that was concerned about the future direction of architecture. The IETF [Internet Engineering Task Force] representative was not optimistic. He said that within 5-10 years, the number of Internet devices in the London area would exceed the number of devices on the ‘Net today, and they had no idea how to do the routing so the routing tables would converge fast enough.

My message was somewhat more positive. I said, I have good news and bad news. The bad news is: the Internet has been fundamentally flawed from the start. The flaws are deep enough that either they can’t be fixed or the socio-political will is not there to fix them. (They are still convinced that not naming the node when they had the chance was the right decision.) The good news is: we know the answer and how to build it, and these routing problems are easily solved.

[1] An IMP was an ARPANET switch or today router. (It stood for Interface Message Processor, but is one of those acronyms where the definition is more important than what it stood for.) NCP was the Network Control Program, that managed the flows between applications such as Telnet, a terminal device driver protocol; and FTP, a File Transfer Protocol.

[2] It would be tempting to say “host” here rather than “node,” but one might have more than one node on a host. This is especially true today with Virtual Machines so popular, each one is a node. Actually, by the early 80s we had realized that naming the host was irrelevant to the problem.

[3] Actually, it wasn’t a proposal, it was already deployed in the routers and being widely used.
