Delay Tolerant Networking -- where we are and where we are going

Over the last few years, Delay Tolerant Networking (DTN) has been exploring
the problems associated with communications in difficult environments that
may be subject to disruption and disconnection. Researchers in the area of
wireless networks have begun to take note that attempting to utilize the
Internet's TCP/IP protocols directly over wireless networks do not handle
disruptions well, and that other techniques involving store and forward
message delivery, such as DTN, may be appropriate. In this talk I will
briefly review DTN technology, and then move on to ongoing technical
developments and a discussion of several DTN deployments planned in the near

Invited Speaker: Jon Crowcroft - Cambridge University
Network Architecture Research Considerations Or The Internet Conspiracy

Very few people can really do architecture research. Indeed, it isn't
obvious to me that anyone ever really does architecture research
(apart from le Courbusier and folks like him). Architecture emerges
from a collection of ideas.

The Internet emerged from a set of disjoint ideas such as
packet switching, decentralised routing, datagram switching,
statistical multiplexing, and so forth. The original
protocols in the ARPANET (NCP) and the Public Data Nets (x.25) were
not actualyl very different. The seperation of NCP into IP and TCP,
with the emergent property of the end-to-end nature of TCP, and the
fate-sharing property of stateless IP were not by careful design - few
of the documents at the time report on this. THe debate on
connectionless versus connection oriented was a post-hoc one, and
indeed there were many sucesful networks of both types (XNS, DECNET
and IP being the former, X.25, SNA and ATM being the latter); Not
forgetting the digital telephone, and cellular networks, which haev
grown by more than 500M nodes in the last 12 months alone.

Many of the architectural choices for a successor to the Internet (or
the wireless and sensor networks of the future) lie in a mixture of
the components of the past, perhaps with some new twist, as yet
impossible to predict.

On the other hand, there is a large body of incremental research that
we can do to explore the design space, which really should, today, be
carried out in a way that will let one evaluate future Grand Designs
effectively. Much of this work should be oriented around instrumented
testbeds and verifiable measurement, since this gives creedance to the
outputs from the research.

In this talk, I'll outline how Haggle is an example of this type of
research, and how innovatie software platforms can be built and shared
to enable others to extend the leverage possible from a limited
research effort.

I will also make some remarks about the FIND and GENI efforts in the
US, along the lines that they really mainly exist to fill a funding
gap in normal networking research that was left when DARPA stopped
funding open research (and went headlong into the poorly justified,
ill thought out, and badly managed waste of money that is Homeland
Defense) and the NSF failed to get the money taken from DARPA:)

We have neither of these problems in Europe but we have a larger
succesful example of networking research (cellular) that is an
artfeact of our community than the US has (the Internet), and so we
have nothing to learn especially from them)

Who will win the content battle?

In every non-vertically integrated industry producers and distribution
channels engage in an ongoing battle to gain a larger share of the
consumers' spending. This battle is characterized by a series of
short-term equilibria: a change in technology or market structure
usually allows one or the other player to gain more of the value chain,
disturbing the current structure, and leading to a new equilibrium. In
the context of the digital content industry, which includes book and
film publishing, newspapers and magazines, and TV and cable channels,
several revolutionary changes have disturbed the previous equilibrium:

a. The Internet as a distribution medium has disintermediated
traditional channels such as book publishers (wikipedia vs.
Britannica), music houses (RIAA vs. Napster), and TV (CBS vs. YouTube).
b. Content production itself has become highly decentralized, with
large volumes of content being produced by the public, rather than
highly-paid 'talent', as evidenced by the success of YouTube and
wikipedia, and enabled by the search engines.
c. On the other hand, owners of coveted distribution channels, such
as cellular spectrum, are still able to charge heavy tolls on content.
Consolidation in the ISP space has emboldened former pure- play
carriers, such as SBC, to similarly extract additional distribution
fees, raising a furore on 'net neutrality'.
d. Finally, entities such as Amazon, Microsoft and Google, who have
traditionally never been either content producers or distribution
channels, seem to want to be both.

In the face of these changes, how will the digital content ecosystem of
the future look like, and what will be the dominant trends in its
evolution? In other words, who will win the content war? The panelists
in this session will offer their prognostications, and, with the
participation of the audience, we will perhaps reach some high-level
