Jon Crowcroft's interview is quite interesting in that he claims that heat loading at data centers will make distribution of video through traditional client server models impossible, and that peer to peer (P2P) will be the only practical way of distributing such content. In testament to that fact there is an explosion of new companies gearing up to deliver video and other content via P2P including Joost, Vudu, etc. This is why many argue that the traditional telco NGN architecture with IPTV is doomed to failure. But P2P imposes its own sort of problems on today's Internet architectures as witnessed by the attempts of many service providers to limit P2P traffic or ban it outright.
If P2P is indeed going to be the major mode of delivery of data, especially for video then we need to explore new Internet architectures. As Van Jacobson has pointed out - too much network research is focused on the Internet as a traditional telecommunications medium of "channels" from A to B. As a result Internet research, especially in the optical and network world is largely about topology optimization, network layers, reliability, redundancy, etc
Universities to my mind should be at the forefront of exploring ways to build and deploy a new Internet - not only for the research community, but for the global community as well. But sadly many universities are also trying to restrict P2P traffic, and in some cases act as the snarling guard dog for the RIAA and MPAA. Students at universities are the early adopters of new technology (much more so than their ageing professors)- rather than discouraging their behaviour -we should see them as an opportunity to test and validate new Internet architectures and services. See my presentation at Net@Edu on some thoughts on this topic
P2P may fundamentally reshape our thinking of network architectures such as enabling the end user to do their own traffic engineering and network optimization to reach the closest P2P node or transit exchange point.
