It is all very interesting. Why we did not have such research reported on last NANOG meeting?
also our grad student thomas studying p2p traffic tells me that there is no sense of localization in most (if not all) p2p networks; so i am more likely to download a movie from an
Interesting. Are there any p2P systems which optimize traffic by localizyng it, when possible?
(advertised as) ethernet user in Asia than from downloading from an (advertised as) DSL user next door. and my understanding it that's all based on how the user configures their p2p servent, it's not like the network figures out the available bandwidth to potential remote clients. that's a pretty loose definition of intelligence, believing everything you hear from an end host :)
per seandonelan's reference, yes caida will have 2 papers on p2p traffic analysis by the end of the year, titles 'is p2p traffic dying or just hiding?' [take a guess] and 'transport layer identification of p2p traffic'. check caida web site in october.
but neither study touches on the regional differences, i suspect it's a function of the relative popularity, ease-of-use, and type-of-content-served of certain applications in each place. i lend less weight to the differences than the similarities. killer app, indeed.
