There's some standardization work being done in the IETF ALTO working group. They're looking at ways ISPs can inform P2P clints about which peers are "better", I.e., topologically nearby. http://tools.ietf.org/wg/alto/ I'm less familiar with DECADE, but I believe they're working on more directly cache-related stuff. http://tools.ietf.org/wg/decade/ On Sep 25, 2010 4:44 PM, "Matthew Walster" <matthew@walster.org> wrote: On 25 September 2010 21:16, Rodrick Brown <rodrick.brown@gmail.com> wrote:

I once read an article talking about making BitTorrent scalable by using anycasted caching services at the ISP's closest POP to the end user. Given sufficient traffic on a specified torrent, the caching device would build up the file, then distribute that direct to the subscriber in the form of an additional (preferred) peer. Similar to a CDN or Usenet, but where it was cached rather than deliberately pushed out from a locus. Was anything ever standardised in that field? I imagine with much of P2P traffic being (how shall I put this...) less than legal, it's of questionable legality and the ISPs would not want to be held liable for the content cached there? M
