If squid could provide a traffic localising solution which is just another traffic sink or source (e.g. a server) to an ISP, rather than something that requires enabling knobs on the network infrastructure for special handling or requires special traffic engineering for it to work, I'd think you'd get quite a bit of interest.I think there's interest from the consumer level, already: http://torrentfreak.com/review-the-wireless-BitTorrent-router/ It's early days, but if this becomes the norm, then the end-users themselves will end up doing the caching.
Maybe I haven't understood what that exactly does, however it seems to me that's really just a bit-torrent client/server in the ADSL router. Certainly having a bittorrent server in the ADSL router is unique, but not really what I was getting at. What I'm imagining (and I'm making some assumptions about how bittorrent works) would be bittorrent "super" peer that : * announces itself as a very generous provider of bittorrent fragments. * selects which peers to offer it's generosity to, by measuring it's network proximity of those peers. I think bittorrent uses TCP, and it would seem to me that TCP's own round trip and througput measuring would be a pretty good source to measuring network locality. * This super peer could also have it's generosity announcements restricted to certain IP address ranges etc. Actually, thinking about it a bit more, for this device to work well it would need to somehow be inline with the bit torrent seed URLs, so maybe that wouldn't be feasible to have a server in the ISP's network do it. Still, if BT peer software was modified to take into account the TCP measurements when selecting peers, I think it would probably go a long way towards mitigating some of the traffic problems that P2P seems to be causing.
