I'm quickly approaching my posting limit for the day (week?) but I can't resist telling you the following story:
I recently found myself somewhere where BitTorrent is severely throttled. Although I can download over HTTP at megabytes per second, BitTorrent downloads wouldn't go faster than 10 kilobytes per second.
Turns out that the newest Azureus (BitTorrent application) supports IPv6. Enabled this and lo and behold: I got about 75 peers, 5 of which were IPv6, the rest IPv4. Of the IPv6 peers, one had a regular IPv6 address, the other four 6to4 addresses. Even though the 70 IPv4 peers could only give me 10 kB/s, the 5 IPv6 peers pushed my download well beyond 100 kB/s.
So under the right circumstances, a little IPv6 can go a long way.
Iljitsch, This matches with the questions i DIDN'T ask Jordi last week: p2p ipv6 traffic? but which applications are generating it? MSN? I was not aware that a "somewhat popular" bittorrent client was doing v6... I remember that some years ago, some people from 6NET and other projects approached the guy which developed the protocol and he sort of refused to cooperate in the effort of making it v6 compatible. Then, afaik some people developed a patch, but of course that didn't reflect into real usage... :-( Cheers, ------------------------------------------------------------------------- Carlos Friac,as See: Wide Area Network Working Group (WAN) www.gigapix.pt FCCN - Fundacao para a Computacao Cientifica Nacional www.ipv6.eu Av. do Brasil, n.101 www.6diss.org 1700-066 Lisboa, Portugal, Europe www.geant2.net Tel: +351 218440100 Fax: +351 218472167 www.fccn.pt ------------------------------------------------------------------------- The end is near........ see http://ipv4.potaroo.net "Internet is just routes (217118/774), naming (billions) and... people!"
