I like the way they are spinning this. The new protocol, over UDP, is more difficult for ISPs to throttle without harming everything else on UDP (VoIP, games, streaming video, etc) that people regularly use (AFAIK.) That being said, they really did create the new protocol to have more elegant throttling. Morris: "It’s not QoS, but rather a congestion management mechanism implemented at the end-user’s layer 7 [Application]. This will stop uTP from eating up traffic bandwidth reserved for latency sensitive apps like VoIP and gaming. What’s more, the congestion management mechanism isn’t something we implemented as an afterthought – it’s the whole point of uTP." from http://torrentfreak.com/utorrent-2-0-to-elimininate-the-need-for-isp-throttling-091031/ http://torrentfreak.com/utorrent-2-0-to-elimininate-the-need... Looking forward to it, even though Comcast doesn't seem throttle my BitTorrent traffic at my location (North Bay area.)

Who's spinning it that way? I didn't see that in the article. Also, DPI or traffic analysis can easily distinguish different UDP-based protocols.

  Is that really feasible for ISPs? I know you can traffic shape anything, but would they bother? I remember there was a pretty big ruckus when this was first announced, since many of the uT guys were talking about how it would be much harder to throttle.

    ISPs can detect BitTorrent traffic today and I don't see why uTP would be any harder to detect than the classic BitTorrent protocol.

    Obviously you don't live in Canada. Over here, all the major ISPs do DPI to throttle torrents and about 6 months back the only way to not be throttled was to go with a smaller DSL ISP that leased lines from Bell. Then, one day, Bell turned around and started doing DPI on wholesale client lines and throttling their torrent traffic too. Some people raised a stink about it and it got to the CRTC for a decision and, in typical CRTC fashion, they issued a non-decision that essentially said DPI should only be used when necessary. Nothing changed. It's now impossible* to get an internet line that doesn't throttle torrents in most of Canada. * Not impossible to run torrents without being throttled though, you just have to set Azureus to its "RC5 encryption" settings and Bell won't be able to analyze your packets though this will break any private trackers that don't use https (most do).
