How successful is uTP in eliminating congestion is still a matter of discussion. According to some owners of private BitTorrent trackers, uTorrent is no longer playing fair. Since uTorrent users are the only ones using the new protocol, uTorrent favors its own kind over other clients. What this means is that that when connecting to other clients, uTorrent users will give preference to other uTorrent users, behavior that some have declared as ‘unfair’.
Simon Morris, BitTorrent’s VP of Product Management admits that the tracker owners have a point, but says that it is very hard to innovate without having to face such technical downsides.
BitTorrent Inc. has opened up the specifications of the uTP protocol and hosted a conference in their San Fransisco offices a few weeks ago to discuss uTP in detail with developers of some of the most popular Bittorrent clients. According to Morris, other popular client developers have shown interest in implementing uTP into their own applications.
Widespread support for the new protocol would of course be the easiest way to get rid of the unfairness allegations, but uTorrent’s major competitor Vuze has no plans to support uTP in the short term.
So far, only a few private trackers have decided to ban uTorrent and there is no word on how long it would continue. So for the meantime moving to other clients like Vuze makes alot more sense till the issue is resolved.
