Is this the same uDP that was in bittorrent mainline blog post recently?

  no, that's μTP. UDP is a 30-year-old protocol: http://tools.ietf.org/html/rfc768 http://tools.ietf.org/html/rfc768 it's substantially faster than TCP because it doesn't provide any guarantees (e.g. error checking); consequently it's more difficult to work with. this protocol builds on top of UDP to provide all of the nice guarantees that TCP does.

    Like most people, you've missed the point of TCP. Error-checking is trivial -- congestion control is HARD
    • m0th87 17y ago
      This is true, but my understanding is TCP's congestion control mechanism is far from ideal and the root cause of its performance problems.

    Ah, yes, μTP is what I meant.
