[p2p-hackers] Using UDT for swarming

[Matthew Kaufman]

This protocol is clearly designed to operate in something other than today's
consumer Internet. It was designed to outperform traditional TCP over large
delay*bandwidth networks, but actually gives TCP the edge in more typical
network settings. For file transfers over actual connections you're likely
to see (unless you have a GigE plugged right into Internet2 on your desk),
TCP is a better choice, and if you need UDP for NAT traversal or other
reasons, there are better performing (and simpler to implement, as this
requires things like fine-grained clocks) choices. And if your design
parameter is large numbers of streams with vastly different RTTs and you
wanted to improve over TCP's handling of this, you'd make different choices
than were made for UDT.
