[Twisted-Python] Unreliable UDP
Does Twisted provide any support for reliable UDP? I'm looking for a nice networking library for and real-time (i.e. non-TCP) game development.

First, just use TCP, unless you have already implemented the game using TCP, done performance testing and discovered problems tied to TCP which are resolved by UDP. Assuming you have done that, come up with a list of the kind of traffic your game needs to exchange between hosts. Based on that, you may be able to narrow your search (there are lots of kinds of "reliable" UDP) or you may find that existing solutions aren't suitable. Twisted itself doesn't offer any kind of reliability layering on top of UDP, but there are various Twisted-based projects which use UDP for semi-reliable messaging. Whether any of them might be of use to you depends on how closely your message model matches theirs. Most likely, you'll end up implementing something yourself, assuming you actually need a UDP-based solution at all. Jean-Paul
I think it was Robert Elz who said "Those who do not understand TCP are doomed to repeat it" (in reference to the file sharing protocol FSP). Just use TCP if you need reliable communication.
