To get something reliable over UDP, you're going to need to acknowledge everything you're sent, and if you don't hear back an acknowledgement, re-send. Basically reimplement TCP, or parts of it. Why do you need to use UDP? I've used UDP for a number of purposes, but usually in a "fire and forget" system. For instance, my latest use of it was a peer-to-peer self-healing network; each node would broadcast a periodic UDP packet saying "Hi, I'm here, and here's my current status", and each node would keep track of the timestamp when it last received such a packet from each known IP address. If the time-since-last-received exceeds three broadcast intervals, the node is considered to be dead. But for this to work, I have to not care about individual packet loss; there is no data in the packet that won't be repeated in the next one. This is a reliable *system* built on UDP. Can you explain your goals and restrictions? Might help us figure out how to advise. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
