Well, I'm developing a java interface between a streaming server and a flash client. I noticed that UDP datagrams can reach my interface out of order even if both processes are running locally.

Is that normal? I thought that as no datagram has to go through any router or any network device, then that should not be happening.

Thanks in advance Nelson R. Perez

Suppose that a given TCP fragment is fragmented into two IP datagrams, and that the first datagram arrives to the TCP server, but the second datagram never arrives. After a certain amount of time the TCP server sends a keepalive, and determines that the client is alive. What does the TCP server then… >>> More
