I think even I am getting confused. I have a group of processes on a box that will always be on the same box, so I was looking for a fast way for them to communicate. My options are:
TCP over loopback Unix Domain Sockets Pipes Pipes will not fulfill my needs, so I was looking into Unix Domain Sockets(UDS). Since there are no NIO providers for UDS, I was interested in writing my own and that is when I posed the question to the list. But if TCP over loopback is not going to be any faster than UDS, then I will stick with TCP over loopback. UDP is not an option because I cannot drop packets. Sorry for the confusion. I hope this clears things up.
