I think your question is very vague and does not really provide much background info, so you need to do your homework and learn how to ask a question, before posting it here.

I am assuming that you are asking what the main libraries should be / what the main design methodology should be.

Have you considered using libevent (C http://monkey.org/~provos/libevent/) or EventMachine (Ruby - http://rubyeventmachine.com/ )?

Basically, using evented I/O is great if you want to design a scalable server that might possibly have many clients talking over a network... (i.e., many simultaneous connections).

This is as opposed to using select() on sockets that you open up and poll for activity.
