   communication with Socket
  My One computer is broadcasting UDP packets to every computerthrough  LAN on 6112 port. I have a computer which is running 2 process on 6112 port. But both process is not receiving data parallely. My major concern to fetch data either on both process or any one process continuously. Can i set priority of socket ??   
  You cannot set the priority of a socket.UDP receipt when multiple processes are listening on the same port is inherently non-deterministic.If you want to "sniff" traffic, you pretty much need to use a raw socket in "sniffing" mode, using a library such as pcap (on Linux) or WinPcap (on Windows).
