UDP Heartbeat

[DaBoonDockSaint]

I been experimenting a lot lately with RS232 and UDP packets and I just recently read an article about UDP Heartbeat packets, I was wondering if any experienced programmers have ever worked with a UDP heartbeat and how you could gather that information?

UDP is a network protocol, like TCP, .Net has UdpClient for this as it has a TcpClient that both use a Socket.

"Heartbeat" means a message based polling system for the different clients to actively see that other clients are still alive, in the most basic form for example a "hello" message that may or may not require a "hello" reply, in more advanced cases the message can contain up to date information about various things that matter. If you include as timestamp in the message the receiver may calculate and monitor transfer time.
