When a connection have not received packets for a certain period of time (default 2 hours), it should send KEEP-ALIVE packets.
My question is, who will start sending KEEP-Alive packets, the client, server or both?

What kind of server/client are you using? – Can Kavaklıoğlu Dec 23 '11 at 12:19

I would think it would be the side that initiated the connection. – joeqwerty Dec 23 '11 at 15:10

Either side will, assuming:
- the OS is configured to do so (linux, windows)
- the application configured the socket with SO_KEEPALIVE via setsockopt() (linux, windows).
If both sides have identical keepalive settings, then you'll see them both kick off a keepalive at nearly the same time.
