Hi,

In what sense are TCP sockets full duplex? Sure, data can flow in each
direction independent of the other direction, but it wont work if this
happens at the same time.

THat is, if a client and server process simultaneously send (thats
full-duplex) one window's worth of data on their connection, theyll
deadlock, each waiting for the other to acknowledge receipt, which is not
going to happen.

So the programming has to be symmetric right? One sends, other receives -
that makes it half duplex. Could anyone shed some light on this?

Thanks
Akshay
