Hi, TCP windowing is a mechanism to avoid congestion. "A TCP window the amount of outstanding (unacknowledged by the recipient) data a sender can send on a particular connection before it gets an acknowledgment back from the receiver that it has gotten some of it."
In \ns-2.30\tcp\tcp.cc just search for the word window_ , you will notice the bindings with TCl objects. You go through this file for complete understanding of the mechanism. Hope that helps. Sourabh Bora Rochester
