Hi All, I'm pretty new to ns-2. So, how could I realize some kind of TCP-Forwarder? The Forwarder is a simple TCP receiver storing packets in a buffer. The sending part of the Forwarder (regular TCP sender) will forward the buffered packets asap. +---------------+ Tcp -------> | TcpSink / Tcp | ------> TcpSink +---------------+ What's the easiest way to realize it? Cheers, Markus
