Your question is more suitable for ns-users@isi.edu, so please post follow-ups there. There is not a straightforward answer to your question, since I don't know what script you are looking at, and since the TCP code has lots of options. But you can take a look at the code yourself in tcp/tcp-newreno.cc (and also tcp.cc's function TcpAgent::slowdown()) to see what may be happening. Tom
