Hi Thomas,

Good to "see" you again   ;-)

I did come up with this question before. I think the problem is that TCP
buffers the application data, and adapt to a link congestion, so even if
you stop the application traffic, TCP agent still have some data in the
buffer to send.

If you run your simmulation in a too short time, you can not see the TCP
traffic stopping. Try running your simmulation longer, and remember to
stop your TCP traffic early enough, let say 5 second before you stop
your simulation.
