[ns] tracing a flow

[bsikdar@networks.ecse.rpi.edu]

hi everyone,
	i have a simulation scenario with multiple flows going
through a bottleneck link and I am interested in the dynamics
of one particular flow. Instead of doing a "namtrace-all" which
results in a large file and traces all flows, is there a way i
can just trace a single flow?

	also, is there any way to monitor the window size (cwnd)
of a TCP flow? Thanks,
