[ns] plot of link throughput

[Ishan Mandrekar <ishan@io.ece.drexel.edu>]

Hi all,

I have a simple topology consisting of 2 nodes connected by a duplex link.
The source is a CBR on UDP. I would like to generate a Xgraph plot of the
link throughput. Is there a variable provided by class link which gives a 
measure of the instantaneous traffic.

Thanks,
Ishan.
