Re: [ns] How to monitor TCP througput?
Agent/LossMonitor cannot be used with TCP flows: it does not provide the
necessary functionnalities for handshaking and stuff.
TCP troughput could be observed from trace files postprocessing thought. There
are a few examples in tcl/ex and tcl/test. grep for awk.
