Hi Radhika, Thanks for your answer.
My system consists of Traffic generator replaying some recorded traces. I would like to measure the latency & bandwidth of my system attached with traffic generator. Just a side question - After running the trace I see that there is stat called 'numRetries' and 'retryTicks' , which are the ticks wasted during back pressure. So my question is, does CommMonitor has the ability to count latency of packet if the packet experiences a back-pressure and retry is being done from traffic generator.
