The RTT and TSG are both, if I remember correctly, implementations of TCPtrace and so the pages at www.tcptrace.org will probably explain a lot. The TSG is probably one of the more useful graphs around for diagnosing various throughput problems over E2E connections. http://www.tcptrace.org/manual/time-seq.html We use TSGs quite a lot here at PSC and Matt Mathis has often used them as the preliminary investigative tool in our work on high performance network diagnostics.

Hello,

I have some problems to understand traces of TCP stream analysis (v 0.9.6)
particularly with :
      +Time/Sequence graph
               - why are there two curves on the graph ?
               - what do these curves mean ?
      + RTT graph
               - what do segments represent ?

I hope that you will explain me  that clearly. ( I'm a new user of ethereal )

In wait for a response

Thanks
