Sectionalizing Network Loss with TCP

[Barry Constantine <Barry.Constantine () jdsu com>]

Hello,

I am trying to develop a technique to isolate packet loss between networks (i.e. Network A versus Network B loss 
diagnosis).

I've experimented with the common technique that identifies whether a retransmiitted packet has duplicate sequence 
numbers in the capture file.  The results have been OK, but with acuracy that is not good enough.  Under certain 
conditions (i.e. when entire windows are not retransmitted), it works well.

Has anyone on this list developed a technique using tshark + scripting?

Thanks,
Barry
