Hi Barry,
You may find the above paper useful for understanding the challenges of TCP packet loss calculation.
cheers,

Subject: [Wireshark-users] Sectionalizing Network Loss with TCP

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
