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 retra=
nsmiitted packet has duplicate sequence numbers in the capture file.  The r=
esults have been OK, but with acuracy that is not good enough.  Under certa=
in conditions (i.e. when entire windows are not retransmitted), it works we=
ll.

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

Thanks,
Barry
