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
