In line with the summary functionality that I described earlier, is there
any way to have a variable be in the global for a conversation? As an
example, the latency of an RTP packet depends on the latency of the
previous packet. Is there a way for me to save a variable in the
conversation space (i.e. a conversation between machines a and b on ports
2000 and 1000 has one latency, while a conversation between machines a and
b on ports 2002 and 1002 has another latency)?
The next question is what is the best way to check to see if the packet
that is currently being run through the dissector has already run before?
Like in the above situation, I want to calculate the latency of the current
packet. When ethereal dissects all of the packets to begin with, the
latency is correct. Once the packet is clicked on 10 times in the GTK
window, the latency is no longer correct because every click causes
ethereal to dissect the packet over again. This is also critical to some
variable that accumulates across all packets in a conversation. An example
of this is calculating jitter for RTP packets. It's the sum of all of the
packet specific jitters.
Thanks!

Be nice or I'll replace you with a very
small shell script.
