Hello,
there are several possibilities. First you can analyse the trace files
by filtering the interesting event. An example for awk you can find in
the attachment.
Second you my use an statistic toolset like ns2measure. (see google)
Best regards,
Volker

Hi all,
Can i please know how to find throughput if i am sending udp
packets from one node to another.
Thanks..
