Hi,
Based on what I read in NS manual, FullTcp agent supports TCP
three way handshaking but I don't know if it is possible to
monitor this process or not.
And also, I've got a problem with this agent.Could you take
a look at the following script and tell me why it gives an
error on "new Agent/TCP/FUllTcp" ? I am using ns-2.34 all in
one package.
Thanks,
Mobin
