Hi all,
I would appreciate it if you could help me. I am having the same problem, which is importing traced traffic (file) into ns2.31.
what do I need to make it work Network/File?
which ns version do i need to use?
Any solution, link, script or code will be helpful.
Cheers,
moses

I am needing to run a simulation in NS2 that uses
pcap or tcpdump trace files as the traffic in the test.
I don't get any errors with this but I also don't get any traffic.
Do I need to explicitly set routing or is there something else I am missing?
My no-error-non-working example
#Create a simulator object
set ns [new Simulator]
$ns use-scheduler Heap
#Open the NAM trace file
set nf [open pcap_ex.nam w]
$ns namtrace-all $nf
$ns color 400 Green
$ns color 500 Yellow
$ns color 900 Red
#Define a 'finish' procedure
proc finish {} {
global ns nf
$ns flush-trace
#Close the NAM trace file
close $nf
exit 0
}
