Count packets actively in Ns2

Question

I have to count packets for each incoming flow actively in RED Queue in Ns2. I have to integrate it in the queue algorithm itself so that changes (in variables of active queues) occur when the packet in queued. For simple codes it's like:

 for each incoming packet
     count[i]=count[i]+packet[i]

How do I say “for each incoming packet” in NS2, and how do I define [i] such that [i] is the IP Address representing different individual flow?

I guess you should look for a callback to let you respond to an incoming/received packet. — Donal Fellows, Jan 22 '17 at 18:31

You can do it by modifying the .cc and .h files of the queue implementation which can be found at

ns-allinone-x.xx\ns-x.xx\queue.
