Hi everyone, I have extend ns2 to study congestion as part of my internship project. What I need is to implement a mechanism by which if a link is over loaded (queue almost full) then it should signal the upstream neighbor and ask to slow down. That will cause the queue at that link to increase. That will cause the congestion to propagate and ultimately reach the source. I want to study the system behavior in such scenario. Any ideas about how this can be done? Thank you.
