Hi all!
I think there is a bug in the DiffServ module of ns (version 2.32), namely in the implemetation of the RED algorithm. In my opinion the wrong line is in file diffserv/dsredq.cc line number 239 in function redQueue::enque : "return PKT_DROPPED;" This is the case when the RED drops a packet because the average queue is greater than the max. threshold. I think the above line should be "return PKT_EDROPPED;" because PKT_DROPPED should happen only when the link drops a packet. When the RED algorithm drops a packet it should be early drop (PKT_EDROPPED). Please let me know if I am right or not. Regards, Miklos Lengyel
