[ns] Enque function in dsredq.cc

[Ashraf Matrawy <amatrawy@sce.carleton.ca>]

Hi All,

in dsredq.cc


in redQueue::enque

if the avg queue is greater than the max threshold and ECN is on should
the packet be marked as the code does or should it be dropped

       //now determining whether to drop the packet or not
         u = Random::uniform(0.0, 1.0);

       //drop it
                        if (u <= pa) {
            if (ecn) return PKT_MARKED;
            return PKT_EDROPPED;
         }
      } else { //if avg queue is greater than max. threshold
                        qParam_[prec].edv_.count = 0;
                        if (ecn) return PKT_MARKED;
                        return PKT_DROPPED;


thanks for your help
