Re: [ns] How to det actual virtual queue size in Nortel's Diffserv?

[Xiang <ns@cdnet.edu.cn>]

Hi,
Thank you for your help. I've done the following things:
1. Add function redQueue::getVirtualLength()  into dsredq.cc:A

    int redQueue::getVirtualLength(int prec) {

       return(qParam_[prec].qlen);
    }

2. Add following line into dsREDQueue::command( ) in dsred.cc:

     if (strcmp(argv[1], "getVirtualLength") ==0) {
                Tcl& tcl = Tcl::instance();
                 tcl.resultf("%f",
redq_[atoi(argv[2])].getVirtualLength(atoi(argv[3])));
                 return(TCL_OK);
        }
I want to use TCL command : "$dsredq getVirtualLenth 0 0" to get queue
length of virtual queue 0 in physical queue 0 in anytime I want. But when I
run TCL script,  I got result 0 all through the simulation time. I don't
know why. Could you help me?
Thank you very much!
