Dear ns-users
you need to replace the Queue/DropTail/PriQueue with Queue/CMUPriQueue.
set val(ifq) CMUPriQueue
with the CMUPriQueue the packets will be classified into four queues according
to their type (packet of control first, the packet vedio second, audio packets
third and the rest of
dear ns-users
For get the performance of your protocol, I advice you to disable the ARP module
to do this you djust need to add three instructions at the top of the
ARPTable::arpresolve function in arp.cc file like this
hdr_cmn *ch = HDR_CMN(p);
mac_->hdr_dst((char*) HDR_MAC(p), ch->next_hop
to get the packet enqueue and dequeue time; you shoold work with the trace file
of ns
in the tcl script, you shoold add an instruction to construct a trace file,
you parse this file for calculate the time between r + for (packet enqueue
) and r - for (packet dequeue ).
to parse this file, you

iph->prio_ = codePt; // codePt: the code of priority
hope that answer for your question
