[ns] enque and deque the queue of a node in trace file

[linda rep]

than kyou Daniel for your help,

I an not interesting to the queue of the link but i am interesting by the
queue of the node which is between the LL layer et the MAC layer, I want to
saturate the network and i want to know how many packets is there in the
queue.

in my trace file i have not the + corresponding to the enque of the packet
and the - corresponding to the dequeue of the packet from the queue.

Thank you in advance,
Regards,

Lynda,
