[ns] problems using ns

[Arijit Ganguly <arijitg@tct.hut.fi>]

hello ns users
while tracing the enque and deque operations on a queue, using the
trace-queue utility, i observed the following

In a number of cases the time for Enque and Deque operations was the
same for a packet.
for example
+ 0.014 ******
- 0.014 ******

This means the ns doesn't model the queueing delay. I tried to increase
the precision, but still the times were the same.

I want to get the current queue size during the enque and deque, as a
funtion of time.
Now problem i am facing is what value do i take for queue size at, say
0.014 sec. (refering to above output).

your replies would be highly appreciated.
thank you
