Re: [ns] Queue Monitor

Hi,
thanks for the quick reply. 
As per the trace file below, how can i obtain the size of the queue at the given instance of time. In the trace file, the queue size I think is in bytes and packets in columns 4 & 5.. but they seem to be negative and keep increasing, when at a particular instant of time, not more than packet ever resides in the queue due to the fact that the link has much larger capacity than the traffic flowing over it.
Please suggest.
Thanks.

if u consider your Q to be a M/D/1 Q, you will see that you may have a non
zero Q size.
