Hi, I think I solved the problem. Actually it is not a problem.
I think in ns2.28 the paramater "Queue/RED set queue-in-bytes_ true" is set to true by default. In ns2.27, the parameter is set to false by default. I want the queue size in term of packets. To over ride this just add the following parameter in red.tcl script when using ns228. "Queue/RED set queue-in-bytes_ false" I think this is also apply for ns229. Any reason why we want to monitor the queue in bytes rather than in packest? Cheers, Ben. --- ben <[EMAIL PROTECTED]> wrote: > Hi there, > > My apologies.
