[ns] Simulation of i.i.d Bernoulli arrivals

Hi list, I need to simulate traffic which resembles iid Bernoulli arrivals with a given rate and fixed frame size. I tried a Poisson traffic model, but my results did not completely match the ones I wanted to reproduce, though the overall behavior was similar. I am suspecting a traffic issue, a

[ns] Virtual Output Queuing simulation on ns-2

Hi Everyone, I need to simulate a switch that does Virtual Output Queuing, and I have been searching the net for this. So far, I have not been able to find anything related in either the ns-2 sites, or through a cursory look at the code. In the worst case, I guess I would have to make do with n

[ns] Droptail queue per-flow rate limiting using TokenBucket (or other mechanism?)

Hi list, I am currently doing some ethernet level rate limiting simulations using ns-2. I had been doing my simulations with a simple DropTail queue (by physically changing the link rate), but now, I am trying to see if I can apply a Token Bucket implementation to support multiple flows in a sim

[ns] Generating packets on queue events

Hi everyone, I am thinking of generating packets on certain queue events. The packets would be: 1. generated by the link layer (in real life, but not necessarily in ns-2, an approximation would do) 2. processed by the link layer on the receiving end, and acted upon I am thinking of th

[ns] Changing the bandwidth at link level during runtime in ns-2

Hi Everyone, I am trying to change the bandwidth between two links at run-time using ns-2, at the link layer. For example, if the previous bandwidth between nodes n1 and n2 was 2Mbps, I would need to change it to 1Mbps at a certain instant. What I have done so far is to try to manually set the
