Why is normalized drain rate set to 1 when the drain rate is less than b*(1/nPrior) about ns3-datacenter

In addition, can you please explain why the code have the following operation on the queue output speed: "Deq[dequeueIndex]+=1472;" As

ns3-datacenter/simulator/ns-3.35/src/traffic-control/model/gen-queue-disc.cc

Line 583 in 78fd924

Deq[dequeueIndex]+=1472;

Hi,

Regarding the first question: You are right. This is actually related to round-robin scheduling that we use here. Ideally, we want the 'th' to be within the bounds 1/n and 1.

Regarding the second question: This is to "elastically" reset the dequeue rate of empty queues. The threshold is supposed to capture the "steady state" dequeue rate. Otherwise we simply drop everything if we consider instantaneous values since 'dequeue rate' will be zero for the first incoming packet and subsequently it repeats. An exponential weighted moving average over a fixed time interval would fit much better here. Please open a pull request if you are able to implement it, or also happy to hear if you have better ideas.

Many thanks for your replying. I am currently busy with my ongoing paper and work. Once I have finished them, I would be more than happy to continue addressing this issue and attempt to complete it.
