Ok. Then, if the average packet(qave) does not exceed the threshhold, that is, the
packet has not been dropped, it will be enqueued into the physical queue, right?
So we can't see the different process of scheduling packets which are from
different kinds of traffic, we just know which packet might be dropped, right?

what does "the more aggressive set of parameters" mean? The parameters to Gred?
Thank you very much!
