<div dir="ltr">and to clarify more about what else was discussed, it seems to me some of us tend to correspond and relate the notion of "good queue" vs. "bad queue" used by KN+VJ ACM queue paper to my question on "good bursts". While they likely to be correlated (I have no argument on this now), the notion of "good burst" goes beyond the "good queue" defined in that paper. Based on their definition a good queue is a queue that minimizes the standing queue (or gets rid of it entirely) while allowing a certain amount of (sub-RTT? typical 100 ms) bursts while avoiding the link to get under-utilized. That notion (again, I have no argument on its correctness for now) is different from my question on "good bursts" which means that: once we manage to get rid of the standing queue, what types/sizes of bursts I should let the AQM X to protect/handle?<div>

The mission of dealing with packet bursts in addition to the task of keeping the standing queue very low or minimal is part of an "AQM evaluation criteria" I envision.

<br>
</div>I can't comment on what he means. I took the question as "what should a system that is in receipt of what it might consider a 'burst', and more especially a 'good burst', to be?"<br>
<br>
I don't know that a sending transport (which is to be distinguished from the queueing arrangement in that same system) or a receiving system *has* a definition of a "good" or "bad" burst. The one is sending data, which in the context of y two examples might be a good or bad idea, and the other is receiving it. From the receiver's perspective, the data either arrived or it didn't; if it arrived, there is no real argument for not delivering it to its application...<br>
