Dear Wesley, Dear All, First of all our feedback regarding different "re-entering dropping state" in the document and in the Linux implementation (http://www.ietf.org/mail-archive/web/aqm/current/msg01686.html) was not addressed. As FQ-CoDel relies on CoDel, this issue is also (partly)

Dear all, Apologies for the long delay. I have review the latest version of the draft. In my opinion the document still needs a detailed review about the representation (the text): the structure of the document would make more sense if the information in section 2, 3, and 4 would appear in

Dear Jonathan, Thanks for your extensive answer. If you could comment on a couple more things: 1. in Cake, count saturates at 2^32-1, am I right (https://github.com/dtaht/sch_cake/blob/master/codel5.h#L352). could it make sense to saturate count when interval/sqrt(count) and

Hello all, Here are my thoughts about interaction of AQM and fair-queueing system. I think I will start with a figure. I have started a tcp flow with netperf, and 15 seconds later unresponsive UDP flow with iperf with a send rate a little bit above bottleneck link capacity. Both flows run

Hello all, If I understood the code correctly, in fq_pie there is a single PIE instance that controls all fq queues. In contrast in fq_codel there is a separate instance of codel for each queue. Is this the case? If it is, doesn't it contradict with original idea of fq_something where each
