TCP measures RTT;
one could create a global histogram of all measured RTTs by TCP (whenever a
valid measurement is taken), and export that with "netstat -sp tcp"... Of
course, vastly different paths would be gobbled up together, but when
investigating specific paths, that should be go
Hi Ketan -
It is possible for good architects to simplify rather than to ramify. It takes
clear understanding of the system as a whole, a unifying perspective, and a
goal to make the system work extremely well and simply.
One of the key insights into how to do this was the choice of feature

Ah, but fq_codel *does* cope with that sort of problem relatively well. It
doesn't need to distinguish types of flows, just f
I won't deny that there are problems with delay based congestion control,
but at least some of the same problems also apply to AQM.
In the presence of greedy UDP flows, AQM would highly bias those flows.
Sure, the more packets a flow sends, the more it will have it's packets
dropped. But only TCP
