Subject: Re: Time in Queue, bufferbloat, and... our accidentally
 interplanetary network

Hi,

For what it's worth, I've also been tinkering with time-in-queue for
the wifi queue management in FreeBSD. I don't have anything public
yet. What I have done actually seems to work quite well, when doing TX
queue time-in-queue management. (I'm ignoring RX queue management for
now.)

Yes, I think a weighted random drop with both time-in-queue and queue
depth would work well. I haven't sat down to model what it'd look like
given some traffic profiles.

I'll be sure to post some patches and results when I have them. :)

Adrian
