Subject: [Cake] an "evil" queue class?
Date: Thu, 11 Jun 2015 18:08:59 -0700 [thread overview]
Message-ID: <CAA93jw55BT-xhb=SoWCY25DFW46UiRfAQKZy=E-P0y-39sw6ew@mail.gmail.com> (raw)
An evil flow is one that is consistently not responding to drops, and
occupying a vastly disproportionate amount of queue space compared to
the other flows.
The HHF qdisc has a concept like this in it, but what I have in mind
is simpler.
Somewhat related, we can make cake_drop be less cpu intensive and more
deterministic with a small cache of the top (say, 3) "offenders"
maintained at either dequeue or enqueue time.
(ideas based on pounding codel flat with iperf -u and watching it stay
pounded flat for a long period of time)
