Re: [aqm] fixing bufferbloat on bigpond cable...

[Dave Taht <[e-mail]>]

Sorry, didn't read the thread closely. I made a few suggestions on
that person's gist, as you probably also have downstream bufferbloat
as well, which you can fix (on the edgerouter and openwrt) at speeds
up to 60mbit on those weak cpus using the user-supplied edgerouter gui
for the ingress stuff. The code for doing inbound shaping also is not
that much harder, a simple example for that is in the "ingress"
section on the gentoo wiki here:
http://wiki.gentoo.org/wiki/Traffic_shaping

(sqm-scripts in openwrt and other linuxen has the logic for this also built-in)

It is grand to have helped you out a bit. Thx for all the work on
http/2! How about some ecn? ;)
