[Cerowrt-devel] [OpenWrt-Devel] [RFC PATCH] packages: Smart Queue Management for AQM Packet Scheduling and Qos from CeroWrt

Thu Feb 12 21:02:46 EST 2015

Sebastian , Dave,
Thanks for these instructions.
I just finished a round of 3 months testing this setup on a couple of MyNet
N750 ( AR71xx based ) in several locations.
The feedback from users is very positive and encouraging - Most of them say
that they feel the networks behave a lot snappier than before [ 7.5Mbps Up/
1Mbps Down].

All I had to do was install the 3 packages over BB 14.07 :
ip-full from the OpenWRT BB repository
and luci-app-sqm + sam-scripts from the CeroWRT repository.

Will the later two packages ever make it to the main OpenWRT package list?
or there other packages that on the main OpenWRT distribution that can be
used to provide this functionality? ( the 2 CeroWRT packages above make
really simple to setup ).

Regards,
Luis Garcia
