sqm-scripts: Smart Queue Management - experimental QoS
sqm-scripts is a new QoS system from Cerowrt / Bufferbloat.
I have tested it in my own community build.
More info at:
http://www.bufferbloat.net/projects/cerowrt/wiki/Smart_Queue_Management
http://www.bufferbloat.net/projects/cerowrt/wiki/Setting_up_SQM_for_CeroWrt_310
Dave Täht submitted this first via openwrt-devel mailing list in March 2014,
but that was not picked up before the switch to Github:
http://patchwork.openwrt.org/patch/5078/
Original code used as the base:
8ce2936110
I have modified:
- set the default interface to be eth1, like the Openwrt default.
- modified config to hide some of the advanced options by default
- beautified Makefile a bit
- added Toke Høiland-Jørgensen <toke@toke.dk> as the maintainer, as discussed
in https://github.com/dtaht/ceropackages-3.10/issues/8#issuecomment-59215905

# Comments
|

|
# This does the right thing with ipv6 traffic.
|
||||||
|
# It also tries to leverage diffserv to some sane extent. In particular,
|
||||||
|
# the 'priority' queue is limited to 33% of the total, so EF, and IMM traffic
|
||||||
|
# cannot starve other types. The rfc suggested 30%. 30% is probably
|
||||||
|
# a lot in today's world.
|
||||||
|
|
||||||
|
# Flaws
|
||||||
|
# Many!

# Comments
|
||||||
|
# This does the right thing with ipv6 traffic.
|
||||||
|
# It also tries to leverage diffserv to some sane extent. In particular,
|
||||||
|
# the 'priority' queue is limited to 33% of the total, so EF, and IMM traffic
|
||||||
|
# cannot starve other types. The rfc suggested 30%. 30% is probably
|
||||||
|
# a lot in today's world.
|
||||||
|
|
||||||
|
# Flaws
|
||||||
|
# Many!
