Subject: [PATCH 0/2] HTB scheduler HTB_HYSTERESIS modifications
Date: Tue, 03 Jun 2008 16:03:23 +0200 [thread overview]
Message-ID: <1212501803.13164.27.camel@localhost.localdomain> (raw)
This patch set modifies the HTB schedulers hysteresis mode. The HTB
hysteresis is a hack to reduce the CPU load, it introduces significant
jitter, enough to disturbe VoIP quality on e.g. ADSL.
The first patch changes HTB_HYSTERESIS to default off.
The second patch Change HTB_HYSTERESIS to a runtime parameter
htb_hysteresis, adjustable via
sys/module/sch_htb/parameters/htb_hysteresis.
For details about my measurements see masters thesis
(http://www.adsl-optimizer.dk/thesis/), chapter 7, section 7.3.1,
page 69-70.
