Abstract:
The "persistently full buffer" problem has been discussed in the IETF
community since the early 80's [RFC896]. The IRTF's End-to-End
Working Group called for the deployment of active queue management
(AQM) to solve the problem in 1998 [RFC2309]. Despite the awareness,
the problem has only gotten worse as Moore's Law growth in memory
density fueled an exponential increase in buffer pool size. Efforts
to deploy AQM have been frustrated by difficult configuration and
negative impact on network utilization. This problem, recently
christened "bufferbloat", [TSVBB2011] [BB2011] has become
increasingly important throughout the Internet but particularly at
the consumer edge.
This document describes a general framework called CoDel (Controlled
Delay) [CODEL2012] that controls bufferbloat-generated excess delay
in modern networking environments. CoDel consists of an estimator, a
setpoint, and a control loop. It requires no configuration in normal
Internet deployments. CoDel comprises some major technical
innovations and has been made available as open source so that the
framework can be applied by the community to a range of problems. It
has been implemented in Linux (and available in the Linux
distribution) and deployed in some networks at the consumer edge. In
addition, the framework has been successfully applied in other ways.
