We have submitted a new draft to the LEDBAT WG and are planning to make a
short presentation at the LEDBAT WG and the ICCRG.
We are looking forward to all your comments.
The basic idea is to have an architecture framework, to enable the
standardization of the various mechanisms of a network friendly congestion
control such as available bandwidth estimation, flow control and congestion
detection separately. This could result in pluggable components that could
be used in the overall congestion control protocol/s. Though the draft is
intended for the LEDBAT WG, it could easily be extended to congestion
control protocols in general.
The Low Extra Delay Background Transport (LEDBAT) working group is
considering protocols for an alternative congestion control protocol
that enables a delay-insensitive networking application to minimize
the extra queueing delay it causes to other applications because of
additional queueing at the bottleneck, when these connections
carrying traffic for such applications attempt to use the available
This document proposes an architectural framework for LEDBAT
congestion control mechanisms, based on existing work on congestion
control protocols and the requirements of the LEDBAT working group.
The architectural framework consists of a LEDBAT-congestion control
(LEDBAT-CC) suite that provides flexibility in utilizing different
components for providing congestion control for transport connections
carrying delay-insensitive traffic. The LEDBAT-CC suite of protocols
is envisioned to support the multiple alternative mechanisms for
bandwidth estimation, congestion detection and indication and end-
system flow control to comprise a network friendly congestion
This document is inspired by the need to standardize the various
components that constitute the network friendly congestion control
protocol to avoid having to individually standardize a multitude of
distinct and monolithic solutions.
Feedback is welcome,
