[Codel] Fwd: [aqm] Document Action: 'On Queuing, Marking, and Dropping' to Informational RFC (draft-ietf-aqm-fq-implementation-05.txt)

[Dave Täht]

The IESG has approved the following document:
- 'On Queuing, Marking, and Dropping'
  (draft-ietf-aqm-fq-implementation-05.txt) as Informational RFC

This document is the product of the Active Queue Management and Packet
Scheduling Working Group.

The IESG contact persons are Spencer Dawkins and Martin Stiemerling.

Technical Summary

This note discusses implementation strategies for coupled queuing and
mark/drop algorithms. In the discussion of Active Queue Management,
there has been discussion of the coupling of queue management
(scheduling) algorithms with mark/drop (aqm) algorithms. This note is
Informational, intended to describe reasonable possibilities without
constraining outcomes.  This is not so much about "right" or "wrong" as
it is "what might be reasonable", and discusses several possible
implementation strategies.  Also, while queuing might be implemented in
almost any layer, specifically the document addresses queues that might
be used in the Differentiated Services Architecture, and are therefore
at or below the IP layer.

Working Group Summary

This document emerged to capture some of the discussions within the WG
around the combination of scheduling and AQM mechanisms, and to clarify
the discussion, as well as providing some guidance as to how to
implement such a combination.

Document Quality

The WG is actively looking at specific combined algorithms (e.g. FQ-
Codel), which have been widely recognized as being more effective than
either algorithm alone. There exists deployed code, as well as
simulation code for this particular combination, but many other
combinations, as described in the document, of different scheduling and
queue management algorithms are possible.
