The IESG has received a request from the Transport Area Working Group WG (tsvwg) to consider the following document: - 'Byte and Packet Congestion Notification' <draft-ietf-tsvwg-byte-pkt-congest-11.txt> as Best Current Practice The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-09-24. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document provides recommendations of best current practice for dropping or marking packets using any active queue management (AQM) algorithm, including random early detection (RED), BLUE, pre- congestion notification (PCN) and newer schemes such as CoDel and PIE. We give three strong recommendations: (1) packet size should be taken into account when transports detect and respond to congestion indications, (2) packet size should not be taken into account when network equipment creates congestion signals (marking, dropping), and therefore (3) in the specific case of RED, the byte-mode packet drop variant that drops fewer small packets should not be used. This memo updates RFC 2309 to deprecate deliberate preferential treatment of small packets in AQM algorithms. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-tsvwg-byte-pkt-congest/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-tsvwg-byte-pkt-congest/ballot/ No IPR declarations have been submitted directly on this I-D.
