Re: [aqm] Comments on draft-ietf-aqm-eval-guidelines-01?
Hi, Bi-directional traffic is mentioned in section 3.1 Topology and 4.5 Traffic Mix, but not further detailed. I suggest to add at least one scenario in section 4.5, where both directions are congested at the same time, e.g. two or more counter propagating bulk TCP transfers. Only in this scenario the returning ACK packets undergo a reasonable queuing delay (and jitter) from the opposite direction queue. If I'm right, Dave Taht repeatedly mentioned that scenario as critical. And he is right, I tried it out.

Hi all Any comments on the newly submitted update as draft-ietf-aqm-eval-guidelines-01 is welcomed. In the new version, we have tried to address the issues brought up on the ML as well as the feedback we received at the IETF-91 and have tried to incorporate them all. We have also clarified several issues in the text making it more straightforward and less ambiguous with regards to the guidelines and scenarios. We would like to have this document discussed on the ML preferably before the 9th March cut-off date as well as during the period prior to IETF-92.

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Active Queue Management and Packet Scheduling Working Group of the IETF. Title : The Benefits to Applications of using Explicit Congestion Notification (ECN) Authors : Michael Welzl Godred Fairhurst Filename: draft-welzl-ecn-benefits-02.txt Pages : 11 Date: 2015-03-09 Abstract: This document describes the potential benefits to applications when they enable Explicit Congestion Notification (ECN). It outlines the principal gains in terms of increased throughput, reduced delay and other benefits when ECN is used over network paths that include equipment that supports ECN-marking. The focus of this document is on usage of ECN, not its implementation in hosts, routers and other network devices.
