A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the TCP Maintenance and Minor Extensions WG of the IETF. Title : TCP Alternative Backoff with ECN (ABE) Authors : Naeem Khademi Michael Welzl Grenville Armitage Godred Fairhurst Filename : draft-ietf-tcpm-alternativebackoff-ecn-05.txt Pages : 13 Date : 2017-12-11 Abstract: Recent Active Queue Management (AQM) mechanisms allow for burst tolerance while enforcing short queues to minimise the time that packets spend enqueued at a bottleneck. This can cause noticeable performance degradation for TCP connections traversing such a bottleneck, especially if there are only a few flows or their bandwidth-delay-product is large. An Explicit Congestion Notification (ECN) signal indicates that an AQM mechanism is used at the bottleneck, and therefore the bottleneck network queue is likely to be short. This document therefore proposes an update to RFC3168, which changes the TCP sender-side ECN reaction in congestion avoidance to reduce the Congestion Window (cwnd) by a smaller amount than the congestion control algorithm's reaction to inferred packet loss.
