A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : A Mechanism for ECN Path Probing and Fallback Author(s) : Mirja Kuehlewind Brian Trammell Filename : draft-kuehlewind-tcpm-ecn-fallback-00.txt Pages : 5 Date : 2013-07-03 Abstract: Explicit Congestion Notification (ECN) is a TCP/IP extension that is widely implemented but hardly used due to the perceived unusablilty of ECN on many paths through the Internet caused by ECN-ignorant routers and middleboxes. This document specifies an ECN probing and fall-back mechanism in case ECN has be successfully negotiated between two connection endpoints, but might not be usable on the path.
