A New Internet-Draft is available from the on-line Internet-Drafts directories.
  This draft is a work item of the Congestion Exposure Working Group of the IETF.

         Title           : Congestion Exposure (ConEx) Concepts and Abstract Mechanism
         Authors         : Matt Mathis
                           Bob Briscoe
	Filename        : draft-ietf-conex-abstract-mech-11.txt

    This document describes an abstract mechanism by which senders inform
    the network about the congestion encountered by packets earlier in
    the same flow.  Today, network elements at any layer may signal
    congestion to the receiver by dropping packets or by ECN markings,
    and the receiver passes this information back to the sender in
    transport-layer feedback.  The mechanism described here enables the
    sender to also relay this congestion information back into the
    network in-band at the IP layer, such that the total amount of
    congestion from all elements on the path is revealed to all IP
    elements along the path, where it could, for example, be used to
    provide input to traffic management.  This mechanism is called
    congestion exposure or ConEx.  The companion document "ConEx Concepts
    and Use Cases" provides the entry-point to the set of ConEx
