           Mobile Communication Congestion Exposure Scenario
                       draft-ietf-conex-mobile-04

Abstract

   This memo describes a mobile communications use case for congestion
   exposure (ConEx) with a particular focus on those mobile
   communication networks that are architecturally similar to the 3GPP
   Evolved Packet System (EPS).  The draft provides a brief overview of
   the architecture of these networks (both access and core networks),
   current QoS mechanisms and then discusses how congestion exposure
   concepts could be applied.  Based on this, this memo suggests a set
   of requirements for ConEx mechanisms that particularly apply to these
   mobile networks.

Status of this Memo

   This Internet-Draft is submitted in full conformance with the
