       Protocol for Forwarding Policy Configuration (FPC) in DMM
                     draft-ietf-dmm-fpc-cpdp-00.txt

Abstract

   The specification as per this document supports the separation of the
   Control-Plane for mobility- and session management from the actual
   Data-Plane.  The protocol semantics abstract from the actual details
   for the configuration of Data-Plane nodes and apply between a Client
   function, which is used by an application of the mobility Control-
   Plane, and an Agent function, which is associated with the
   configuration of Data-Plane nodes according to the policies issued by
   the mobility Control-Plane.  The scope of the policies comprises
   forwarding rules and treatment of packets in terms of encapsulation,
   IP address re-writing and QoS.  Additional protocol semantics are
   described to support the maintenance of the Data-Plane path.

1.  Introduction

   One objective of the Distributed Mobility Management (DMM) WG is the
   separation of the mobility management Control- and Data-Plane to
   enable flexible deployment, such as decentralized provisioning of
   Data-Plane nodes (DPN).  Data-Plane nodes can be configured to
   function as anchor for a registered Mobile Node's (MN) traffic,
