       Protocol for Forwarding Policy Configuration (FPC) in DMM
                     draft-ietf-dmm-fpc-cpdp-02.txt

Abstract

   This specification supports the separation of the Control-Plane for
   mobility- and session management from the Data-Plane.  The protocol
   semantics abstract the configuration of Data-Plane nodes and applies
   it 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 Data-
   Plane rules issued by the mobility Control-Plane.  The scope of the
   rules comprises traffic description 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.
