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,
