Protocol for Forwarding Policy Configuration (FPC) in DMM
draft-ietf-dmm-fpc-cpdp-04.txt
Abstract
This document describes the solution of data-plane separation from
control-plane which enables a flexible mobility management system
using agent and client functions. To configure data-plane nodes and
functions, the data-plane is abstracted by an agent interface to the
client. The data-plane abstraction model is extensible in order to
support many different type of mobility management systems and data-
plane functions.
