Protocol for Forwarding Policy Configuration (FPC) in DMM
draft-ietf-dmm-fpc-cpdp-12
Abstract
This document describes a way, called Forwarding Policy Configuration
(FPC) to manage the separation of data-plane and control-plane. FPC
defines a flexible mobility management system using FPC agent and FPC
client functions. A FPC agent provides an abstract interface to the
data-plane. The FPC client configures data-plane nodes by using the
functions and abstractions provided by the FPC agent for the data-
plane nodes. The data-plane abstractions presented in this document
are extensible in order to support many different types of mobility
management systems and data-plane functions.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
