Abstract

   While MPLS is deployed further and further to the access network, a
   converging network edge point which provides both MPLS and PON access
   capability appears. To provide resiliency for its services, multi-
   homing is needed to support PON access in MPLS. This document
   describes the multi-chassis PON protection architecture in MPLS and
   also proposes the ICCP extension to support it.

3. Introduction

   MPLS is extending further and further to the edge of networks, for
   example, the seamless MPLS use cases as described in [SEAMLESS], and
   the MS-PW with PON access use case as described in [RFC6456], all
   show that MPLS is approaching the access networks.
