       Multi-chassis Passive Optical Network (PON) Protection in MPLS
                       draft-ietf-pals-mc-pon-02.txt

Abstract

   MPLS is being deployed deeper into operator networks, often to or
   past the access network node. Separately network access nodes such
   as Passive Optical Network (PON) Optical Line Terminations (OLTs)
   have evolved to support first-mile access protection, where one or
   more physical OLTs provide first-mile diversity to the customer edge.
   Multi-homing support is needed on the MPLS-enabled PON OLT to
   provide resiliency for provided services.  This document describes
   the multi-chassis PON protection architecture in MPLS and also
   specifies the Inter-Chassis Communication Protocol (ICCP) extension
   to support it.
