Abstract

   MPLS is being deployed deeper into operator networks, often to or
   past the access network node. Separately network access nodes such as
   PON 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 proposes the ICCP extension to support it.
