Multi-Chassis Passive Optical Network (MC-PON) Protection in MPLS
Abstract
Multiprotocol Label Switching (MPLS) is being extended to the edge of
operator networks including the network access nodes. 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. Multihoming support is needed on the
MPLS-enabled PON OLT to provide resiliency for provided services.
This document describes the Multi-Chassis PON (MC-PON) protection
architecture in MPLS and also specifies the Inter-Chassis
Communication Protocol (ICCP) extension to support it.
