Multiprotocol Label Switching (MPLS) is being extended to the edge of operator networks, as is described in the multi-segment pseudowires (PWs) with Passive Optical Network (PON) access use case [RFC6456]. Combining MPLS with Optical Line Termination (OLT) access further facilitates a low-cost, multi-service convergence.

Multi-Chassis Passive Optical Network (MC-PON) Protection in MPLS
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.
