Abstract

This document describes the application of MPLS multi-segmentpseudowires (MS-PWs) in a dual-technology environment comprising aPassive Optical Network (PON) and an MPLS Packet Switched Network(PSN).

PON technology may be used in mobile backhaul networks to support theend segments closest to the aggregation devices. In these cases,there may be a very large number of pseudowire (PW) TerminatingProvider Edge (T-PE) nodes. The MPLS control plane could be used toprovision these end segments, but support for the necessary protocolswould complicate the management of the T-PEs and would significantlyincrease their expense. Alternatively, static, or management plane,configuration could be used to configure the end segments, but thevery large number of such segments in a PON places a very heavyburden on the network manager.

This document describes how to set up the end segment of an end-to-end MPLS PW over a Gigabit-capable Passive Optical Network (G-PON) or10 Gigabit-capable Passive Optical Network (XG-PON) using the G-PONand XG-PON management protocol, Optical Network TerminationManagement and Control Interface (OMCI). This simplifies and speedsup PW provisioning compared with manual configuration.

This document also shows how an MS-PW may be constructed from an endsegment supported over a PON, and switched to one or more segmentssupported over an MPLS PSN. This document is not an Internet Standards Track specification; it is published for informational purposes.
