This document provides use case studies and network design
considerations for Multiprotocol Label Switching Transport Profile
(MPLS-TP).
In the recent years, MPLS-TP has emerged as the technology of choice
to meet the needs of transport evolution. Many service providers
(SPs) intend to replace SONET/SDH, TDM, ATM traditional transport
technologies with MPLS-TP, to achieve higher efficiency, lower
operational cost, while maintaining transport characteristics. The
use cases for MPLS-TP include Mobile backhaul, Metro Ethernet access
and aggregation, and packet optical transport. The design
considerations include operational experience, standards compliance,
technology maturity, end-to-end forwarding and OAM consistency,
compatibility with IP/MPLS networks, and multi-vendor
interoperability. The goal is to provide reliable, manageable, and
scalable transport solutions.
The unified MPLS strategy, using MPLS from core to aggregation and
access (e.g. IP/MPLS in the core, IP/MPLS or MPLS-TP in aggregation
and access) appear to be very attractive to many SPs. It streamlines
the operation, many help to reduce the overall complexity and

improve end-to-end convergence. It leverages the MPLS experience,
and enhances the ability to support revenue generating services.
