             MPLS-TP Applicability; Use Cases and Design  
             draft-ietf-mpls-tp-use-cases-and-design-04.txt

Abstract

   This document provides applicability, use case studies and network
   design considerations for the Multiprotocol Label Switching Transport
   Profile (MPLS-TP). The use cases include Metro Ethernet access and
   aggregation transport, Mobile backhaul, and packet optical transport.
