                MPLS-TP Applicability; Use Cases and Design 
              draft-ietf-mpls-tp-use-cases-and-design-01.txt 
    
Abstract 
 
    
   This document provides applicability, 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 
   for the new generation of packet transport. Many service providers 
   (SPs) are working to replace the legacy transport technologies, e.g. 
   SONET/SDH, TDM, and ATM technologies, with MPLS-TP for packet 
   transport, in order to achieve higher efficiency, lower operational 
   cost, while maintaining transport characteristics.  
    
   The use cases for MPLS-TP include Metro Ethernet access and 
   aggregation, Mobile backhaul, and packet optical transport. The 
   design considerations discussed in this documents ranging from 
   operational experience; standards compliance; technology maturity; 
   end-to-end forwarding and OAM consistency; compatibility with 
   IP/MPLS networks; multi-vendor interoperability; and optimization 
   vs. simplicity design trade off discussion. The general design 
   principle is to provide reliable, manageable, and scalable transport 
   solutions.
