Abstract:
   The MPLS transport profile (MPLS-TP) has been standardized to enable
   carrier-grade packet transport and complement converged packet
   network deployments.  Among the most attractive features of MPLS-TP
   there are OAM functions, which enable network operators or service
   providers to provide various maintenance characteristics, such as
   fault location, survivability, performance monitoring and in-service/
   out of service measurements.

   One of the most important mechanisms which is common for transport
   network operation is fault location.  A segment monitoring function
   of a transport path is effective in terms of extension of the
   maintenance work and indispensable particularly when the OAM function
   is effective only between end points.  However, the current approach
   defined for MPLS-TP for the segment monitoring (SPME) has some
   drawbacks.  This document elaborates on the problem statement for the
   Sub-path Maintenance Elements (SPMEs) which provides monitoring of a
   portion of a set of transport paths (LSPs or MS-PWs).  Based on the
   problems, this document specifies new requirements to consider a new
   improved mechanism of hitless transport path segment monitoring named
   Enhanced Path Segment Monitoring (EPSM).
