Abstract:
   The MPLS transport profile (MPLS-TP) has been standardized to enable
   carrier-grade packet transport and to complement converged packet
   network deployments.  The most attractive features of MPLS-TP are the
   OAM functions.  These functions enable maintenance tools that may be
   exploited by network operators and service providers for fault
   location, survivability, performance monitoring, in-service and out-
   of-service measurements.

   One of the most important mechanisms that is common for transport
   network operation is fault localisation.  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 activated only between end points.  However, the current
   approach defined for MPLS-TP of segment monitoring has some
   drawbacks.  This document elaborates on the problem statement for the
   Sub-path Maintenance Elements (SPMEs) which provide monitoring of a
   segment of a set of transport paths (LSPs or MS-PWs).  Based on the
   identified problems, this document provides considerations for the
   specification of new requirements to consider a new improved
   mechanism for hitless transport path segment monitoring to be named
   Enhanced Path Segment Monitoring (EPSM).
