The MPLS transport profile (MPLS-TP) is being standardized to enable
carrier-grade packet transport and complement converged packet
network deployments. One of the most attractive features of MPLS-TP
are OAM functions, which enable network operators or service
providers to provide various maintenance characteristics, such as
fault location, survivability, performance monitoring, and
preliminary or in-service measurements.
One of the most important mechanisms which are 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 fatal
drawbacks.
This document elaborates on the problem statement for the path
segment monitoring function. Moreover, this document requests to add
network objectives to solve or improve the issues and proposes to
consider a new improved method of segment monitoring.
This document is a product of a joint Internet Engineering Task Force
(IETF) / International Telecommunications Union Telecommunications
Standardization Sector (ITU-T) effort to include an MPLS Transport
Profile within the IETF MPLS and PWE3 architectures to support the
capabilities and functionalities of a packet transport network.
