Abstract:
The MPLS transport profile (MPLS-TP) is being standardized to enable
carrier-grade packet transport and complement converged packet
network deployments. Among 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 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 fatal 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.
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.
