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.
