Network Management Requirements for MPLS-based Transport Networks
Abstract
This document specifies the requirements for the management of
equipment used in networks supporting an MPLS Transport Profile
(MPLS-TP). The requirements are defined for specification of
network management aspects of protocol mechanisms and procedures
that constitute the building blocks out of which the MPLS
Transport Profile is constructed. That is, these requirements
indicate what management capabilities need to be available in
MPLS for use in managing the MPLS-TP. This document is intended
to identify essential network management capabilities, not to
specify what functions any particular MPLS implementation
supports.
