MPLS Transport Profile (MPLS-TP) Identifiers
Abstract
This document specifies an initial set of identifiers to be used in
the Transport Profile of Multiprotocol Label Switching (MPLS-TP).
The MPLS-TP requirements (RFC 5654) require that the elements and
objects in an MPLS-TP environment are able to be configured and
managed without a control plane. In such an environment, many
conventions for defining identifiers are possible. This document
defines identifiers for MPLS-TP management and Operations,
Administration, and Maintenance (OAM) functions compatible with IP/
MPLS conventions.
This document is a product of a joint Internet Engineering Task Force
(IETF) / International Telecommunication Union Telecommunication
Standardization Sector (ITU-T) effort to include an MPLS Transport
Profile within the IETF MPLS and Pseudowire Emulation Edge-to-Edge
(PWE3) architectures to support the capabilities and functionalities
of a packet transport network as defined by the ITU-T.
