This document specifies an architectural framework for the
application of Multiprotocol Label Switching (MPLS) to the
construction of packet-switched transport networks. It describes a
common set of protocol functions -- the MPLS Transport Profile
(MPLS-TP) -- that supports the operational models and capabilities
typical of such networks, including signaled or explicitly
provisioned bidirectional connection-oriented paths, protection and
restoration mechanisms, comprehensive Operations, Administration, and
Maintenance (OAM) functions, and network operation in the absence of
a dynamic control plane or IP forwarding support. Some of these
functions are defined in existing MPLS specifications, while others
require extensions to existing specifications to meet the
requirements of the MPLS-TP.
This document defines the subset of the MPLS-TP applicable in general
and to point-to-point transport paths. The remaining subset,
applicable specifically to point-to-multipoint transport paths, is
outside the scope of this document.
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. This document
is not an Internet Standards Track specification; it is published for
informational purposes.
This document is a product of the Multiprotocol Label Switching Working Group of the IETF.
