MPLS Transport Profile (MPLS-TP) Linear Protection
Abstract
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 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 addresses the functionality described in the MPLS-TP
Survivability Framework document (RFC 6372) and defines a protocol
that may be used to fulfill the function of the Protection State
Coordination for linear protection, as described in that document.
