Abstract:
As part of the Transport Profile for Multiprotocol Label Switching
(MPLS-TP) there is a requirement to support 1:n linear protection for
transport paths. This requirement is elaborated on in the MPLS-TP
Survivability Framework document [SurvivFwk]. The basic protocol for
linear protection was specified in the MPLS-TP Linear Protection
document [LinProt] but is limited to 1+1 and 1:1 protection. This
document extends the protocol defined there to address the additional
functionality necessary to support scenarios of a single protection
path preconfigured to provide protection of multiple transport paths
between two joint endpoints.
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 as
defined by the ITU-T.
