ITU-T Recommendation G.808.3 [G808.3] defines the generic aspects of a Shared Mesh Protection (SMP) mechanism, where the difference between SMP and Shared Mesh Restoration (SMR) is also identified. ITU-T Recommendation G.873.3 [G873.3] defines the protection switching operation and associated protocol for SMP at the Optical Data Unit (ODU) layer. RFC 7412 [RFC7412] provides requirements for any mechanism that would be used to implement SMP in a Multi-Protocol Label Switching - Transport Profile (MPLS-TP) network. This document updates RFC 4872 [RFC4872] to provide the extensions to the Generalized Multi-Protocol Label Switching (GMPLS) signaling to support the control of the shared mesh protection.
