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 shared mesh protection (SMP) at the optical data unit (ODU) layer. This document updates RFC 4872 to provide the extensions to the Generalized Multi-Protocol Label Switching (GMPLS) signaling to support the control of the shared mesh protection.
