GMPLS Signaling Extensions for Shared Mesh Protection
draft-ietf-teas-gmpls-signaling-smp-05
Abstract
ITU-T Recommendation G.808.3 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 defines the protection switching operation and
associated protocol for SMP at the Optical Data Unit (ODU) layer.
RFC 7412 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 to provide the extensions to the
Generalized Multi-Protocol Label Switching (GMPLS) signaling to
support the control of the SMP.
