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 RFCs 4872 and 4873 to provide extensions for
Generalized Multi-Protocol Label Switching (GMPLS) signaling to
support the control of the SMP mechanism.
This document is a product of the Traffic Engineering Architecture and
Signaling Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
