Technical Summary
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.
Working Group Summary
There was notable debate on how pre-emption is handled in the Shared
Mesh Protection signaling procedures. The authors addressed all of these
concerns by adding relevant text to the document.
Document Quality
The document has been discussed and reviewed thoroughly by the WG. While
there have been no official statements on implementation of this
new framework, some of the authors are from a vendor, and implementation
is expected.
