The IESG has approved the following document: - 'GMPLS Signaling Extensions for Shared Mesh Protection' (draft-ietf-teas-gmpls-signaling-smp-12.txt) as Proposed Standard This document is the product of the Traffic Engineering Architecture and Signaling Working Group. The IESG contact persons are Alvaro Retana, Andrew Alston and John Scudder. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-teas-gmpls-signaling-smp/ 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. Personnel > Who is the Document Shepherd?
