The IESG has approved the following document: - 'Extensions to Resource Reservation Protocol For Fast Reroute of Traffic Engineering GMPLS LSPs' (draft-ietf-teas-gmpls-lsp-fastreroute-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, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-teas-gmpls-lsp-fastreroute/ Technical Summary This document defines Resource Reservation Protocol - Traffic Engineering (RSVP-TE) signaling extensions to support Fast Reroute (FRR) of Packet Switched Capable (PSC) Generalized Multi-Protocol Label Switching (GMPLS) Label Switched Paths (LSPs). These signaling extensions allow the coordination of a bidirectional bypass tunnel assignment protecting a common facility in both forward and reverse directions of a co-routed bidirectional LSP. In addition, these extensions enable the re-direction of bidirectional traffic onto bypass tunnels that ensure co-routedness of data paths in the forward and reverse directions after FRR and avoid RSVP soft-state timeout in control-plane. Working Group Summary This document moved from the CCAMP WG to TEAS WG as part of the routing WG changes. There was some serious debate regarding the object-format/procedures defined for co-ordinating bidirectional bypass tunnel assignment between the downstream and upstream PLRs. All concerns raised in regard to this have been addressed by the authors. The document went through three WG Last Calls before being deemed “publication-request” ready as substantial comments were raised during the first and second Last Calls. Document Quality The base (G)MPLS RSVP protocol has been implemented. The procedures discussed in this document are compatible with earlier implementations. While there have been no public statements on implementation, the authors are from multiple vendors, and implementation is expected. Personnel Who is the Document Shepherd for this document?
