The IESG has approved the following document: - 'MPLS Egress Protection Framework' (draft-ietf-mpls-egress-protection-framework-07.txt) as Proposed Standard This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Alvaro Retana, Martin Vigoureux and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-mpls-egress-protection-framework/ Technical Summary This document specifies a fast reroute framework for protecting IP/ MPLS services and MPLS transport tunnels against egress node and egress link failures. For each type of egress failure, it defines the roles of point of local repair (PLR), protector, and backup egress router, and the procedures of establishing a bypass tunnel from a PLR to a protector. It describes the behaviors of these routers in handling an egress failure, including local repair on the PLR, and context based forwarding on the protector. The framework can be used to develop egress protection mechanisms to reduce traffic loss before global repair reacts to an egress failure and control plane protocols converge on the topology changes due to the egress failure. Working Group Summary This document is the convergence of several initiatives in the IETF and in the industry in general. The working group and more specifically the authors have invested a huge effort to converge on a single solution. Document Quality Aware of both implementations and deployments, as informed by one major European vendor. We have in addition started an Implementation Poll and the write-up will be updated as soon as more information is available. Personnel Who is the Document Shepherd for this document?
