The IESG has approved the following document: - 'Detecting Multi-Protocol Label Switched (MPLS) Data Plane Failures' (draft-ietf-mpls-rfc4379bis-09.txt) as Proposed Standard This document is the product of the Multiprotocol Label Switching 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-mpls-rfc4379bis/ Technical Summary The document specifies an efficient mechanism to detect data plane failures in MPLS data plane failures, i.e. failures of an LSPs. The specification consists of two parts: - information carried in an MPLS "echo request" and "echo reply" for the purposes of fault detection and isolation - mechanisms for reliably sending the echo reply messages. Working Group Summary This has been a major work performed by a dedicated to team and the work has regularly been reported in f2f meetings and on the working group mailing list. There is a wide spread recognition that there is a need to consolidate the LSP Ping specification (a widely deployed technology) into a smaller number of documents. The support for publishing this document is solid. Document Quality RFC 4379 is one of the most widely implemented and deployed MPLS specifications, the documents that are being obsoleted are also widely implemented and well deployed. No specific reviews, other than what has been done within the working group, are necessary. Personnel Who is the Document Shepherd for this document?
