The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'Hitless path segment monitoring' <draft-ietf-mpls-tp-temporal-hitless-psm-12.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-03-03. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract One of the most important OAM capabilities for transport network operation is fault localisation. An in-service, on-demand segment monitoring function of a transport path is indispensable, particularly when the service monitoring function is activated only between end points. However, the current segment monitoring approach defined for MPLS (including the transport profile (MPLS-TP)) in RFC 6371 [RFC6371] has drawbacks. This document provides an analysis of the existing MPLS-TP OAM mechanisms for the path segment monitoring and provides requirements to guide the development of new OAM tools to support a Hitless Path Segment Monitoring (HPSM). The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-mpls-tp-temporal-hitless-psm/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-mpls-tp-temporal-hitless-psm/ballot/ No IPR declarations have been submitted directly on this I-D.
