A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Multiprotocol Label Switching of the IETF. Title : Hitless path segment monitoring Authors : Alessandro D'Alessandro Loa Andersson Satoshi Ueno Kaoru Arai Yoshinori Koike Filename : draft-ietf-mpls-tp-temporal-hitless-psm-12.txt Pages : 16 Date : 2017-02-01 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 IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-mpls-tp-temporal-hitless-psm/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-ietf-mpls-tp-temporal-hitless-psm-12 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-mpls-tp-temporal-hitless-psm-12 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
