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 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).}, }
