Abstract Abstract
A Segment Routing (SR) policy is a set of candidate SR paths A Segment Routing (SR) policy is a set of candidate SR paths
consisting of one or more segment lists with necessary path consisting of one or more segment lists with necessary path
attributes. For each SR path, it may also have its own path attributes. For each SR path, it may also have its own path
attributes, and Path Segment is one of them. A Path Segment is attributes, and Path Segment is one of them. A Path Segment is
defined to identify an SR path, which can be used for performance defined to identify an SR path, which can be used for performance
measurement, path correlation, and end-2-end path protection. Path measurement, path correlation, and end-2-end path protection. Path
Segment can be also used to correlate two unidirectional SR paths Segment can be also used to correlate two unidirectional SR paths
