    abstract =  {This document introduces a mechanism to specify a Segment Routing (SR) policy, as a collection of SR candidate paths. An SR policy is identified by \textless{}headend, color, end-point\textgreater{} tuple. An SR policy can contain one or more candidate paths where each candidate path is identified in PCEP via an PLSP-ID. This document proposes extension to PCEP to support association among candidate paths of a given SR policy. The mechanism proposed in this document is applicable to both MPLS and IPv6 data planes of SR.},
