Abstract
A method implemented in a Path Computation Element (PCE) or Software Defined Networking (SDN) controller includes computing a path for a service in a Segment Routing network where the path includes an explicit list of routers in the Segment Routing network; determining a Segment Identifier (SID) list for the path; an signaling the explicit list and the SID list to a head-end router for the service. The SID list can be compressed where it does not include a SID for each of the routers in the explicit. The method can further include monitoring Traffic Engineering characteristics in the Segment Routing network based on knowing the service is on the explicit list of routers.
