Abstract
Segment Identifier (SID) list compression includes receiving a calculated path in a Segment Routing network from a headend node to an end node; utilizing a compression approach to determine a segment list that, when expanded, matches the calculated path, wherein each segment in the segment list is identified by a SID, and wherein the SID is selected from any of a base topology in the Segment Routing network and any Flexible Algorithm (Flex-Algo) topologies in the Segment Routing network; and providing the segment list to the headend node. The SID list compression can further include, prior to the receiving, calculating the calculated path from the headend node to the end node based one or more constraints, wherein the SIDs are selected after the calculated path is determined without regard to any purpose of the any Flex-Algo topologies.
