Abstract:

   A Segment Routing (SR) path is identified by an SR segment list.  A
   sub-set of segments from the segment list cannot be leveraged to
   distinguish one SR path from another as they may be partially
   congruent.  SR path identification is a pre-requisite for various
   use-cases such as Performance Measurement (PM), and end-to-end 1+1
   path protection.

   In SR for MPLS data plane (SR-MPLS), an Egress node cannot determine
   on which SR path a packet traversed the network from the label stack
   because the segment identifiers are removed from the label stack as
   the packet transits the network.

   This document defines Path Segment Identifier(PSID) to identify an SR
   path on the egress node of the path.
