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, 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.
