The IESG has received a request from the Source Packet Routing in Networking WG (spring) to consider the following document: - 'Path Segment in MPLS Based Segment Routing Network' <draft-ietf-spring-mpls-path-segment-16.txt> as Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the last-c...@ietf.org mailing lists by 2023-10-26. Exceptionally, comments may be sent to i...@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract A Segment Routing (SR) path is identified by an SR segment list. A sub-set of segments from the segment list cannot 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 to identify an SR path on the egress node of the path.
