Hi,
We just updated the draft to address the comments from Adrian and Stewart.
Main updates:
1. Addressed comments from Adrian (text of handling Path Segment on
intermediate nodes, editorial modifications, etc. ), and Adrian has confirmed.
Thanks a lot to Adrian.
2. Modify the text according to Stewart's comments. Stewart, please review the
update to see if it is ok to you. Many thanks.
3. Mach is quite busy recently, so he handed over the author to Cheng Li. Many
thanks to Mach, and welcome Cheng.
Please review the modifications, and any comments are welcome.
Thanks,
Weiqiang Cheng

A New Internet-Draft is available from the on-line Internet-Drafts
directories. This Internet-Draft is a work item of the Source Packet Routing
in Networking (SPRING) WG of the IETF.
Title : Path Segment in MPLS Based Segment Routing Network
Authors : Weiqiang Cheng

Filename : draft-ietf-spring-mpls-path-segment-09.txt
Pages : 12

Abstract:
A Segment Routing (SR) path is identified by an SR segment list.
Only the complete segment list can identify the end-to-end SR path,
and 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), bidirectional paths correlation, and
end-to-end 1+1 path protection.
In SR for MPLS data plane (SR-MPLS), the segment identifiers are
stripped from the packet through label popping as the packet transits
the network. This means that when a packet reaches the egress of the
SR path, it is not possible to determine on which SR path it
traversed the network.
This document defines a new type of segment that is referred to as
Path Segment, which is used to identify an SR path in an SR-MPLS
network. When used, it is inserted by the ingress node of the SR
path and immediately follows the last segment identifier in the
segment list of the SR path. The Path Segment is preserved until it
reaches the egress node for SR path identification and correlation.
