Hi WG and Chairs,

We have updated the draft-li-pce-sr-path-segment. Just some editorial updates and personnel changes.

Since the architecture document draft-ietf-spring-mpls-path-segment-00 has been adopted in the SPRING WG,  and the content of this document has been mature and stable, we think it is a good candidate for WG adoption now, so we request for WG adoption call for this document.

Recent Modifications:
* P-flag：Path Segment Allocation flag -> PCE allocation Flag, which can be reused by many other resource request, like binding SID. 
                    The change has been mentioned in PCECC drafts already. Update to sync up.
* MSD: adding some text to describe MSD consideration in path segment allocation. 
* Refs sync up
* Fixed some nits.
* Diff: https://www.ietf.org/rfcdiff?url2=draft-li-pce-sr-path-segment-04

Personnel Changes: 
* Added Quan Xiong from ZTE as a new co-author in contributor section.
* Also, moved Dhruv to the contributor section.

Best Regards,
Cheng, on behalf of authors.

Abstract:
   The Path Computation Element (PCE) provides path computation
   functions in support of traffic engineering in Multiprotocol Label
   Switching (MPLS) and Generalized MPLS (GMPLS) networks.

   The Source Packet Routing in Networking (SPRING) architecture
   describes how Segment Routing (SR) can be used to steer packets
   through an IPv6 or MPLS network using the source routing paradigm.  A
   Segment Routed Path can be derived from a variety of mechanisms,
   including an IGP Shortest Path Tree (SPT), explicit configuration, or
   a Path Computation Element (PCE).

   Path identification is needed for several use cases such as
   performance measurement in Segment Routing (SR) network.  This
   document specifies extensions to the Path Computation Element
   Protocol (PCEP) to support requesting, replying, reporting and
   updating the Path Segment ID (Path SID) between PCEP speakers.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
