Hello authors of the draft-ietf-dmm-5g-uplane-analysis-04.txt draft,

As I have said earlier 3GPP CT4 as concluded the user plane study that the draft is indirectly referring through the liaison statements in the intro section.
The study listed a number of issues why Srv6 is not considered suitable for the user plane. Please review 3GPP TR 29.892 and take that into account in the analysis.

I also would like to note that the Rel 16 is completed and 3GPP is working on Rel 17.

Therefore the sentences like " The study description mentions that the study would be based on
   Release 16 requirement while only Release 15 specifications has been
   available now.  However we believe that to provide adequate
   information for 3GPP, we need to clearly understand what the current
   user plane protocol is in Release 15, and architectural requirements
   for the user plane." is very weird considering that you are addressing completed Release.

I cannot understand why and what is the benefit of such.

Best regards
Hannu

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Distributed Mobility Management WG of the IETF.

        Title           : User Plane Protocol and Architectural Analysis on 3GPP 5G System
        Authors         : Shunsuke Homma
                          Takuya Miyasaka
                          Satoru Matsushima

Abstract:
   This document analyzes the mobile user plane protocol and the
   architecture specified in 3GPP 5G documents.  The analysis work is to
   clarify those specifications, extract protocol and architectural
   requirements and derive evaluation aspects for user plane protocols
   on IETF side.  This work is corresponding to the User Plane Protocol
   Study work on 3GPP side.
