Re: [DMM] Call for adoption of draft-hmm-dmm-5g-uplane-analysis-02 as DMM WG document

More precisely on the latter point,

>> Particularly the discussion around slicing is very speculative. And conclusion thereof that “The expected evaluation points from this aspect should be whether the candidate protocols can support to indicate a network slice in the UP packets.” Firstly, IETF doesn’t have any work on slicing, on the contrary. Secondly, the need for such indication in the 3GPP has been discussed in the ongoing 3GPP CT4 meeting this week with fully opposing views for such network slice indication. (Network slicing is supported in 3GPP Rel-15 already, and nothing new was defined in the user plane in Rel-15. There was no need for that!)

3GPP CT4 sees Network Slice consists of 5GC slice and transport slice while what's the transport slice is out of scope. As the 5GC control plane has maintained the context of 5GC slice, no identifier is needed in user plane to indicate *5GC slice*. Existing identifiers like VIDs, MPLS labels and IP addresses can be expected to indicate transport slices if it exists.

>> During IETF 102 and 103, the authors of the document, draft-hmm-dmm-5g-uplane-analysis.txt have provided the overview of this document. The chairs felt there is good amount of work that went into the document and the analysis has value. The document quality is very high. There was also generally good feedback and interest for the work from the community. We are therefore considering adopting this document as a DMM WG document, to be moved on Informational Standards track.  
>> 
>> There were also few concerns/comments on the 1.) Relevance of this document to 3GPP in the immediate time frame 2.) Archival Value of the document 3.) Target Audience  - IETF or 3GPP. 
>> On #3, there was also a view that the document should be restructured to make it IETF focussed.  With this background, we would like to ask the WG to provide some feedback on their interest for this work. Please provide substantial comments as why this should be adopted, or why it should not be adopted. If there is interest, and if there are no other concerns from AD/IESG/Others, then we may take up this work at some point.
