Re: [DMM] Adoption call for I.D.: draft-zzhang-dmm-mup-evolution-06 (Mobile User Plane Evolution)

Hi,

Thanks, Tianji for presenting in IETF117 and requesting adoption in the presentation and here.

As a co-author, I obviously agree with what Tianji said here and want to see it adopted. I am sure other co-authors share the same view even though they did not explicitly echo “agree/support as co-author” 😊

We appreciate that DMM provided a venue for us to discuss/present the topic/updates and gather input and supporters. We believe all the issues that were brought up have been sufficiently discussed and addressed in the draft, and we have not seen objections to the proposal, so it is appropriate to adopt this informational draft as a WG document. The adoption process, and work on the document by the WG after adoption will improve it further.

Hopefully, people are coming back from their vacations and will speak up their thoughts.

Thanks.
Jeffrey

Dear DMM Team:

During the IETF-117, we have presented and discussed our IETF draft: ‘Mobile User Plane Evolution’ (draft-zzhang-dmm-mup-evolution: https://datatracker.ietf.org/doc/draft-zzhang-dmm-mup-evolution/<https://urldefense.com/v3/__https:/datatracker.ietf.org/doc/draft-zzhang-dmm-mup-evolution/__;!!NEt6yMaO-gk!EK_rpxFyiyc83DZJzh4RPbd0YkJPuxR3_9ox2_KhDo9ABaUZGfBEa9juMF9q91PN0_pEPjdFxcZCKY8JwZvouq1rNQ$> ). In the presentation, we explained the fundamental ideas of the I.D., along with our objectives. As we have stated, this was the 6th iteration of the I.D. Including this time (of IETF-117), different versions of the drafts have been presented & discussed thru the IETF-114, -115, -116 & -117.

At the moment, we believe we have covered sufficiently various aspects of the MUP-evolution, i.e., the potential integration of gNB & UPF with targeting at B5G & 6G. These are comprised of both IP-domain requirements & wireless technologies. Further, as of now,

  *   The 3GPP 4G LIPA work, i.e., the Local IP Access, bodes well for our (B5G, 6G) ‘ANUP-like’ proposal.
  *   The 3GPP Rel-19 planning (5G) is on-going and some potential work (of the I.D.) could be possibly brought it to 3GPP for further study (Rel-19); and
  *   The 3GPP Rel-20 (6G roadmap) targets toward the beginning of Y-2025, which is a perfect timing for exploration and adoption of the ANUP-like work.

Given all the work that have been done so far, we have, during the IETF-117 DMM session, initiated a possible adoption-call of the I.D., in the ‘informational’ track. We have emphasized our I.D. just serves as input to 3GPP and we don’t intend to do 3GPP work in the IETF community. For a procedural question from an on-site attendee of the DMM session, the 3GPP-to-IETF liaison manager has shared his opinion and said there is no problem to bring the ‘normal document’ to 3GPP for discussion/reference.

At the end of the session, the DMM chair suggested we bring this draft to the email alias. So, we are here to officially initiate the adoption-call of our I.D.
Team, please share your opinions, comments, questions, etc. Thank you.

BR,

-Tianji
