Presenter: Carlos J. Bernardos
Time: 10 minutes
Draft Reference: https://www.ietf.org/id/draft-ietf-dmm-pmipv6-dlif.txt

[Carlos] Utilizes PMIP for DMM. Need reviews.

[Pablo] Small updates on this version.
[Chair: Sri] How much work remained?
[Pablo] Not so much.
[Chair: Dapen] OSS implementation?
[Pablo] There is. The use case draft submitted on last Sunday shows places
where it will be deployed. [Chair: Sri] Is there any feedback from 3GPP on the
I-D [Satoru] Not specifically on the I-D but there's feedback on analysys.
[Chunshan] There's new functions defined which CT4 hasn't dealt with. The I-D
need to take it into account.

5.
Topic Name: Distributed Mobility Anchoring
Time:  5 minutes
Presenter: Carlos J. Bernardos
Draft: https://www.ietf.org/id/draft-ietf-dmm-distributed-mobility-anchoring.txt

[Carlos] Now the I-D looks stable after the reviews by Marco. Other voluntieers?
[Chair: Dapen] Need to align with the solution drafts.

6.
Topic name: Status Update on reviews of draft-ietf-dmm-ondemand-mobility-14
Presenter: Danny Moses
Time: 5 minutes
Draft Reference: https://www.ietf.org/id/draft-ietf-dmm-ondemand-mobility.txt

[Danny] Short updates from feecback after WGLC.
[??] IP continuity is much suitable on issue#1 IP session concept.
[Brian] Need description to make sure people who doesn't have context to be
understand. [Danny] Next step is update the I-D.

7.
Topic Name: Mobility-aware Floating Anchor (MFA)
Presenter: Marco Liebsch
Time: 10 minutes
Draft Reference: https://tools.ietf.org/html/draft-gundavelli-dmm-mfa.txt

[Marco] Explain concept of correspoing edge. Feedback on
[Chair] Who read the I-D? a few. Need to keep discussion on ML.

8.
Topic Name:  Discussion on liaison from 3GPP CT4 group
Presenter:  Satoru Matsushima / Chairs
Time: 5 minutes
Liaison Reference: https://datatracker.ietf.org/liaison/1572/
                   https://datatracker.ietf.org/liaison/1586/ (To be revised)

[Satoru] Thank to a lot of effort on this in IETF side. As 3GPP requests any
info on UP protocol to figure out criteria and candidate protocols, the LS
contents looks appropriated. [Dave] It includes non-WG documents which are not
clear when it comes to LS contents. (will followup the discusion later)

9.
Topic Name: User Plane Protocol and Architectural Analysis on 3GPP 5G System
Presenter: Shunsuke Homma
Time: 15 minutes
Draft Reference: https://www.ietf.org/id/draft-hmm-dmm-5g-uplane-analysis.txt

[Shunsuke] Present summary of the outcome from the analysis and introduce
feedback from 3GPP CT4.
                Next step is update the I-D based on feeback. Intend to be a
                part of LS reply.
[Arashmid] That looks basic ground work.
[Dave] There is issue on this.
[Chair: Sri] How many people read the I-D? good number in the room. Keep
discussion on ML.

10.
Topic Name: Optimized Mobile User Plane Solutions for 5G
Presenter: Arashmid Akhavain
Time: 15 minutes
Draft Reference: 
https://www.ietf.org/id/draft-bogineni-dmm-optimized-mobile-user-plane.txt

[Hannu] Clarify service chaining on which interface?
[Arashmid] N9. it is funciton chaining in general. not specific on service
chaining on N6. [Alberto] Present LISP and ILA parts [Dino] Followup on LISP
which involves not only on N9, but also on N3 and N6.

[Dino/Arashimid] Need to describe the mapping system.
[Chair:Sri]
[Dino] Ask to the chair, how many candidates we bring to CT4, less or more?
[Georg] Study item is second priority so not to expect too much.on 3GPP. Need
