Hi all,

Due to a presentation order change and time shortage, we were not able 
to present the 5g-uplane-analysis draft yesterday. The presentation 
materials are uploaded below, so if you are interested in them, please 
check them out.
https://datatracker.ietf.org/meeting/109/materials/slides-109-dmm-user-plane-protocol-and-architectural-analysis-on-3gpp-5g-system-01

Also, as you can see in the email from Shunsuke, we're looking for 
feedback on the future direction of this draft, so please let us know if 
you have any ideas.

Regards,
Takuya
