Hello,

Though this draft is mostly agreeable, drastic improvement also requires
the control plane work.
In fact, RAN Core convergence has already been discussed.
e.g.
https://ieeexplore.ieee.org/document/10073488
https://ieeexplore.ieee.org/document/10001281

ANUP solely addresses user plane convergence and tries to liaise with 3GPP,
but I'm afraid this is a half-baked attempt.

The MUP[*] assumes no change to 5GC, and I think IETF DMM should focus on
this at least for the time being.

Architecture:
https://www.ietf.org/archive/id/draft-mhkk-dmm-srv6mup-architecture-05.html
Motivation:
https://www.ietf.org/archive/id/draft-kohno-dmm-srv6mob-arch-07.html

Cheers,
Miya
