Re: DMM WG Adoption Poll (2) for "Mobile User Plane Evolution" - draft-zzhang-dmm-mup-evolution-06

Hi Katsuhiro,

Please note that this document does not conflict with draft-mhkk.

Regarding “Control plane convergence should indeed play a pivotal role”, I observe that draft-mhkk is still based on the separate N2/N4 signaling in case of 5G, even though the N4 is translated to BGP.

In fact, while the AN + UPF integration will benefit from integrated signaling in 6G, in 5G the integration can be done as an implementation choice w/o integrating N2/N4, and it can even use BGP signaling (that was defined for draft-mhkk) – as in https://datatracker.ietf.org/doc/draft-zzhang-dmm-anup5g-signaling/.

Thanks.
Jeffrey

Hello,

I concur with this observation, as a co-author of draft-mhkk-dmm-srv6mup-architecture-05.
Control plane convergence should indeed play a pivotal role in realizing the original DMM concept,
as the control plane information serves as the foundation for route advertisements from (R)AN.
The genuine potential of ANUP can be fully realized when both user and control plane convergence are achieved.

Is there anyone willing to take the lead in driving control plane convergence for (R)AN within the IETF?

Best Regards,
Katsuhiro Horiba
