Hi, please add AERO to the list: https://datatracker.ietf.org/doc/draft-templin-aerolink/ AERO does IPv6 ND over tunnels, and supports mobility via dynamic neighbor cache updates the same as any IPv6 link. Use cases include (but are not limited to): - Enterprise mobile devices (cellphones, table

Thank you Fred. There is a reason for mobile architectures shifting towards CP-UP split architecture (Ref: DMM WG documents + 3GPP CUPS), and the stated goal of further simplification in the mobile user plane (Reference: 3GPP CT4 Study item and 3GPP Liaison statement to DMM). Now, it will be goo

Sri, Your summary is comprehensive as it includes DHCP & IKEv2 too though they didn't ask specifically. For IKEv2 I see similar stuff needed for Config Payloads (for most of the attribute types), but not sure how this would be used in FMC cases (non-3GPP access). -- Uma C. -Original Mess

Hello Sri, This is more about address coloring than the Liaison statement. The approach of coloring IPv4 and IPv6 addresses/prefixes with mobility properties. This is about standardizing IP address address/prefix ³types". Each ³type" has a certain behavior that the network is expected to provi

There were several issues raised. I don't think fragmentation actually came up as one of them, but that is good point. [Uma]: Yes. Intermediate nodes cannot fragment packets in IPv6. … - The proposal attempted to carve out an exception to RFC8200 for just SR and limited use to controlled domai
