Dear Dave,

I got what you are saying.

>The sorts of features we are seeing in the larger 3GPP picture AFAIK are more recent additions for URLLC, CIoT etc.
>So picking and choosing based on convenience is not an option; the problem space is not a matter of choosing what to support,
>but in replicating the functionality exists and having similar extensibility.

In this particular case, I am afraid we can even take that kind of undertaking to create a complete "Stunt Double" as you put it.  I also believe this is not under the purview of IETF and inevitably we intervene with their control plane procedures to create this kind of framework.

I still believe we ought to develop value addition functionalities in the transport network layer, applicable to these deployments which brings a better E2E service. At the end of the day neither a packet traversing the network doesn't know which SDO owns this nor the end user consuming the service.

DA> I’d consider the “stunt double” capability in the user plane to be table stakes, the “value add” beyond that point is the “justify your existence” moment 😊


This is a generic comment and I am not implying to any particular work being done here.


BR!
