Satoru:



Your slide 6 shows one implementation (other operators may have other implementations).

Below is the Figure from CT4 TR 29.891. Can you show how your slide 7 impacts this

end-to-end protocol stack and which interfaces are impacted?



[cid:image002.png@01D39F22.C6C2DC80]





Your slides 9 - 13 show interactions between UPFs and SMF. There are 2 kinds of UPFs:

Anchor type UPF and service function type UPF. What are the functionalities of these?

What are the changes in SMF functionalities to support SRv6? Is the interface between

SMF and UPFs based on N4/Sx (PFCP in TS 29.244)?

Also you show IPv6/SRv6 nodes in those slides. Are the UPFs 'overlaid' on IPv6/SRv6 nodes?

Are these UPFs VNFs? Or are UPFs implemented on IPv6/SRv6 nodes?



It would be beneficial if you can provide clarifications and add a section to your draft.

Hello Kalyani,

Hope you find it in a tdoc from the following link:
