Hi Reza,

I agree on the fact that the most interesting use case is cloud RAN but I don't really like the way it's illustrated (I know it's difficult).
>From the picture it seems that INS3 and INS4 are part of the radio slice, while they are not. The same applies to the RAN box. DU, and mostly CU, might be deployed even further into the network (the CU could easily be together with the Core), that would make the RAN extend all over till the Core.
Moreover the FN and MN from our point of view are like any other TN  (and if the core moves to the right all the TNs become MNs ?

My suggestion is to remove RS and CS from the picture and explain them verbally and call on the transport network TNs.

Subject: [Teas] 5G use-case for Framework draft

Hi Adrian,

As per discussion during the TEAS presentation at IETF 113, attached please find the application of IETF network slicing on 5G use-case.
Please note that I have included the applicability of IETF network slices in three different deployments for completeness. If you want to pick one of these use-cases and include them in Framework document, my suggestion is to include the very last one (I.e., C-RAN) use-case. Please reach out if you need more information on these use-cases.

Reza
