Hi Shunsuke, “As far as I read other comments on the terms, most of people seem to focuses on use cases where IETF network slices are provided as a type of network services (i.g., case1), and I’d like to confirm if case2 is also in our scope and “customer” can cover both cases. (I personally want to avoid using different terms depending on assumed use cases).” I agree with you that both should be in scope. I don’t see slicing different compared to other network services. The “customer” can be used for both internal and external cases. Cheers, Med De : Shunsuke Homma [mailto:shunsuke.homma.ietf@gmail.com] Envoyé : vendredi 7 mai 2021 04:53 À : Oscar González de Dios <oscar.gonzalezdedios@telefonica.com> Cc : Loa Andersson <loa@pi.nu>; adrian@olddog.co.uk; BOUCADAIR Mohamed TGI/OLN <mohamed.boucadair@orange.com>; teas@ietf.org Objet : Re: [Teas] Moving forward with draft-ietf-teas-ietf-network-slices Hi, Firstly, I also follow the WG consensus, and I’m ok to use “customer” if WG prefers it. I assume there are mainly two types of use cases on (IETF) network slices: 1. Providing slices to externals(customers) as a network service 2. Operating some internal network resources with the same slice system with case1 As far as I read other comments on the terms, most of people seem to focuses on use cases where IETF network slices are provided as a type of network services (i.g., case1), and I’d like to confirm if case2 is also in our scope and “customer” can cover both cases. (I personally want to avoid using different terms depending on assumed use cases). Btw, I agree with that slice management would be important, and we’ll need to clarify what “customers” and “providers” can do on slice managements. In my memory, the NS-DT’s study was started with an assumption that resources should be abstracted from several reasons, such as usability, scalability, security, etc. In this assumption, in my understanding, who controls network resources will be always slice provider (i.e., the owner of NSC). In other words, customers never manage resources structuring a slice directly, and a customer will send a service request to a slice provider/NSC when he/she wants to create/change/delete a slice. (I think this is fit to operation models considered in other SDOs such as TMF.) What can be done via service request will depend on design of slice service, and the current definition part provides just minimal sets of selectable parameters as SLOs. More details are provided in NBI drafts.
