Re: [Teas] WG adoption poll: draft-contreras-teas-slice-nbi-06

Luis,

I hear you but what you explained is matching exactly the definition of support documents (as per the IESG statement).

For a procedural standpoint: please note that the IESG will raise the question anyway about the value of publishing such a document. So, having formally discussed this within the WG is a generally a good argument to resolve DISCUSSes and avoid as much ABSTAINs.

So, let’s be pragmatic here and proceed in two steps: adopt with the commitment to reassess the archival value of the draft in due time. The WG may then decide to abandon or purpose the publication.

Thank you.

Cheer,
Med

Hi Adrian, Med, all,

Let me share my view in this specific point. I see the value on progressing this document separately as well as advancing it as potential RFC for several reasons. Certainly it intends to identify parameters to be taken into account by the NBI YANG model for making such NBI comprehensive (and not limited to few situations), but it can also provide referential material for other documents such as the framework document (some use cases are listed at the beginning without further elaboration), solutions documents (e.g., draft-srld-teas-5g-slicing, draft-barguil-teas-network-slices-instantiation, …), as well as others.

Furthermore, it also provides a way of understanding how different use cases can make use of IETF Network Slices for solving the connectivity part, with adaptation of parameters and procedures not defined in IETF to those defined in IETF, then providing exemplary guidance on how to consume IETF Network Slices. Finally, it can help other WGs in IETF to provide overall context on the usage of IETF Network Slices.

A document like this was one of the objectives of the old Design Team, and the discussion on the mailing list just before IETF 113 made evident the need of having a reference in this respect.

Best regards

Luis

That’s a reasonable argument, Med. Thanks.

Might be nice to include a statement of intent in the Abstract/Introduction along the lines of “This document is intended to provide motivation and support for work on YANG models for the IETF Network Slice Service interface. As such, it might not be necessary to advance it to publication as an RFC.”

Cheers,
Adrian

Hi Adrian, all,

(focusing on this specific comment below)

As you known, adopting does not mean that the document will make it to the RFC stage. IMO, this document is a good ** support document **. As such, it falls under https://www.ietf.org/about/groups/iesg/statements/support-documents/ and the WG may decide to let it expire when it serves its purposes or not.

The merit I see in formally adopting is to have a WG reference to assess the slice service model against a set of cases and capture consensus about any missing attributes that need to be reflected in the service model itself.

Cheers,
Med

Hi,

(Not late with this review!)

I only have one question about supporting the adoption of this document
and that is to wonder whether the work is overtaken by events. We
already have work progressing developing and specifying the IETF Network
Slice Service Interface YANG model in draft-ietf-teas-ietf-network-
slice-nbi-yang. That YANG model is surely based on discussions that
arise from this work, and I am not doubting the value of those
discussions. But I don't quite understand why we need to pursue this I-D
towards an RFC when it's principal purpose is surely to shape the
content of the YANG model. Have I missed the purpose of this draft?
