Re: [Teas] WG Adoption Poll - draft-wd-teas-ietf-network-slice-nbi-yang-04

[LUIS MIGUEL CONTRERAS MURILLO <[e-mail]>]

Hi all,

Yes/Support.

In my opinion an IETF Network Slice has special characteristics which can require a different model to express them. For instance, SLEs as the ones described by now in draft-ietf-teas-ietf-network-slices (i.e., isolation, security, etc) could imply different mappings later on existing models (or maybe different kind of augmentations, if the capabilities do not exist already) when choosing a specific technology or architectural framework for slice realization.

An example of this could be the case of the VN as discussed in this thread. A slice requested with a Network Slice model with SLOs/SLEs as expected by slice customers could use e.g. the auto-creation capability at MDSC for later realization following ACTN architecture. Part of the SLEs could be maybe out of the VN model, but yet relevant for the slice realization. That is why an specific model could be needed.

Being said that, I would advocate for a consistent definition of draft-wd-teas-ietf-network-slice-nbi-yang and draft-liu-teas-transport-network-slice-yang since they represent two alternatives for slice request that could be expected to be found at the NBI of the Network Slice Controller (as described in draft-contreras-teas-slice-controller-models). In essence, align/integrate both models.

Best regards

Luis
