[nmrg] Asking for feedback on a proposal for including compute and data awareness as part of a broad SDN architecture

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

Dear group,

Hope this mail finds all you well, and let wish all you a great 2022.

I prepared a draft for IETF112 that could not be presented at that time. The document, draft-contreras-nmrg-clas-evolution-00 (https://www.ietf.org/archive/id/draft-contreras-nmrg-clas-evolution-00.txt), augments a previous SDN architecture proposition (described in RFC8597, which was primarily adopted in the extinct SDNRG and then released as ISE document) by introducing two new aspects:

.- on one hand, the augmented architecture considers control, management and resource plane dimensions for compute capabilities, framed in a Compute Stratum which interoperates with the previously defined Service and Network (previously referred as Transport) Strata. The objective of this augmentation is to consider an integrated management of the more and more commonly deployed computing facilities in operational networks (cloud, edge, etc) which require a tighter integration with the network providing the connectivity of such environments.

.- on the other hand, the augmented architecture considers a new dimension related to the handling of data (e.g., telemetry, monitoring, etc) that can feed Artificial    Intelligence (AI) and Machine Learning (ML) capabilities assisting on closed loop automation processes, by defining a new Learning Plane associated to the other three aforementioned planes. The objective of this augmentation is to complement the control and management procedures with this new concern related to data that can act at different strata (and timescales), but interacting and interchanging among strata.

The intended final research objective and value proposition of the draft is the formalization of a comprehensive architecture supporting recent advances on overall management procedures, that could permit a further investigation on forms (e.g. APIs) to allow the interaction among strata. While I think this fits on the purpose of NMRG, I would like to collect feedback from the group about if this approach makes sense for the group and if there is interest to develop these ideas further.

Thanks in advance

Best regards

Luis
