Hi Med, thanks again for your extensive review. For the benefit of the list, I reproduced your high-level comments here and add some answers. The diff is here https://www.ietf.org/rfcdiff?url2=draft-ietf-opsawg-service-assurance-architecture-04 for all the details.
Title: MED: "A YANG-based Service Assurance Architecture" We want to keep the current title. I think that the document clarifies that we consider the service approach as an primitive intent-based approach, and the architecture can accommodate more explicit intent declarations. Abstract: About "network root cause" MED: I see some text in the intro and security sections. I'm afraid that including this claim in the abstract need to be backed with more discussion in the document. Removed "root cause" from the abstract and stated in the introduction how our approach can help with root cause. Introduction: About " an assurance graph, deduced from the service definition and from the network configuration" MED: It would be helpful to clarify if it only consumes network models (e.g., L2NM, L3NM) or the collection of the various device modules that are enabled in all network nodes. Clarified that our approach does not assume that the SAIN orchestrator knows the Service model. If it is known, then it can be interpreted, otherwise only device model can be exploited. Section 3.2: About: "Try to capture the intent of the service instance" MED: Why not providing the intent in the first place rather than inferring it from the configuration? Explictly providing the intent might mean modifying current service models or at least defining a mapping from them to the intent. Added in text that if service model is known to the SAIN orchestrator, then it can be used to provide intent. Section 3.8: About "Flexible Architecture" MED: I think you just meant the arch is a functional one, not an organic arch. Renamed the section "Functional Flexible Architecture" I am available for any further comments and addressing your comments on the companion -yang draft as well. Thanks again, Jean From: OPSAWG [mailto:opsawg-boun...@ietf.org] On Behalf Of mohamed.boucad...@orange.com Sent: Monday 20 June 2022 15:12 To: Tianran Zhou <zhoutianran=40huawei....@dmarc.ietf.org>; opsawg@ietf.org Subject: Re: [OPSAWG] WGLC for draft-ietf-opsawg-service-assurance-architecture-03 Hi all, Many thanks to the authors for the effort put into this document. I think that the document is better compared to the last time I reviewed it. However, I think that some changes are needed to better articulate the intended behavior and overall operation. I had to jump several times between the terminology section (and some key elements in the introduction) and the core text to digest the concept that are being discussed. The flow can be worked better. FWIW, some more detailed comments can be seen at: * pdf: https://raw.githubusercontent.com/boucadair/IETF-Drafts-Reviews/master/draft-ietf-opsawg-service-assurance-architecture-03-rev%20Med.pdf * doc: https://github.com/boucadair/IETF-Drafts-Reviews/raw/master/draft-ietf-opsawg-service-assurance-architecture-03-rev%20Med.doc Cheers, Med De : OPSAWG <opsawg-boun...@ietf.org<mailto:opsawg-boun...@ietf.org>> De la part de Tianran Zhou Envoyé : mercredi 8 juin 2022 12:00 À : opsawg@ietf.org<mailto:opsawg@ietf.org> Objet : [OPSAWG] WGLC for draft-ietf-opsawg-service-assurance-architecture-03 Hi WG, This mail we start a two weeks working group last call for draft-ietf-opsawg-service-assurance-architecture-03. https://datatracker.ietf.org/doc/draft-ietf-opsawg-service-assurance-architecture/ Please send over your comments before June 22.
