Hi WG, I think this work is very useful. I have some comments -
Minor - We need a reference or some discussion of what we mean by "intent" before we jump into SAIN in the Introduction. - The statement "Such approaches are mainly suited for greenfield deployments" about intent is not clear to me. Is the intent-based approach (or SAIN) limited to new deployments? Maybe it is worth expanding on or providing a reference. - It is not clear to me the various difference between the Expression graph, assurance graph, and computational graph. If the expression graph/computation is all about how the health score is to be calculated, why is that not in the YANG (which only talks of assurance graph)? Also, I don't understand the difference between subservice and service expressions! If the subservice has dependencies, does it become the same as the service expressions? The model YANG only has subservices BTW! - Does SAIN orchestrator has any say in what metric to collect and how it impacts the health score? I understand in most cases it is to be analyzed from the configuration but at the same time can that not be influenced by the orchestrator? - Some examples of how the health score might be calculated as an integer between 0-100 would be nice in the example provided esp for a case where it is something in middle like "60". Nits - Section 1, the closing parenthesis is missing -> (Section 3.3 of [RFC8969] - Expand on first use - L3VPN, dBM, - Add reference for kubernetes, Openconfig Thanks!
