|ONF Connect Talks||Lyndon|
Thorsten - Q. on technology-specific models for the operator - issue brought up earlier - need for model "landscape" using core model to consolidate technology-specific models, to support operator multi-technology network control - possible sources could be IETF (but concerns with need for proprietary extensions), OpenConfig (no core model), ONF (good core model but need more technology-specific extensions)
OpenConfig seen to have an advantage due to the broad support of different technology-specific models - how can we extend ONF work? Propose guidelines for making technology-specific amendments to the Core Model, a cookbook that can be used by other groups/operators. Could initially cause some redundant developments, but ONF could follow up by some type of validation that guidelines are fulfilled, listing on ONF website, then identify what models are being supported across multiple operators/vendors, track the acceptance in the industry - goal to accelerate extension of the core model across technologies. Concern that if we are not able to do this, CIM work will become irrelevant.
What is needed beyond what is in TR512.7 and other documents? Should the models be defined in associated SDOs first? With TAPI, have worked closely to ensure consistency. What other technologies are needed? Thorsten - technically easy to add, but industry does not know this - needs to be made known to others that you don't need to understand all of the core model. Reality is that ONF is not seen as the place to solve modeling problems, compared to OpenConfig which identifies dozens of models on their website, even if each model is very limited. ONF appears too academic and not a place for solutions at this time. TAPI is known as a solution, also microwave model, but lots of areas not addressed (e.g., synchronization). Note operators may have different requirements on their models also, some may want only very simple models, or different needs depending on the application.
Could maybe start with OpenConfig models, integrate them with core model? Further discussion needed, item for OIMT as well. Kam and Thorsten to coordinate, possibly next Thursday (11/22) OIMT-E.
