From: Ciavaglia, Laurent (Nokia - FR/Paris-Saclay) <laurent.ciavaglia@nokia.com> Sent: Thursday, July 25, 2019 07:21 To: nmrg@irtf.org Cc: nmrg-chairs@irtf.org; Mohamed-Faten.Zhani@etsmtl.ca Subject: RE: NMRG Interim meeting aka IBN workshop - Friday July 26th - ETS Montreal Hello NMRG, For our workshop on Friday, I would like to share and stress one aspect I would like us to investigate and exercise. This is the aspect of intent examples. I would invite each of the participants to think and propose one or more examples of intents. We will then run through a set of questions and "tests" to see if/how far we can go with the proposed intent examples: are some "parts" missing, incomplete, too approximative? Are the functions we are thinking of in the architecture enough to transform the proposed intents to the required level of output (e.g. configurations), are we missing some functionality to achieve the process or some capabilities to make the functionality complete, etc Also, what are the commonalities and differences we could identify between the different intent examples proposed, how does it help on the work of intent classification, is it consistent or points to aspects we have overlooked? Who are the actors/roles involved e.g. expressing intent, validating intent, mapping/translating/rendering, etc. These examples could be linked to simple use cases or technologies to help us better grasp the exercise and help us validate the approach. I strongly believe this will help us to move forward in the several activities we are engaging on intent based networking: terminology, classification, architecture, validation scenarios, human-network interface… As starting point, after some search and thinking I could come up with the following proposal/basis, for discussion: Intents are composed of: a functional and an operational part. The functional part consist in the expression of the business goal, the expected outcome. The operation part captures the performance parameters such as network/compute/memory, time, space/topology ; security ; availability, etc. Units, metrics and value/value ranges may also be specified. I don't know if cost or cost vs. x,y,z ratio should be considered in the intent expression. We can also consider aspect of logic and operators, semantics… but we have to set some scope also first not to get lost in the complexity. I think getting towards such "structures" could help us defining guidelines how to write intents and systems to parse them without imposing a single format or language. I'm also deeply convinced that the intent "expression/refinement" process should edge towards continuous, iterative and interactive process rather than one shot intent expression. We can also try to characterize different categories of intent (and use the corresponding draft as a support): business intents: end-users and operators: both have business intents for the system under study but have/are in different businesses. Food for thoughts. Best regards, Laurent.
