Re: [Ibnemo] [Nfvrg] 答复: 答复: Defining a Common Model for intent

["Natale, Bob" <[e-mail]>]

Major +1 from me Diego’s statement of the need … absolutely on the mark, in my judgment.

Two things I have found confusing in the threads on this topic:

- Use of “role” (and I think Diego may be questioning this too) … I think I understand the usage, but that term carries a certain specificity that is too rigid in the context of understanding the levels of translation usually modeled into policy-based management solutions … “views” or “perspectives” or something like that is more common.

- The targeting of “user” intent in this discussion … other than where “user” is proxy for “operator” or “provider” or something like that (and I think Bert might have touched on that too), I don’t think we should focus on user intents yet. I would agree that user intents will ultimately be addressed via successful intent-based policy management solutions but that’s too aggressive for where we are now … better to assume that user intents come into the service provider business model at the top and are mediated by that business model (e.g., via service offerings, SLAs, etc.) and represented in the intents that the service provider/network operator use to control network behavior on behalf the their users.

Avanti,

Hi,

Let me try to bring a new view on this (hence no quotation of previous exchanges) in the hope it helps to get to a common understanding.

Those of you who know me have probably heard me saying that to complete the promise of SDN we need something like a "network SQL": a declarative language based on a formal network model that would allow both defining network properties and manipulating network behavior, and, what is of capital importance in my view, support the seamless integration of these definitions and manipulations within general-purpose applications. This is my hope for intent-based networking, and that is my understanding of an intent expression.

An intent model would precisely define this formal network model on which to base the declarative language. Different models would support different views (or roles?) and therefore translate into different declarative languages, the same way we have several mechanisms to manipulate data that are not necessarily SQL.

Be goode,
