Hi Lou, chairs, Based on the feedback on the list, could we conclude that we go to B) or do you want to wait more ? We would like to close work on multiple YANG models, and today ops state are blocking ... would be good to close it asap. Best Regards, Stephane -----Original Message----- From: netmod [mailto:netmod-bounces@ietf.org] On Behalf Of Lou Berger Sent: Tuesday, June 07, 2016 16:20 To: netmod WG Cc: netmod-chairs@ietf.org Subject: [netmod] Opstate solutions discussions: update and request for WG input All, We want to provide an update based on the off line discussions related to OpState Solutions that we have been having and solicit input from the WG. All authors of current solution drafts [1,2,3] together with those who helped conduct the solutions analysis* were invited to the these discussions -- with the objective of coming up with a single consolidated proposal to bring to the WG. (I/Lou acted as facilitator as Kent and Juergen were and are involved with the technical details.) The discussions have yielded some results but, unfortunately, not a single consolidated proposal as hoped, but rather two alternate directions -- and clearly we need to choose one: 1) Adopt the conventions for representing state/config based on Section 6 of [1]. From a model definition perspective, these conventions impact every model and every model writer. 2) Model OpState using a revised logical datastore definition as introduced in [4] and also covered in [5]. There is also a variant of this that we believe doesn't significantly impact this choice. With this approach, model definitions need no explicit changes to support applied configuration. >From a technology/WG standpoint, we believe an approach that doesn't impact every model written (i.e., #2) is superior. The counterpoint to this is that the conventions based approach (i.e., #1) is available today and being followed in OpenConfig defined models. We would like to hear opinions on this from the WG before declaring one of the following as the WG direction: A) models that wish to support applied configuration MUST follow conventions based on [1] -- and the WG needs to formalize these conventions. or B) no explicit support is required for models to support applied configuration -- and that the WG needs to formalize an opstate solution based on the approach discussed in [4] and [5]. We intend to close on this choice before Berlin.
