[Lsr] Re: Adoption of draft-many-lsr-power-group

["Bonica, Ron" <[e-mail]>]

Marisol,

Look for these changes in the next version of draft-many-teas-power-steering and draft-many-lsr-power-groups.

I will probably have to contact you for coaching as I make the changes.

                                                              Ron

Subject: Re: [Lsr] Re: Adoption of draft-many-lsr-power-group

Hi Ron,

Under the Terminology section, there's a reference to draft-many-teas-power-steering. I checked that draft as well, and it doesn't reference the GREEN work either.


  *   Under Terminology, I'd suggest reviewing and referencing, possibly as an extension: draft-ietf-green-terminology.

I'd also review the GREEN use cases to make sure your use case(s) are covered under: draft-ietf-green-use-cases. And noted in the Introduction section, similar to your reference to  [I-D.many-teas-power-steering]


In the Operational section, I'd include the requirements for the GREEN framework, or any other framework that might support the use case, ... also including the device-specific details, that to my understanding should be align with the GREEN YANG data model:


  *   draft-ietf-green-framework —> see the relationship defined in Section 4.3: "A Functional Dependency Relationship is a relationship where one Energy Object requires another Energy Object to be in an operational state for its own correct functioning..."
  *   draft-ietf-green-power-and-energy-yang, where the relationship YANG data model has been included.

I'd reference these in Section 2 (Terminology) and/or Section 3, where relevant terms/dependencies are introduced.


Point 3 is covered with your suggestion. Please keep in mind that under the GREEN YANG data model


Just for you to note:
GREEN WG is considering accuracy and units for power in watts.

           leaf data-source-accuracy {
             type identityref {
               base data-source-accuracy;
             }
             default accuracy-like-parent;
             description
               "The accuracy of the power data source. Indicates whether
               the data source is a direct measurement, an estimate, or
               unavailable and also the accuracy level of the data source.
               By default, the accuracy is inherited from the parent energy
               object, facilitating hierarchical accuracy definitions
               without the need to specify accuracy at every level.
               This metadata is crucial for network management
               applications to assess the reliability and accuracy of the
               power data.";
           }

hth,
Marisol

The Power Group concept, Sleep Status, and PSP metric all directly relate to the energy management model defined in the GREEN framework (draft-ietf-green-framework) and GREEN YANG data model (draft-ietf-green-power-and-energy-yang). We request to address:  that Power Group membership and PSP values are intended to be consistent with what a device reports via the GREEN YANG model at the management plane.

> draft-many-lsr-power-group defines: "One Power Group is the child of another if any one of the child components depends upon any one of the parent components." This is precisely the Functional Enablement Relationship that GREEN WG has extended in its YANG model via the 'enabled-by' and 'enabling' identity pair. The draft should acknowledge this mapping explicitly, so that implementations can correlate IS-IS-advertised Power Group hierarchy with the management-plane relationship model in GREEN YANG without ambiguity.

> The PSP field (power saveable in milliwatts if a Power Group goes to sleep) is a prospective metric with no equivalent in the current GREEN YANG data model, which defines only actual and historical power values. Before the draft is adopted, it should be considered a prospective power metric leaf in a future revision of the YANG model. We request that the LSR document note that PSP values SHOULD be consistent with device-reported power data available via the GREEN YANG model where such data is available, to establish a baseline for interoperability between the IGP-distributed value and the management-plane value. It will be good to address this requirement from the LSR authors.
