Hi Marisol, all,

Thank you for sharing this document.

FWIW, you may find some comments at:

  *   Pdf: https://github.com/boucadair/IETF-Drafts-Reviews/blob/master/draft-opsawg-poweff-00-rev%20Med.pdf
  *   Doc: https://github.com/boucadair/IETF-Drafts-Reviews/raw/master/draft-opsawg-poweff-00-rev%20Med.doc

I was expecting to see at least some references or reuse of some of the aspects already covered in documents such as rfc7460. I was also surprised by some deviations form the interface module without explaining the rationale.

Overall, the rationale for the modules structure and how they can be used to achieve the goals set in the first sections of the document are missing. Also, the document cites the inventory model but I was not sure whether you are referring to the IVY ongoing work.

This is a -00, so please don't be surprised by the 69 comments in the review.

Cheers,
Med

Dear OPSA WG,

Earlier this week, we posted a new draft that introduces a data model for power and energy related metrics :
https://datatracker.ietf.org/doc/draft-opsawg-poweff/
The focus is mainly on runtime information provided by power sensors, but also an extension to other related metrics and given attributes that will complement the representation of the energy consumed by the network device, implemented in hardware or software, as well as by specific network components.
This is a first-version approach where we see still challenges based on implementation.
Note: Some of those challenges are covered on Jan`s draft: draft-lindblad-tlm-philatelist<https://datatracker.ietf.org/doc/draft-lindblad-tlm-philatelist/>

Along with POWEFF draft, we've also updated the version of the Sustainability Insights draft:
https://datatracker.ietf.org/doc/draft-almprs-sustainability-insights/
where we introduced an updated architecture reference diagram, that provides a more structured view of the functional blocks that might be part of where those attributes and metrics might be produced, processed, visualized, etc. We also have reviewed and added Use Cases that such framework could drive.

We greatly appreciate your thoughts and comments.

Many thanks,
Marisol Palmero

Subject: New Version Notification for draft-opsawg-poweff-00.txt
A new version of Internet-Draft draft-opsawg-poweff-00.txt has been
successfully submitted by Marisol Palmero and posted to the
IETF repository.

Name:     draft-opsawg-poweff
Revision: 00
Title:    Power and Energy Efficiency
Date:     2023-10-20
Group:    Individual Submission
Pages:    37
URL:      https://www.ietf.org/archive/id/draft-opsawg-poweff-00.txt

Abstract:

   This document motivates and specifies a data model to report power
   and energy efficiency of an asset.  As highlighted during the IAB
   workshop on environmental impacts
   (https://datatracker.ietf.org/doc/html/draft-iab-ws-environmental-
   impacts-report-00), visibility is a very important first step
   (paraphrasing Peter Drucker's mantra of "You cannot improve what you
   don't measure").  During the workshop the need for standardized
   metrics was established, to avoid proprietary, double counting and
   even contradictory metrics across vendors.

   This Power and Energy Efficiency Telemetry Specification (POWEFF) is
   required to promote consistency across vendors and consumers, based
   on: 1.  The definition of datasets and attributes defining a common
   data model utilized by the standard calculation to yield power and
   energy efficiency value for any asset or network element.  2.  The
   standard calculations utilizing the specified datasets and attributes
   which will yield energy consumption and energy efficiency value for
   any asset or network element.

   The model provides information and data requirements for calculating
   the Power and Energy Efficiency for specific assets.  Assets can
   include hardware (physical or virtual), software, applications, or
   services.
