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.

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 Status: https://datatracker.ietf.org/doc/draft-opsawg-poweff/ HTMLized: https://datatracker.ietf.org/doc/html/draft-opsawg-poweff 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. The IETF Secretariat
