Re: [OPSAWG] side meeting #119: Power Metrics: concrete usage example

[Carlos Pignataro <[e-mail]>]

Hi, Rob,

Thanks for the comprehensive email, and for your desire to support the industry towards improved energy efficiency! 

My first reaction is that this direction seems counter to and in conflict with the conclusion and decisions from the IAB Program eimpact “interim” from just a month before:
See Chair Slides <https://datatracker.ietf.org/meeting/interim-2024-eimpact-02/materials/slides-interim-2024-eimpact-02-sessa-chair-slides-01>, that codified: "Metrics – Push through the WGs” (etc. etc.)
See Minutes <https://datatracker.ietf.org/meeting/interim-2024-eimpact-02/materials/minutes-interim-2024-eimpact-02-202402161500-00>, that captured: "Suresh agreed and mentioned that the reason for having the drafts here is that people to get higher level view since all working groups need to have a sustainability angle"

A second thought is that, while on the surface getting a couple of document with ‘green metrics’ is useful and might seem net-positive, knee-jerk reacting on tactics misaligned with strategy can further fragment the Eimpact work (which already can be characterized as ‘having a hard time finding itself’ with work from 2022 and no output).

There are clear risks like (1) believing that metrics/models are the ultimate goal of “eimpact/green’ work, while (as mentioned on eimpact) there’s no analysis of the most useful focus area, and (2) forgetting what Suresh wrote that many WGs need ‘green’, and this would separate work in a corner, as opposed to embedding and integrating it.

A third thought is that we had asked for a (broader and more e-impactful) WG a year ago, and that was shot down in favor of this IAB Program :-|

Fourth, ‘green-bof’ is very very broad, while I understood your desired scope to be narrow. This would eclipse eimpact as the shinny new ball, and would potentially confuse people on where to participate (outside the lucky ones that attended a side meeting)

Fifth, and Lastly — frankly I was debating with myself whether to mention this privately or not, but since you brought it up and opened the topic — another issue. Backdrop: BOF and WG-forming suggestions were sent to /dev/null favoring the IAB Program as the solution. What follows is a set of factual observations and no judgement or intentionality attached to them. But there’s (1) cisco proponents and cisco side-meeting organizer despite the eimpact interim, (2) with a Cisco-only I-D [1], (3) a Cisco AD meeting with (4) a Cisco IAB Member, in the (5) historically least attended meeting, and change direction 180 degrees… Again, no extrapolation or conclusion, but even from an appearance or optics perspectives.

Yes, I continue contributing in the industry and field to this topic, and I would cautious you consider a bigger picture to see what approach(es) actually help.

I hope and trust these are useful and clear, 

Best,

Carlos.

This seemed to somewhat culminate during the Power Metrics side meeting where it is clear that:

E.g., roughly, I currently think of this work scope as being: e.g., energy related terminology and definitions (that should try and leverage and reference existing definitions from existing published sources), reporting energy and sustainability at the device and network layer via operational YANG models, and to facilitate configuration or YANG RPCs to influence and optimise power usage on network devices.  Longer term energy efficiency and Green networking goals are intended to be out of scope for the proposed WG’s initial charter, and should continue to be discussed as part of the E-Impact IAB program.  The exact scope of the charter would be worked out between the interested parties in the coming weeks.

I appreciate that several of the proponents for this work are also from Cisco, but I have no vested interest other than trying to help the industry take small steps that may help improve energy efficiency in networks (e.g., reporting power usage, and as Tony suggests by selectively powering off ports or linecards) to try and help mitigate some of the impacts of the Internet on climate change.

If I can get this under the IETF github space, great, otherwise I can host a personal github.  I’m already checking with Mahesh on the feasibility of the github location being IETF hosted.

I cannot find "design team" or 'BOF" (WG forming or not?) in the minutes of eimpact meetings <https://datatracker.ietf.org/program/eimpact/meetings/>, maybe I missed it.
