Re: Energy saving as an IETF goal

[Alvaro Retana <[e-mail]>]

I also think this could be an interesting topic for the IETF.

A few years ago we wrote a "Framework and Requirements for Energy Aware
Control Planes” [1].  There wasn’t a lot of interest at the time and we
intended to publish it somehow, but got busy on other things…

Along these lines, roughly a decade ago I filed a patent for selective
routing to data centers for purposes of power control and environmental
impact [1].  While I've left Juniper since, if there were interest, they
may be willing to assign the IPR to IETF if asked nicely.

That said, this patent somewhat missed the claim.  What's really needed is
power-based routing in general (not just to data centers), whereby how
green the power is matters.  Of course, getting routers to accurately
testify the greeness of their power source could be difficult...

I think it is an interesting topic and very much on topic for us to think
about. And a topic where potential savings could be significant. IT is a
huge energy consumer (as well as a producer of short-lived gadgets). IT
also has the potential to help optimise many non-IT processes, and
therefore directly reduce energy consumption and waste.

But of course this is also complex topic and not one where only IETF or
only standards help. And a topic where continuous improvements in compute
and comms are often offset by more high res videos and ever growing
software packages (as well as auto-play and zillions of adverts, placed on
my screen after way too much ML analysis).

I’d be eager to work on this, assuming we can come up with proposals that
can have an impact.
