Hi,
FYI, we have just posted an update to the draft "Green Networking
Metrics", renamed draft-cs-opsawg-green-metrics to reflect the fact that
we consider OPSAWG to be the appropriate landing spot, per earlier
discussions after presentation of predecessor versions at previous
IETFs. The draft can be found here:
https://datatracker.ietf.org/doc/draft-cx-opsawg-green-metrics/
We have made a number of updates from the previous revision. These
include a new section 4.6 on related metrics defined elsewhere, notably
ETSI, and a new section 5 on controversies, discussing pitfalls and
caveats related to the use and interpretation of metrics in isolation
(taking into account a longer discussion thread on the e-impact mailing
list). The new draft also provides a better distinction between the
concepts of energy efficiency and carbon footprint and strengthens the
distinction between "primary" (directly measured) and "derived"
(computed on the basis of other metrics) metrics. Furthermore, it calls
out specific uses for certain metrics, in addition to various other
editorial updates and additional references.
Comments and suggestion are very welcome!
