Re: Power aware networks : Comments requested from routing community

There are two different aspects to power-aware routing that I think are of
interest.
The first is developing a framework and method for evaluating different
possible solutions.
We had a discussion of draft-retana-rtgwg-eacp-00 in RTGWG in July 2012.

The second is examining and considering control plane and routing solutions
in that context.
That seems to me to be more likely something for the IRTF, rather than the
IETF.

The former, however, is where I think that the IETF's operational knowledge
and experience
could be useful in framing what would be a useful solution.

Would it be possible to discuss this work that Balaji is presenting in that
context?
In other words, if the goal of the solution is X,Y, and Z, then this
mechanism seems useful/
not useful, has stability concerns, etc.

And then there are the questions about assumptions and goals...  All of
this is great to
discuss in RTGWG - there's been significant interest, but what is mature
enough for the
IETF vs. the IRTF and whether there are sufficient people to work in the
area is not clear.
