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.
