Re: [v6ops] Interest in energy consumption

Fred,

Managing power may involve Management Information Base (MIB) which may 
be expressed as a YANG model.  We have just submitted an Internet Draft 
"YANG model for battery MIB" in the closed eman WG:
https://tools.ietf.org/html/draft-petrescu-battery-mib-yang-00

In this model IPv6 does not appear explicitely, but there is a link:
YANG modelled MIBs may be queried by SDN tools which in turn may run on 
IPv6.  Our home-brewed SDN tool managing mobile platforms such as 
smartphones runs fully on IPv6: both data and control planes.  We 
consider JSON but also YANG.
