Hi Ron, all,

Sorry if I missed something.

While I see interesting to announce that a power group is power-save capable, I 
would also see interesting the possibility to advertise that a power-group is 
in fact in power-save mode. Announcing the capability could be useful for 
external elements to later interact with the node but advertising the current 
power-save mode can be also useful for standalone node decisions like 
energy-aware flex-algo for example.

About the unidirectional Sleeping BW, could you expand on the use case?.

Thanks,

Raúl Arco.

Abstract:

   This document introduces Power Groups.  A Power Group is a
   hierarchical abstraction of power consumed by hardware components.
   In IS-IS, interfaces can reference the Power Group to which they
   belong.  Therefore, Power Groups provide a method of organizing
   interfaces into groups by power characteristics.

   The TE path placement algorithm can use Power Group membership
   information to implement TE policy.  Power Group information is
   particularly useful when implementing TE policies that support power-
   savings and sustainability.
