                      Energy Management Framework

Abstract

   This document defines a framework for Energy Management (EMAN) for
   devices and device components within, or connected to, communication
   networks.  The framework presents a physical reference model and
   information model.  The information model consists of an Energy
   Management Domain as a set of Energy Objects.  Each Energy Object can
   be attributed with identity, classification, and context.  Energy
   Objects can be monitored and controlled with respect to power, Power
   State, energy, demand, Power Attributes, and battery.  Additionally,
   the framework models relationships and capabilities between Energy
   Objects.
