Requirements for Energy Management
Abstract
This document defines requirements for standards specifications for
Energy Management. The requirements defined in this document are
concerned with monitoring functions as well as control functions.
Monitoring functions include identifying energy-managed devices and
their components, as well as monitoring their Power States, Power
Inlets, Power Outlets, actual power, Power Attributes, received
energy, provided energy, and contained batteries. Control functions
include such functions as controlling power supply and Power State of
energy-managed devices and their components.
This document does not specify the features that must be implemented
by compliant implementations but rather lists features that must be
supported by standards for Energy Management.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for informational purposes.
