                   Requirements for Energy Management
                    draft-ietf-eman-requirements-06

Abstract

   This document defines requirements for standards specifications for
   energy management.  The requirements defined in this document concern
   monitoring functions as well as control functions.  In detail, the
   focus of the requirements is on the following features:
   identification of powered entities, monitoring of their power state,
   power inlets, power outlets, actual power, power properties, consumed
   energy, and contained batteries.  Further requirements are included
   to enable control of powered entities' power supply and power state.
   This document does not specify the features that must be implemented
   by compliant implementations but rather features that must be
   supported by standards for energy management.

Status of this Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF).  Note that other groups may also distribute
