Requirements for Energy Management
draft-ietf-eman-requirements-14
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. Monitoring
functions include identification of energy-managed devices and their
components, monitoring of their power states, power inlets, power
outlets, actual power (the instantaneous power, as opposed to the
demand, which is an averaged power), power attributes, received
energy, provided energy, and contained batteries. Control functions
serve for 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 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
working documents as Internet-Drafts. The list of current Internet-
Drafts is at http://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."
This Internet-Draft will expire on November 03, 2013.
