Architecture: Problem Description

Monitoring Power and Energy, based on existing data models (IEC 61850, IEC 62053-22, ANSI C12.20, …)

The target devices include: Router & switches Attached devices such as Power over Ethernet (PoE) devices But not limited to PoE devices. Example: PC Intelligent meters Proxy for building energy management Home energy gateway Etc…

Based on the requirement draft-quittek-power-monitoring-requirements-01

Currently some overlap with draft-claise-energy-monitoring-mib-04

Existing Implementation

Architecture: Example: Router, PoE, and non PoE device

5

Architecture: Example: BMS

IP

6

Architecture: Example: Smart PDU

7

Architecture: Overview of Scenarios

Use Case Scenarios

Scenario 1: Switch with PoE endpointsScenario 2: Switch with PoE endpoints + device(s)Scenario 3: A switch with Wireless Access PointsScenario 4: Network connected facilities gatewayScenario 5: Data Center NetworkScenario 6: Power Consumption of UPSScenario 7: Power Consumption of Battery-based

Architecture: Overview of New Concepts

Monitoring Power Monitor Information Power Monitor Meter Domain Power Monitor Parent and Child Power Monitor Levels Power Monitor Context

TBD Discovery Authentication Entitlement

Basically a new architecture for OPS We should lay down a good foundation for future

work in the energy area

Architecture: Concept of Parent/Child

The parent/Child = the parent reporting the power for the end point (child) And actually the parent controlling the child power states (not in scope) For example, Wake-on-Lan

Scaling issue if the NMS would control each child Building Management System requires a proxy

pmIndex 1, port, metered power

pmIndex 2, phone, negotiated power, parent = switch

pmIndex 3, PC, reported power, parent = switch

Abstract

This memo discusses requirements for energy management, particularly for monitoring consumption and controlling power states of devices.

This memo further shows that existing IETF standards are not sufficient for energy management and that energy management requires architectural considerations that are different from common other management functions.

Created from Requirements document

In Process of merging with claise monitoring MIB Contain the optional battery module

Abstract This memo defines a portion of the Management Information Base

(MIB) for use with network management protocols in the Internet community. In particular, it describes extensions to the Entity MIB to provide information about the energy consumption, the power states and battery status of managed devices and their components.

Via an agent

Known via LLDP-MED

Can we assume that the ENTITY-MIB is supported on all monitored devices?

No, so can’t use the entPhysicalIndex as THE index in the table New index: pmIndex, for each power monitor

18

Monitoring MIB: What’s new in version 3 & 4

Explained all the concepts More use cases Link with the LLDP-MED MIB User defined Power Levels Power Quality Better alignment with the IEC data model

More reviews from partners

Note: this is a very very quick summary of a 75 pages draft

draft-norwin-energy-consider-00

Recently Submitted

Lists and defines areas and concepts to be considered with energy management

Summary

Multiple drafts evolving together Requirements MIB Architecture

A series of new concepts for the architecture We should lay down a good foundation for future work in the

energy area
