Description of Working Group:


    Energy management is becoming an additional requirement for network
    management systems due to several factors including the rising and
    fluctuating energy costs, the increased awareness of the ecological
    impact of operating networks and devices, and the regulation of
    governments on energy consumption and production.

    The basic objective of energy management is operating communication
    networks and other equipments with a minimal amount of energy while
    still providing sufficient performance to meet service level objectives.
    A discussion of detailed requirements has already started in the OPSAWG,
    but further exploration in the EMAN WG is needed.
    Today, most networking and network-attached devices neither monitor nor
    allow control energy usage as they are mainly instrumented for functions
    such as fault, configuration, accounting, performance, and security
    management. These devices are not instrumented to be aware of energy
    consumption. There are very few means specified in IETF documents for
    energy management, which includes the areas of power monitoring, energy
    monitoring, and power state control.
    The OPSAWG started working on a MIB module for monitoring energy
    consumption and power states of energy-aware devices and found that more
    than just a MIB module was needed to manage energy in networks. Rather a
    new framework for energy management needs to be developed first.

    A particular difference between energy management and other management
    tasks is that in some cases energy consumption of a device is not
    measured at the device itself but reported by a different place. For
    example, at a Power over Ethernet (PoE) sourcing device or at a smart
    power strip, in which cases one device is effectively metering another
    remote device. This requires a clear definition of the relationship
    between the reporting devices and identification of remote devices for
    which monitoring information is provided. Similar considerations will
    apply to power state control of remote devices, for example, at a PoE
    sourcing device that switches on and off power at its ports. Another
    example scenario for energy management is a gateway to low resourced and
    lossy network devices in wireless a building network. Here the energy
    management system talks directly to the gateway but not necessarily to
    other devices in the building network.

    The WG will investigate existing standards such as those from the IEC,
    ANSI, DMTF and others, and reuse existing work as much as possible.
    The EMAN WG will work on the management of energy-aware devices, Covered
    by the following items:

    1. Requirements for energy management.
    The EMAN WG will develop a requirements document that will specify
    energy management properties that will allow networks and devices to
    become energy aware. In addition to energy awareness requirements, the
    need for control functions will be discussed. Specifically the need to
    monitor and control properties of devices that are remote to the
    reporting device should be discussed.

    2. Energy management framework.
    The EMAN WG will create a framework document that will describe
    extensions to current management framework, required for energy
    management. This includes: power and energy monitoring, power states,
    power state control, and potential power state transitions. The
    framework will focus on energy management for IP-based network equipment
    (routers, switches, PCs, IP cameras, phones and the like).
    Particularly, the relationships between reporting devices, remote
    devices, and monitoring probes (such as might be used in low-power and
    lossy networks) need to be elaborated. For the case of a device
    reporting on behalf of other devices and controlling those devices, the
    framework will address the issues of discovery and identification of
    remote devices.

    3. Energy-aware Networks and Devices MIB document The EMAN WG will
    develop a MIB module for monitoring energy-aware networks and devices.
    The module will address devices identification, context information, and
    potential relationship between reporting devices, remote devices, and
    monitoring probes.

    4. Power and Energy Monitoring MIB document The EMAN WG will develop a
    document defining managed objects for monitoring of power states and
    energy consumption/production. The monitoring of power states includes:
    retrieving power states, properties of power states, current power
    state, power state transitions, and power state statistics.
    The managed objects will provide means for reporting detailed properties
    of the actual energy rate (power) and of accumulated energy. Further, it
    will provide information on electrical power quality.

    5. Battery MIB document
    The EMAN WG will develop a document defining managed objects for battery
    monitoring, which will provide means for reporting detailed properties
    of the actual charge, age, and state of a battery and of battery
    statistics.

    6. Applicability statement
    The EMAN WG will develop an applicability statement, describing the
    variety of applications that can use the energy framework and associated
    MIB modules. Potential examples are building networks, home energy
    gateway, etc. Finally, the document will also discuss relationships of
    the framework to other architectures and frameworks (such as smartgrid).
    The applicability statement will explain the relationship between the
    work in this WG and the other existing standards such as those from the
    IEC, ANSI, DMTF, and others.
