TAOS is involved in standardization activities and actively participated in discussions and meetings. Currently, TAOS is setting up 9 new IEEE standards in the Green ICT area. These 9 standards were approved in September and October 2016 by the IEEE Communications Society Standards Development Board. They were also approved by the IEEE Standards Association (IEEE-SA) in December 2016.

Three working groups have been formed, all under the IEEE Communications Society standards Development Board:

  1. the IEEE Energy Efficient ICT (EEICT) working group, chaired by Jaafar Elmirghani, a previous TAOS Chair;
  2. the Green ICT Emissions working group;
  3. the Energy Efficient Communications Hardware (EECH) working group;

The final draft of the standards is due September 2018 and the final sponsor ballot is due for completion by September 2019.

IEEE Energy Efficient ICT standards

  1. IEEE P1925.1 is a standard for energy-efficient dynamic line rate transmission systems. This standard specifies an energy-efficient rate-adaptive transmission system that can be used to deploy mixed line rates. It introduces the architecture and mechanisms needed to enable the use of an optimal combination of line rates to accommodate traffic while reducing power consumption.
  2. IEEE P1926.1 is a standard for a functional architecture of distributed energy efficient big data processing. It specifies a functional architecture that supports the energy-efficient transmission and processing of large volumes of data, starting at processing nodes close to the data source, with significant processing resources provided at centralized data centre.
  3. IEEE P1927.1 is a standard for services provided by the energy-efficient orchestration and management of virtualized distributed data centers interconnected by a virtualized network. This standard specifies an architecture for a service composed of distributed data centers interconnected by a network. It specifies the interfaces and the dynamic orchestration and management mechanisms for energy-efficient allocation of resources from data centers and network.
  4. IEEE P1928.1 is a standard for a mechanism for energy-efficient virtual machine placement. This standard specifies an algorithm for energy-efficient virtual machine placement strategies considering network and computational power consumption. It also considers the geographic distribution of user demand.
  5. IEEE P1929.1 is an architectural framework for energy-efficient content distribution which specifies a framework for designing energy-efficient content distribution services, such as migration, placement, and replication, over networks.

Green ICT Emissions standards

  1. IEEE P1922.1 – Standard for a method for calculating anticipated emissions caused by virtual machine migration and placement. https://standards.ieee.org/develop/project/1922.1.html
  2. IEEE P1922.2 – Standard for a method to calculate near real-time emissions of information and communication technology infrastructure. https://standards.ieee.org/develop/project/1922.2.html

Energy Efficient Communications Hardware

  1. IEEE P1923.1 – Standard for computation of energy efficiency upper bound for apparatus processing communication signal waveforms.
  2. IEEE P1924.1 – Recommended practice for developing energy efficient power-proportional digital architectures. https://standards.ieee.org/develop/project/1924.1.html


The TAOS Liaison to the IEEE Standards Association is Prof. Jaafar Elmirghani, who chairs the IEEE-SA Energy Efficient ICT working group. He also chairs the newly formed IEEE Communications Society Green ICT Standards Committee, responsible for the sponsorship of all Green Standards, current and future, in the IEEE Communications Society.

The relationship with the IEEE-SA is very close and very successful, having led to the 5 EEICT standards named above which are directly prepared by TAOS members. The relationship has also led to 4 additional standards on Green ICT Emissions and EECH (a total of 9 standards), which were also prepared by members of TAOS working with a broader industrial and academic base within and outside TAOS.
