Modeling the Power Consumption and Energy Efficiency of Telecommunications Networks

This book introduces the technical foundations and tools for estimating the power consumption of internet networks and services, including a detailed description of how these models are constructed and applied. Modeling the Power Consumption and Energy Efficiency of Telecommunications Networks can be used to gain insight into the construction of mathematical models that provide realistic estimates of the power consumption of internet networks and services. This knowledge enables forecasting the energy footprint of future networks and services to integrate sustainability and environmental considerations into network planning and design.

FEATURES

• Provides the motivation for developing mathematical models for telecommunications network and service power consumption and energy efficiency modeling
• Presents factors impacting overall network and service power consumption
• Discusses the types of network equipment and their power consumption profiles
• Reviews the basics of power modeling, including network segmentation, traffic forecasting, top-down and bottom-up models, wired and wireless networks, data centers and servers
• Explores the application of energy efficiency metrics for equipment, networks, and services

This book is aimed at students and technologists as well as technology managers and policy makers. This book will be of value to any organization that wishes to estimate the energy footprint of the use of information and communications technologies. This book can also be integrated into a course on the sustainability of information and communications technologies.

Kerry Hinton

Kerry Hinton received an Honours Bachelor of Engineering in 1978, an Honours Bachelor of Science in 1980 and Master of Science Degree in Mathematical Sciences in 1982, all from the University of Adelaide. He was awarded a Ph.D. in Theoretical Physics from the University of Newcastle Upon Tyne, U.K., and the Diploma in Industrial Relations from the Newcastle Upon Tyne Polytechnic, U.K., in 1984.

In 1984 Dr. Hinton joined Telstra Research Laboratories (TRL), Victoria, Australia, where he worked on analytical and numerical modelling of optical systems and components. His work focused optical communications devices and architectures, physical layer issues for Automatically Switched Optical Networks (ASONs) and monitoring in all-optical networks.

From 1998 until 2010 Dr. Hinton was a sessional lecture for the Master in Telecommunications Engineering course at the University of Melbourne.

In 2006, Dr. Hinton commenced as a Senior Research Fellow in the CUBIN, at the University of Melbourne, Australia. In 2011 Dr. Hinton joined CEET as a Principal Research Fellow researching the energy efficiency of the Internet, communications technologies and networks.

Robert Ayre

Robert Ayre was awarded the degree of Bachelor of Science (with Distinction) from George Washington University in 1967, and the degrees of Bachelor of Engineering (with Honours) and Master of Engineering Science from Monash University in 1970 and 1972 respectively

In 1972 Mr. Ayre joined (what was to become) Telstra Research Laboratories (TRL). At TRL, he worked principally on optical transmission systems and networks, beginning with the earliest metropolitan multimode fibre systems through to long-haul optically amplified WDM systems. He was involved with Telstra's Engineering teams on optical network planning and in the first deployments of each of the new generations of optical transmission technologies. He also represented Telstra in the International Telecommunications Union Study Group XV on standards for optical transmission systems, and the International Electrotechnical Commission in developing standards for Laser Safety in Optical Communications Systems. Over time, he became responsible for a number of TRL's infrastructure development teams, covering Access networks, Core Transmission Networks, Data Networks, and Internet Services.

Following the closure of TRL, in 2007 he joined the Centre for Ultra Broadband Networks, (CUBIN) which later became the Centre for Energy Efficient Telecommunications, (CEET), at the University of Melbourne as a Senior Research Fellow.

Jeff Cheong

Jeff Cheong was awarded the degrees of Bachelor of Engineering (Honours) and Ph.D. from Monash University in 1976 and 1983 respectively. He then joined the Telstra Research Laboratories (TRL) in 1983.

During his career with TRL (1983 - 2006), Dr. Cheong led TRL in the development of control and signalling systems to facilitate the introduction advanced Intelligent Network (IN) PSTN services, service assurance systems for the rollout of VoIP and performance and monitoring tools for Telstra online services. He was also involved in the standardization of ITU-T Intelligent Network Capability Set 1 standards and the application of these standards for services rollout.

Dr Cheong previously held appointments with the University as Senior Research Fellow in CEET and the Institute for a Broadband-Enabled Society (IBES) (2013- 2014). In IBES he developed models for costings of fibre and civil infrastructures to support a National Broadband Network based on FTTP and for also fixed wireless technology. His research in CEET involved the modelling of energy efficiency of 3GPP LTE networks, the development of the GreenTouch Consortium's Mobile Communications WG Architecture, and development of models for quantifying energy savings of distributed vs. centralised mobile network architectures.

His current research includes development of analytical models for quantifying the performance of broadband access networks and the dimensioning of these networks.
