Tutorials
The role of the tutorials is to provide a platform for a more intensive scientific exchange amongst researchers interested in a particular topic and as a meeting point for the community. Tutorials complement the depth-oriented technical sessions by providing participants with broad overviews of emerging fields. A tutorial can be scheduled for 1.5 or 3 hours.

Brief Bio
Kerry Hinton received a BE(Hons) in 1978 from the University of Adelaide and a Ph.D. in Theoretical Physics from the University of Newcastle Upon Tyne in 1984. In 1984 he joined the Telstra Research Laboratories working on modelling of optical systems and components. In 2006, He joined the University of Melbourne, in the Centre for Ultra-Broadband Information Networks. In 2011 he joined the Centre for Energy Efficient Telecommunications (CEET) researching the energy efficiency of the Internet. CEET is was industrial research centre funded by Alcatel-Lucent, the Victorian State Government and the University of Melbourne and is a world leader in researching energy efficiency in telecommunications. CEET is a founding member of the international GreenTouch consortium which has the goal of developing a technology road-map to improve the energy efficiency of the Internet by a factor of 1000. He was Director of the CEET from 2013 until its closure and his retirement in 2016. Since 2016 Dr. Hinton has continued as an Honorary Fellow and Visitor to the University of Melbourne and has continued research in the area of energy efficiency in telecommunications networks and services.

Abstract
Abstract: The tutorial will provide an introduction to the methods and applications required to understand and assess energy consumption of modern network equipment, networks and Internet services. This will include descriptions of technological trends in equipment power consumption, directions for future improvement and limits on what can be attained. The tutorial will also include several "use case" applications to provide attendees with concrete examples of how to assess the energy efficiency of networks and Internet services. It will also provide an overview of recent industry plans for improving the energy efficiency of the Internet.
Keywords: energy efficiency, telecommunications networks, sustainability, green networks
Aims and Learning Objectives: This tutorial will provide attendees a “bottom up” approach to understanding and assessing the energy consumption of telecommunications networks and Internet based services. This will provide course attendees a clear picture of the energy “eco-system” of telecommunications networks and services.
Target Audience: Engineers and other technologists with an interest in energy efficiency in telecommunications
Prerequisite Knowledge of Audience: A basic understanding of modern telecommunications networks.
Detailed Outline: This tutorial consists of the following sections:
- Motivation: Why should we be interested in energy efficiency in telecommunications?
• Traffic growth trends and the “efficiency gap”,
• ICT greenhouse gas emissions,
• Ubiquitous broadband, economic growth, Jevon’s Paradox and sustainability
o Case study: Australia’s National Broadband Network
- Energy consumption and efficiency metrics
- Estimating network energy consumption
- Equipment power consumption: measurement and models
• Switching & routing
• Transport
• Computation
• Trends
- Network power consumption
• Access network
• Edge & core network
• Data centres
• Storage & servers o Global Internet
- Energy efficiency and protocols
- Energy consumption of Cloud and Content Delivery services o Cloud & CDN eco-system
• Unshared & shared equipment
• Wireless cloud
• Interactive cloud services
o Cloud compared to local
• Content distribution
o IPTV
o Online Social Networks & photo sharing
• Cloud data storage
- Energy and the Internet of Things
- What can be done? (Addressing the efficiency gap)
• All optical signal processing
• The GreenTouch consortium
• The gap between theory and practice
- Summary & conclusions
