Announcing the Keynote Line-up for ComSoc's First Online
Conference on Energy-Efficient Communications & Green Technologies

The Value of the True Green Data Center

In today's Data Center, power planning and power management are rapidly becoming the key to sustainable growth. Many Data Centers are limited in their ability to bring additional power and cooling to bear due to physical grid limitations; others are economically limited as the cost of power has skyrocketed. This presentation will discuss multiple power savings strategies in the Data Center, including: consolidation of separate Networks (Storage, Networking and Low Latency), consolidation of multiple 1Gb links into a smaller number of 10GbE links, the use of Energy Efficient Ethernet and System-level offload capabilities. Session attendees will learn which power-saving technologies have the most impact and/or are easiest to implement, and understand how to prioritize various power-saving measures as part of an overall green data center plan.

Green Communications and Cloud Computing

Today's Internet consumes approximately 1% of the world's electricity, and data centres and cloud computing infrastructure consume an additional 2%. These percentages might seem small, but they are growing rapidly as the telecommunications network and cloud computing infrastructure expands to meet the ever-increasing demands for more Internet services. In this talk, I will examine the key contributors to energy consumption in the Internet and cloud computing, and examine some future scenarios for network growth. The energy consumption of the network is currently dominated by access networks, both wired and wireless, but the energy consumption of routers and switches in the network is rising rapidly, and could eventually dominate over the access network. In estimating the energy consumption of future networks, it is useful to consider the theoretical lower bounds on energy in transport and switching. I will explore the gap between these theoretical lower bounds and the actual energy consumption in today's network energy efficiencies, and examine how this gap might be closed.

Communication Networks & Sustainability

Communication technologies provide powerful tools that can enable us to better monitor and control energy use across society. At the same time, such technology is a driver for economic growth, which brings with it the threat of increased energy consumption. The carbon footprint of the network infrastructure itself, which expands with the Internet, must be contained in the face of increasingly difficult challenges related to electronic and photonic component scaling. Will increases in network efficiency help to control energy consumption or further fuel unsustainable, near exponential growth? I will examine global energy trends related to communication networks and point to key issues that are expected to shape future networks. The complex relationship between carbon footprint and energy efficiency will be considered in the context of achieving long term sustainable solutions.
