Aims
ICT is a direct contributor to more than 2% of global CO2 emissions, and this is expected to double in the near future. Networks are a large part of the overall energy consumption of ICT. Energy consumption of networks is both direct (from network links and equipment) and induced (from hosts forced to remain in a higher power state to maintain connectivity). In this series of lessons, we will cover the energy consumption of ICT, explore current research in reducing both direct and induced energy consumption of networks, briefly explore future directions where networks can enable the reduction of energy consumption in other sectors of the economy, and review ongoing green network standards, initiatives, and products. It will be seen that green networks offer the researcher a range of modeling and systems problems. The primary focus of this course will be on the Internet and the network equipment and hosts that connect to it where large savings can be achieved (as such, energy issues specific to cellular networks and wireless ad hoc and sensor networks are not covered).
