Energy consumption and the concomitant Green House Gas (GHG) emissions are becoming major issues in modern industrial society. In this scenario, current high performance network infrastructures (routers, switches, line cards, signal re-generators, optical amplifiers, etc.) have reached huge bandwidth capacity but their development has not been compensated at the same rate as for their energy consumption. It is estimated that such infrastructures alone consume 22GW of electrical power corresponding to more than 1% of the world wide electrical energy consumption, with a power consumption growth rate of 12% per year, further stressing the need for energy-efficient network devices and energy aware routing protocols and control planes. Analogously, the ever-increasing data volumes to be processed, stored, and accessed every day in modern data centers result in an energy demand growing a faster and faster pace. Data center power and cooling infrastructure worldwide waste more than 60 million MW hours per year of electricity that does no useful work powering IT equipment. This represents an enormous financial burden on industry and is a significant public policy environmental issue. Renewable energy sources are emerging as promising solution both to drastically reduce GHG emissions and to cope with the growing power requirements of these infrastructures, due to their lower energy costs. In particular, the dynamic distribution of computing and storage load in multiple data centers scattered throughout the world can be investigated in order to exploit the availability of renewable energy sources and lower their ecological footprint and contain the energy-related bills. Therefore, new energy-aware paradigms relying on smart grid infrastructure are emerging, able to either divert the network traffic on energy-efficient equipment or, analogously, to direct computing tasks or the data towards a site which is currently green powered (thus, in a follow-the-renewable energy manner), or to request to the smart grid a quantity and quality of energy (e.g., from an available renewable energy production site) for the facility (in a follow-the-data manner). Such energy-aware paradigms unveil new potentials for the ICT that have not been explored before. The main objective of this lecture is presenting the current challenges and research trends for eco-sustainable ICT infrastructures and the new energy-aware networking and computing models, protocols, architectures, techniques and paradigms that, considering power usage as a new constraint, optimize the use of energy and reduce the GHG emissions for achieving a more sustainable society that will be a basis for growth and prosperity. Also, some emerging energetic attacks to data centers and mobile equipments are presented.
Aniello Castiglione (S' 04–M' 08) received the Ph.D. degree in Computer Science from the University of Salerno (Italy).
