Energy consumptionand the concomitant Green House Gas (GHG) emissions are becoming major issuesin modern industrial society. In this scenario, current high performancenetwork infrastructures (routers, switches, line cards, signal regenerators,optical amplifiers, etc.) have reached huge bandwidth capacity but theirdevelopment has not been compensated at the same rate as for their energyconsumption. It is estimated that such infrastructures alone consume 22 GW of electricalpower corresponding to more than 1% of the worldwide electrical energyconsumption, with a power consumption growth rate of 12% per year, furtherstressing the need for energy-efficient network devices and energy awarerouting protocols and control planes. Analogously, the ever-increasing datavolumes to be processed, stored, and accessed every day in modern data centersresult in an energy demand growing a faster and faster pace. Data center powerand cooling infrastructure worldwide waste more than 60 million MW hours peryear of electricity that does no useful work powering IT equipment. Thisrepresents an enormous financial burden on industry and is a significant publicpolicy environmental issue. Renewable energy sources are emerging as promisingsolution both to drastically reduce GHG emissions and to cope with the growingpower requirements of these infrastructures, due to their lower energy costs.In particular, the dynamic distribution of computing and storage load inmultiple data centers scattered throughout the world can be investigated inorder to exploit the availability of renewable energy sources and lower theirecological footprint and contain the energy-related bills. Therefore, newenergy-aware paradigms relying on smart grid infrastructure are emerging, ableto either divert the network traffic on energy-efficient equipment or,analogously, to direct computing tasks or the data towards a site which iscurrently green powered (thus, in a follow-the-renewable energy manner), or torequest to the smart grid a quantity and quality of energy (e.g., from anavailable renewable energy production site) for the facility (in afollow-the-data manner). Such energy-aware paradigms unveil new potentials forthe ICT that have not been explored before. The main objective of this lectureis presenting the current challenges and research trends for eco-sustainableICT infrastructures and the new energy-aware networking and computing models,protocols, architectures, techniques and paradigms that, considering powerusage as a new constraint, optimize the use of energy and reduce the GHGemissions for achieving a more sustainable society that will be a basis forgrowth and prosperity. Also, some emerging energetic attacks to datacenters andmobile equipments are presented.
