An overview of a network-based model of power consumption in Internet infrastructure provides insight into how different parts of the Internet will contribute to network power as Internet access increase over time.Abstract:
This article provides an overview of a network-based model of power consumption in Internet infrastructure. This model provides insight into how different parts of the Internet will contribute to network power as Internet access increase over time. The model shows that today the access network dominates the Internet's power consumption and, as access speeds grow, the core network routers will dominate power consumption. The power consumption of data centers and content distribution networks is dominated by the power consumption of data storage for material that is infrequently downloaded and by the transport of the data for material that is frequently downloaded. Based on the model several strategies to improve the energy efficiency of the Internet are presented.read more

Attojoule Optoelectronics for Low-Energy Information Processing and Communications
TL;DR: This work shows that the next major interconnect dissipations are in the electronic circuits for receiver amplifiers, timing recovery, and multiplexing, and it can address these through the integration of photodetectors to reduce or eliminate receiver circuit energies, free-space optics to eliminate the need for timing andmultiplexing circuits, and using optics generally to save power by running large synchronous systems.

Reducing network energy consumption via sleeping and rate-adaptation
TL;DR: It is shown that even simple schemes for sleeping or rate-adaptation can offer substantial savings and that both sleeping and rate adaptation are valuable depending (primarily) on the power profile of network equipment and the utilization of the network itself.
