Managing energy consumption costs in desktop PCs and LAN switches with proxying, split TCP connections, and scaling of link speed

Abstract The IT equipment comprising the Internet in the USA uses about 6 billion of electricity every year. Much of this electricity use is wasted on idle, but fully powered‐up, desktop PCs and network links. We show how to recover a large portion of the wasted electricity with improved power management methods that are focused on network issues. Copyright © 2005 John Wiley & Sons, Ltd.
