Routers vs Switches, How Much More Power Do They Really Consume? A Datasheet Analysis


This paper presents an analysis of a compiled database of power consumption and networking functionalities found in datasheets of routers and switches of some major manufacturers. We found very striking differences in consumption between switches and routers of the same nominal capacity. The paper analyzes the significance of such results and sheds some light on the most consuming elements and networking features that could be extremely useful in the re-planning and operation of energy-efficient networks.
