A Framework for Energy Aware Routing in Packet Networks

Free registration required

Executive Summary

The increasing importance of wired packet networks as the transport substrate on which many communication technologies are converging also increases the importance of making these networks efficient in different aspects. A major need for greater efficiency is in the power consumption of such networks, which can be improved in several ways. The energy efficiency of all the equipment that is used in networks is of primary concern and equipment manufacturers as well as chip designers are increasingly aware of this problem. One could also examine the manner in which the network topology can be designed so as to optimise for energy efficiency within a desired framework of traffic load and Quality of Service (QoS) constraints.
