Internet is built as a packet-switching network. The kernel function of Internet infrastructure, including routers and switches, is to forward the packets that are received from one subnet to another subnet. The packet forwarding is accomplished by using the header information extracted from a packet to look up the forwarding table maintained in the routers/ switches. Due to rapid growth of net...

Energy efficiency is of the utmost importance in modern high-performance em-bedded processor design. As the number of transistors on a chip continues to in-crease each year, and processor logic becomes ever more complex, the dynamicswitching power cost of running such processors increases. The continual progres-sion in fabrication processes brings a reduction in the feature size...

In this chapter we present an energy-efficient highly adaptive network interface architecture and a novel data link layer protocol for wireless networks that provides Quality of Service (QoS) support for diverse traffic types. Due to the dynamic nature of wireless networks, adaptations in bandwidth scheduling and error control are necessary to achieve energy efficiency and an acceptable quality...

The energy consumption in telecommunication networks is expected to grow considerably, especially in core networks. In this chapter, optimization of energy consumption is approached from two directions. In a first study, multilayer traffic engineering is used to assign energy-efficient paths and logical topology to IP traffic. The relation with traditional capacity optimization is explained, an...
