Energy efficient solutions for the networks and routers

Under the pressure of the global CO2 emission, energy efficiency is one of the most important aspects that need considerations in designing the future Internet. For reducing the power consumption of the Internet, people should focus their research attentions on the power-aware networks design and most power consuming networking devices such as routers. This paper overviews a number of promising solutions in recent years for reducing the energy consumption of the networks and routers. Moreover, we present our research achievement about an energy efficient networking forwarding node on the NetFPGA platform by combining the salient advantages of the Bloom filter based publish/subscribe forwarding node and frequency scaling. Our findings show that the frequency scalable Bloom filter (zFilter) forwarding node can not only improve the forwarding performance, but also considerably reducing the power consumption of the router.
