Abstract

In this paper, future requirements we believe that will be needed for achieving power efficient routers are shown. The optical backplane is a proposal technology we are working on, which enables a high-speed and power efficient data transmission in backplane of routers and switches, by connecting the electronic devices together with optical paths. It is effective for edge routers and switches which are growing in size with very large throughput that need heavy clustering. According to our estimation, the power efficiency will improve for around 20 percent in total; power consumption in routers. Dynamic performance control is a technology in the system layer. By controlling the performance of the router or switch according to the amount of traffic, the power that is cast away will be decreased. The combination of these technologies will improve the power efficiency for routers and switches.
