[Paper Title, Abstract] Improving Latency in Traffic Prediction Based Energy-aware Routers Show AbstractHide Abstract For green networking, Sliced Router Architecture was proposed which controls power consumption of routers by adjusting routers’ performance based on the volume of traffic. In this architecture, any packet losses can be eliminated but it leads a significant increase of processing latency in some cases, which is also a serious performance degradation of routers. In this paper, we propose two extensions in Sliced Router Architecture to achieve both zero packet loss and low latency which satisfies the requirement in current common routers. We first propose parallelized prediction counters for improving accuracy of prediction. Moreover, we extend the prediction circuit to support multiple prediction functions which derive the number of active slices continuously or supplely to reduce traffic latency under the conditions of keeping no packet loss. We then perform the simulation to evaluate the improvements in prediction accuracy, and the trade-off in power-saving and worst traffic latency. Our results show that the power efficiency can increase up to 3.4% by introducing parallelized counters, and achieve 156 microseconds of the processing latency by accepting 21.1% increase of power consumption.
