Energy efficiency in the load-balanced switch

Since the inception of the load-balanced switch, its elegant scheduling with 100% throughput has attracted a substantial amount of research interest. In this paper, we further investigate the energy consumption issues in the load-balanced switch based on the rate region analysis. We propose a self-adapting sleeping algorithm, not only providing throughput guarantee, but also taking advantages of period inactivity of traffic, while keeping the elegancy of load-balanced switches. We have collected real traffic trace on campus, which indicates 83% energy in the line cards could be saved in our proposed algorithm.
