To alleviate the growing concern of energy waste in networked devices, we propose an energy saving strategy in the ``server-centric" data center network. Focusing on servers, we introduce a basic scheme based on the transition of automata. By changing efficiently from sleeping state to active state in different network traffic, servers save the energy. This scheme is self-adaptive and simple...
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...
The use of network coding has been shown to improve throughput in input-queued multicast switches, but not without costs of computational complexity and delays. In this paper, we investigate the design of efficient online network coding algorithms in a switch with multicast traffic. We present Haste, an online opportunistic coding algorithm designed to streamline the computation when network coding...
Standard cell libraries are used extensively in CMOS digital circuit designs. In the past ten years, standard cell library size has increased by more than 10X. Reducing the library size is becoming a must. In this paper, we present an efficient piece-wise nonlinear library modeling format and library size reduction technique. Instead of using tables and vectors, this format uses base templates (curve...
