    摘要: A Pipelined-based Maximal-sized Matching (PMM) scheduling approach for input-buffered switches relaxes the timing constraint for arbitration with a maximal matching scheme. In the PMM approach, arbitration may operate in a pipelined manner. Each subscheduler is allowed to take more than one time slot for its matching. Every time slot, one of them provides the matching result. The subscheduler can adopt a pre-existing efficient maximal matching algorithm such as iSLIP and DRRM. PMM maximizes the efficiency of the adopted arbitration scheme by allowing sufficient time for a number of iterations. PMM preserves 100% throughput under uniform traffic and fairness for best-effort traffic.

    摘要: Methods and apparatus for packetized energy distribution are provided. A data and power delivery network, called a digital grid, is provided to facilitate delivery of power upon request. Energy bits (quanta) serve as a means to deliver energy as well as coding. Voltage pulses of varying time scales are used for coding and current levels help to accurately meet customer's demand. Energy is sent as packets (a combination of energy bits), and specific energy packets are addressed to specific customers permitting accurate monitoring and distribution of electrical energy.

    摘要: A configuration scheme for IQC switches that hierarchizes the matching process reduces configuration complexity by performing routing first and port matching afterwards in a three-stage Clos-network switch. This scheme applies the reduction concept of Clos networks to the matching process. This, in turn, results in a feasible size of schedulers for up to Exabit-capacity switches, an independent configuration of the middle stage modules from port matches, a reduction of the matching communication overhead between different stages, and a release of the switching function to the last-stage modules in a three-stage switch. The switching performance of the proposed approach using weight-based and weightless selection schemes is high under uniform and non-uniform traffic. The number of stages of a Clos-network switch can be reduced to two.

    摘要: Multicast traffic is expected to increase in packet networks, and therefore in switches and routers, by including broadcast and multimedia-on-demand services. Combined input-crosspoint buffered (CICB) switches can provide high performance under uniform multicast traffic. However this is often at the expense of N2 crosspoint buffers. An output-based shared-memory crosspoint-buffered (O-SMCB) packet switch is used where the crosspoint buffers are shared by two outputs and use no speedup. An embodiment of the proposed switch provides high performance under admissible uniform and non-uniform multicast traffic models while using 50% of the memory used in CICB switches that has dedicated buffers. Furthermore, the O-SMCB switch provides higher throughput than an existing SMCB switch where the buffers are shared by inputs.
