    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： A Clos-network packet switching system may include input modules coupled to a virtual output queue, central modules coupled to the input modules, and output modules coupled to the central modules, each output module having a plurality of cross-point buffers for storing a packet and one or more output ports for outputting the packet.
