Abstract

A switch network for switching network inputs to network outputs includes an initial terminal, an intermediate, and a final terminal layer of switches. The initial terminal layer of switches provides fan-out of the network inputs to widely separated locations in the intermediate layer. The intermediate layer of switches includes two sublayers: a first sublayer providing horizontally aligned fan-outs to the final terminal layer of switches and a second sublayer providing vertically aligned fan-outs to the final terminal layer of switches. The final terminal layer of switches includes a left sublayer and a right sublayer. The left sublayer provides fan-in from the vertically aligned fan-outs and the horizontally aligned fan-outs to the network outputs; the right sublayer provides fan-in from the vertically aligned fan-outs and the horizontally aligned fan-outs to the network outputs; and the fan-in provided by the left sublayer is orthogonal to the fan-in provided by the right sublayer.
