Abstract
A routing controller (30) includes an interface (68) and multiple processors (60). The interface is configured to receive a permutation (76) defining requested interconnections between N input ports and N output ports of a Benes network (24). The Benes network includes multiple 2-by-2 switches (42), and is reducible in a plurality of nested subnetworks associated with respective nesting levels, down to irreducible subnetworks including a single 2-by-2 switch. The multiple processors are configured to collectively determine a setting of the 2-by-2 switches that implements the received permutation, including determining sub-settings for two or more subnetworks of a given nesting level in parallel, and to configure the multiple 2-by-2 switches of the Benes network in accordance with the determined setting.
