A new class of switching topologies known as Extended Generalized Shuffle EGS networks is presented, and we show that the flexibility of these network makes them well-suited for photonic switching applications. We then analyze the hardware costs S-SEED arrays and various operating characteristics blocking probability, fault-tolerance, and system downtime of these network topologies. We also present a new type of switching node a 2-module for use in EGS networks, and we show that 2-modules can be efficiently implemented using available optical logic devices. It is shown that an optical implementation of these networks may yield a cost-effective way to capitalize on the bandwidth and parallelism of free-space optics.
