Abstract

Novel single-receiver/single-transmitter/single-buffer node structures for ultrafast two-connected multihop transparent optical packet-switching networks with deflection routing are introduced. A Shufflenet topology in uniform traffic is used as a benchmark to compare several shared optical memory schemes and their control algorithms. These simple structures minimize the number of crossbar switches needed at each optical node and have moderate control complexity, while still yielding large throughput and small delay. The minimization of the number of crossbar switches results in an improved optical power budget. An analytical model, obtained by an extension of the existing theory, provides a design tool to search for efficient node control strategies that minimize the number of deflections and packet misses for each constrained node structure.
