New structures of the optical node in multihop transparent optical networks with deflection routing

New single-receiver/single-transmitter/single node structures for two-connected multihop transparent optical packet-switching networks with deflection routing are introduced. A ShuffleNet topology in uniform traffic is adopted to compare various shared optical memory schemes and their control algorithms. These simple structures minimize the number of crossbar switches needed or the node and have moderate control complexity, while still yielding high throughput and low delay. Analytical results are obtained by an extension of the existing theory and verified by simulation.<
