DbDest: an efficient, high-performance, fault-tolerant fabric for broadband ISDN

We develop a new switch architecture, DbDest, that can offer multiple paths from each input to each output with small hardware cost and is able to support a wide range of services with diverse traffic characteristics. Our simulations show that DbDest can accomplish the same or better performance than existing switching architectures but with only half the hardware cost of the parallel banyan networks. As the DbDest network size increases, the performance-cost ratio improves
