In this thesis, we present a high performance fault tolerant switch for B-ISDN, called the Reliable and Zealous Network (RAZAN). It consists of N Log2N switching elements of size n + 1 usd\timesusd n + 1, where N is the number of inputs and n = Log2N is the number of stages. The performance of the network is evaluated analytically as well as through simulation under uniform traffic load. RAZAN shows a high throughput in the presence or absence of faults compared to a number of recently introduced networks. Moreover, RAZAN has a high terminal reliability even for large network sizes. The architecture of RAZAN also offers high fault tolerance, in-sequence delivery of cells, simple routing, and regularity.
