A study is made of an extension of the classical methods used to evaluate blocking probability. This method is applicable to multirate circuit and fast packet/ATM switching systems. The analytical methods are presented and compared with simulation results for Benes networks. Extensive simulation has been performed examining blocking in Benes networks. These simulations focus on ways to reduce blocking to acceptable levels. It is found that the major factors affecting blocking are switching element size, speed advantage of the switch fabric, routing algorithms and connection bandwidth. >
