Blocking in multirate interconnection networks

Presents 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 using Benes networks as an example. Extensive simulation has been performed focusing on ways to reduce blocking to acceptable levels. The author found that the major factors affecting blocking are switching element size, speed advantage of the switch fabric, routing algorithms and connection bandwidth.<
