Optimal Design of Switch Sizes in Strictly Non-Blocking Clos Three-Stage Interconnection Networks
Esmaeel Zeinali Kh., Mehdi N. Fesharaki and Mohammad Teshnehlab

Abstract:
In this study, a simple method for optimal design of switch sizes in strictly non-blocking Clos three-stage interconnection network is presented. The numerical results show that the switch sizes of optimal multistage interconnection networks can be calculated very fast for any practical multistage interconnection network sizes. In other words, computes the optimal parameters that are required for selecting the switch sizes for all sizes of practical multistage interconnection networks. Because of the optimal selection of the switch sizes, the final results show a decrease in the crosspoints as well as the complexity of the internal connections of the interconnection network. It is also shown that when the number of inputs and outputs in the network changes, the number of inputs for the first stage and of the outputs for the third stage become equal. So the only parameter that undergoes changes is the number of switches. Therefore, the size of switches in a network proves to be independent from the total number of inputs and outputs in a network. In other words, if the total number of inputs changes, the size of switches will be fixed whereas the number of them will change.
