An 8X8multistage interconnection network(MIN) is constructed. Applying wavelength division multiplexing(WDM) technology and integrating control mode, the designed network can realize non-blockingcommunication. The time delay of the MIN and the switches needed are also analyzed in theory, thededuced result conforms that the MIN designed previously is feasible. In the case of the samecommunication quality guaranteed, MIN uses the least switches and completes the communication moreefficiently.展开更多
