Approximate Non-blocking Permutation Three Stage Clos Network
Proposed a methed for designing a three stage Clos network with small blocking probability and low hardware.Through the tradeoff between blocking probability and hardware cost,The three stage Clos network model with small blocking probability and low hardware is obtained when the probability that a port is busy is not very big,and the case when the probability is big that a port is busy is also analysed and discussed.Finally,by the comparison between different size of network,it can be concluded that the hardware cost of the designed network is less approximate 50% than that of corresponding strictly non-blocking network but the probability is very small.
