Based on the link rule and the function principle of the banyan network,its corresponding processing matrix has been achieved to denote and illustrate the relative signal operating and controlling. In other words,the matrix computing is employed to replace the complicated control process of optical network. Furthermore,extend the results of the two-dimensional banyan network to three-dimensional space in terms of the relative mapping rule of banyan network,the performing matrix has also been attained to solve some problems such as node controlling,signal routing,etc. The simple truth is that the ability to replace the complex process of optical interconnection network using the matrix computing opens the door to a host of new and exciting opportunities including signal routing and node switch controlling. The results indicate that this method may be useful for optical switching applications,optical computing,and optical information processing.
