We introduce an application in network computing/control/storage network, including a node controller chip of routing & switching array and a prototype design and implementation. The routing & switching array system uses software defined network (SDN) through the Internet to realize the integrated programming control on the inner routing control and security module of the high speed secure switching network, so as to meet the need of the data center for data transmission bandwidth capacity. Besides, we alleviate and eliminate the bottleneck of network transmission of the parallel computing process, thus avoiding the waste of longterm occupation of network data center resources and laying a foundation for the solutions of next generation data centers. In addition, we briefly introduce the current  research situation of its application in the financial transaction system.
