本文对有关互连网络拓扑等价的分析方法作了简单评述。并采用互连网络拓扑等价的图分析法分析了自由空间光学互连全交叉网络与ＳＷ榕树网络的拓扑等价及其多样性，拓展了全交叉网络在数字光计算、光子交换及多处理机系统的潜在应用。 This article gives a brief review of the equivalent analysis methods for interconnecting network topologies. The topological equivalence and diversity of the free-space optical interconnection full-cross network and the SW-Banyan network are analyzed by the graph analysis method of interconnected network topological equivalence. The full cross-connect network is expanded in digital light computation, photon exchange and multiprocessing Potential applications of machine systems.
