为了避免完全无阻塞型crossbar网络拓扑结构复杂、硬件成本高的缺点,以及可重排无阻塞型多级光互连网络链路函数不一致引起的光学实现困难等问题,提出和设计具有相同链路结构的多级光互连网络,对其拓扑结构进行详细的分析与比较,将其路由算法进行优化,并用于8×8omega+omega网络的路由判断和节点状态的确定。结果表明,该多级混洗光互连网络具有结构简单、操作性强、控制灵活、路由算法时间短、路径选择简并度高和易扩容升级等特点,能够实现输入信号的完全无阻塞输出与排序。
In order to avoid the problems of complex non-blocking crossbar network topology, high hardware cost and difficult optical implementation caused by inconsistent link function of non-blocking multi-level optical interconnection network, a new design scheme with the same link Structure of multi-level optical interconnection network, the topology of its detailed analysis and comparison, the routing algorithm is optimized and used in 8 × 8omega + omega network routing and node status determination. The results show that the multi-level shuffled optical interconnection network has the advantages of simple structure, strong operability, flexible control, short routing algorithm time, high degeneracy of path selection, easy expansion and upgrade, and the like, and can achieve complete non-blocking output of the input signal With sort.
