摘　　要：光学全交叉网络广泛应用在光纤通信中,为了提高网络的覆盖范围和通信能力,进行网络拓扑结构稳定性设计,提出一种基于邻居节点多链路分布式拓扑的光学全交叉网络拓扑结构。首先对光学全交叉网络的拓扑结构层次模型进行分析,建立节点分布路由链路模型,然后采用双向链路估计模型进行路由拓扑协议设计,通过多链路分布式拓扑算法进行路由冲突的反演控制,综合全网的能量和负载均衡实现拓扑结构稳定性设计。最后进行仿真分析,结果表明,采用该方法进行拓扑结构设计,提高了光学全交叉网络的信息准确传递率,降低了传输延迟,网络结构的稳定性和鲁棒性增强。Optical crossover networks are widely used in optical fiber communication, in order to improve the cov- erage and communication capacity of the network, design the stability of the network topology. This paper proposes a optical crossover network topology structure based on neighbor nodes multi-link distributed topology. First analyzes the topological structure model of optical crossover network, establishes nodes distributed routing link model. Then uses bi- directional link estimation model to design routing topology protocol, controls routing conflict inversions through muhi- link distributed topology algorithm, integrates the balances of network energy and load to achieve topology stability de- sign. Finally, simulation results show that this design improves information transmission rate accuracy, reduces trans- mission delay, and enhances structure stability and robustness.
