针对地理分布的光网络的脆弱性,构建了基于恢复技术的光网络脆弱性能评估模型,利用基于参数i二分查找法计算最大流量的最小值,得出光网络的脆弱区域。仿真结果表明,该方案得出的结果与其他文献报道的相比,能够有效地计算光网络的脆弱区域,同时降低了算法的事件复杂度。 Aiming at the fragility of geographically distributed optical networks, an evaluation model of optical network vulnerability based on restoration technology is constructed. The minimum value of maximum traffic based on parameter i dichotomy is used to obtain the fragile area of ​​optical networks. The simulation results show that the proposed scheme can effectively calculate the fragile area of ​​optical network and reduce the complexity of the algorithm compared with other reported results.
