摘　　要：为全面评估通信路径性能,提升数据传输的可靠性与稳定性,研究考虑数据传输成功率的光网络最优通信路径选择方法。以最大化数据传输成功概率与最小化数据传输超时概率为目标函数,建立光网络最优通信路径选择模型;蚁群算法依据选择概率,生成初始光网络最优通信路径选择模型的可行解集合;利用遗传算法对可行解集合进行选择、交叉与变异处理,得到新的最优通信路径选择模型可行解集合;通过数据传输成功概率与超时概率,设计遗传算法的适应度,以最优适应度对应的可行解集合为最终可行解集合;利用蚁群算法在最终可行解集合内,选择最大数据传输成功概率,以及最小超时概率对应的最优通信路径。实验证明:该方法可有效生成初始光网络最优通信路径模型的可行解集合,并完成最优通信路径选择,提升数据传输成功概率,降低数据传输超时概率;应用该方法后,光网络的网络状态指示值较高,即光网络的整体性能较优。In order to comprehensively evaluate the performance of communication path and improve the reliability and stability of data transmission,the optimal communication path selection method of optical network considering the success rate of data transmission is studied.Based on the objective function of maximizing the probability of data transmission success and minimizing the probability of data transmission timeout,the optimal communication path selection model of optical network is established.The ant colony algorithm generates the feasible solution set of the optimal communication path selection model of the initial optical network according to the selection probability.Genetic algorithm is used to select,cross and mutate the feasible solution set,and a new optimal communication routing model feasible solution set is obtained.According to the success probability and timeout probability of data transmission,the fitness of genetic algorithm is designed,and the feasible solution set corresponding to the optimal fitness is the final feasible solution set.The ant colony algorithm is used to select the optimal communication path corresponding to the maximum probability of data transmission success and the minimum timeout probability in the final feasible solution set.Experimental results show that the proposed method can effectively generate the feasible solution set of the optimal communication path model of the initial optical network,complete the optimal communication path selection,improve the probability of data transmission success,and reduce the probability of data transmission timeout.After this method is applied,the network status indicator value of the optical network is higher,that is,the overall performance of the optical network is better.
