An optimal communication path selection method for optical networks considering the data transmission success rate
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 transmis-sion is studied.Based on the objective function of maximizing the probability of data transmission success and minimizing the probabil-ity of data transmission timeout,the optimal communication path selection model of optical network is established.The ant colony algo-rithm 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 communica-tion 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 solu-tion 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,com-plete the optimal communication path selection,improve the probability of data transmission success,and reduce the probability of da-ta transmission timeout.After this method is applied,the network status indicator value of the optical network is higher,that is,the o-verall performance of the optical network is better.
