Load Balancing of SDN Controller for Migration Optimization Based on Metaheuristics

With the existing power SDN network architecture, improved switches migration algorithm is put forward. Through advantages of ant colony and genetic fusion, process optimized, fusion in uses operation, such as restrictions advance pruning efficiency to eventually apply under multiple controllers switch. The stability switch multicontroller are improved, performance RYU controller compared with other algorithms. results comparison test show that reduced by 12.5% 1.5%, which a response delay; accuracy operation can make full use resources achieve purpose improving load balancing among controllers.
