摘要：Software defined network (SDN) decouples the control plane from packet processing device and introduces the controller placement problem. The previous methods only focus on propagation latency between controllers and switches but ignore either the latency from controllers to controllers or the capacities of controllers, both of which are critical factors in real networks. In this paper, we define a global latency controller placement problem with capacitated controllers, taking into consideration both the latency between controllers and the capacities of controllers. And this paper proposes a particle swarm optimization algorithm to solve the problem for the first time. Simulation results show that the algorithm has better performance in propagation latency, computation time, and convergence. © Springer International Publishing Switzerland 2015.
