Abstract |
In order to simplify the management of traditional networks, the software-defined networks (SDN) were proposed as a promising pattern which provide the programmability for the network configuration by separating two levels of control plane and data plane. By using and expanding SDN, the controller placement is considered as an important task in the software-defined networks. In the meantime, the allocation of switches to controllers plays a very important role in the quality of service (QoS). Afterwards, these criteria were used in the analytic hierarchical process(AHP) technique to fulfill the multi-criteria allocation of the switch to the controller, controller to controller as well as find the shortest. Eventually, the genetic algorithm of the controller placement was combined with the analytic hierarchical process technique to solve such a special problem of controller placement. The results represented that the allocative efficiency of this approach can reduce the link load balancing problem. In another word, the maximum link utilization of the route control was reduced. |
