| Abstract: | Software-Defined Networking (SDN) builds a new network paradigm through the separation of the control plane from the data plane and the logically centralized control. Considering the requirements of performance, scalability and reliability, large-scale networks usually adopt a distributed SDN control plane, i.e., placing multiple controllers to manage the whole network. In order to optimize the performance, reliability, cost and energy consumption of the network, it is necessary to determine the number and locations of controllers and the assignment between switches and controllers; that is known as controller placement problem. This paper systematically studies distributed SDN controller placement problem. Firstly, the various optimization metrics of controller placement problem are introduced in detail. Secondly, the controller placement schemes proposed by existing researches are classified, analyzed and summarized according to the optimization objectives and the trade-offs among these objectives. Finally, we discuss the future research trends in controller placement problem. |
