In SDN, the control logic is separated from network devices such as routers and switches. Accordingly, network devices only need to transfer data (data layer), while the control logic is handled by a central controller. In this paper, we propose a controller placement strategy for SDN in WAN. Our scheme can allocate multiple controllers in each SDN domain of WAN by the number of nodes of each SDN domain. The controllers are placed according average minimized latency and get the good performance.
