| Summary: | 碩士 === 大同大學 === 資訊經營學系(所) === 105 === Software-defined networking (SDN) is a new network model, and it changes the current limit network facilities. 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.
