To achieve this goal, the method of placing controllers based on both Djikstra's algorithm and K-means algorithm was chosen, and experimental results indicate that this method provides better performance and can be easily implemented for a variety of applications.enSoftware Defined Network, Controller, Controller Problem PlacementThesis
