FCMCP: Fuzzy C-Means for Controller Placement in Software Defined Networking

Abstract

One of the most critical factors in SDN networks is the controller placement. The controller’s location determines the network delay. Reduction in network latency can help to scale the network effectively. A Fuzzy C-Means approach is used for placement of controller in optimized manner to improve the network latency. A topology-zoo network data-set, such as OS3E and Chinanet, were used to validate the proposed FCMCP. This technique offers faster response time than K-Clustering methods such as K-Center, K-Mean, etc. Finally, the Fuzzy C-Means method reduces latency by 18% when compared to the K-Clustering methods.
