Abstract: In software defined networking (SDN) when the number of network elements and traffic flows escalate, a single controller cannot efficiently handle the growing load, resulting in the deployment of multiple controllers. To develop computationally less intensive solutions for the controller placement problem in WAN, clustering-based network partitioning algorithms can be employed. The proposed method partitions the network using a modified-AP clustering algorithm which automatically computes the number of clusters and uses the candidate exemplars identified for the placement of SDN controllers. The similarity measure that considers both the Euclidean distance and link bandwidth is the input to the proposed algorithm, and the simulation is carried out using standard network topologies from the Internet Topology Zoo. The simulation results show that the observed number and location of SDN controllers minimises average case, worst-case, inter-controller latency and improved controller imbalance factors which ensure the optimal number and placement of SDN controllers.
