Abstract
The primary factors related to software-defined networks (SDN) deployment are the placement of the controller. The baseline issue encountered by network operators is to expand the network with reduced cost to fulfill the needs of substantial network users and to expand their services. To handle these issues, this work concentrates on implementing three different ideas for controller placement. The controller placement problem is dealt with the use of the Markov decision process, the implementation of multiagent aggregators for balancing network loads, and finally, game theory is performed to show effectual controller placement. The current network model is reorganized with metrics like delay, packet loss, and throughput. These metrics are measured before and after the installation of controllers. As this network expansion problem is more generalized, these approaches can be applied to perform newer network functionalities by updating the existing network model.KeywordsSoftware-defined network (SDN)Controller placementMarkov decision processMultiagent aggregatorGame theory
