Optimization of control plane in a software defined network includes obtaining peer information of at least one neighbouring network controller by a network controller and determining a traffic profile variation. The method further includes computing of a self payoff value indicative of one of optimum utilization, underutilization and overutilization of the network controller. The method further includes initiating a non-zero sum game based network control plane optimization operation based on the self payoff value and the traffic profile of the neighbouring network controllers, and may include one of activating additional network controller(s), transferring control of one or more network devices managed by the network controller(s) to a neighbouring greedy network controller, deactivating the network controller, and transferring control of one or more additional network devices managed by the neighbouring network controller(s) to the greedy network controller. |

1. A method for optimization of a control plane comprising network controllers in a communication network, the method comprising:
obtaining, by a network controller, peer information of at least one neighbouring network controller, wherein the peer information is indicative of utilization and delay associated with performance of the at least one neighbouring network controller; determining, by the network controller, a traffic profile variation, wherein the traffic profile variation is indicative of changes in a current traffic profile of the network controller and the at least one neighbouring network controller with respect to a previous traffic profile of the network controller and the at least one neighbouring network controller; computing, by the network controller, a self payoff value for the network controller, wherein the self payoff value is indicative of one of optimum utilization, underutilization and overutilization of the network controller, and wherein the computing is based on predefined QoS parameters; and initiating, by the network controller, a non-zero sum game based network control plane optimization operation based on the self payoff value and the traffic profile of at least one neighbouring network controller, wherein the non-zero sum game based network control plane optimization operation comprises one of: activating at least one additional network controller, transferring control of one or more network devices managed by the network controller to the at least one neighbouring network controller, deactivating the network controller, and transferring control of one or more network devices managed by the at least one neighbouring network controller to the network controller. |
