In the modern era, Network Management is becoming so complex with several networking devices like switches, routers and middle boxes for manipulating network traffic for different purposes. Software Defined Networks is a new archetype that meets the ossifying needs of the network. It separates the control plane from the data plane of forwarding devices by introducing a controller that brings the idea of programmable network. This paper suggests a dynamic load balancing scheme for a server farm using the concepts from SDN. The proposed work introduces two mediators' named Load mediator and Channel mediator, which will control the server load by updating the Load status table in the controller systematically. The proposed method has been implemented and compared with popular load balancing schemes like Round Robin and Random algorithms.
