Literature survey on traffic-based server load balancing using SDN and open flow

At large data centers, server load balancing is used to balance the incoming requests among the servers to avoid excessive overloading of any individual server. However the present methods are static and suffer from many drawbacks. Static methods do not offer an even balance of data among servers and require dedicated hardware for load balancing. Hence, dynamic methods are required to enhance the load balance of server. Dynamic method provides load balancing of server inclusion of the dynamic state of traffic on the network. In this paper, the need for dynamic load balancing methods of SDN is discussed and provided with the literature survey of the existing static load balancing schemes.
