Load Balancing Algorithm in a Software-Defined Network Environment with Round Robin and Least Connections

In a traditional computer network, each device has its configuration. The Software Defined Network (SDN) architecture ensures that every device in the network will become a dummy device, which must connect to a controller before action can be taken on every packet that the device receives. Each device does not require manual configuration with the centralized configuration. The huge growth of internet traffic can affect the server’s performance when handling requests of many clients. The algorithms, such as Round Robin and Least Connection, influence the load-balancing technology to divide the request to some servers. The server’s performance increases after implementing load balancing with the algorithm in testing. The comparative result of the Round Robin and Least Connection algorithms shows that the Least Connection performs better than the Round Robin algorithm. By using load balancing in the SDN architecture, the increasing of the request capacity can be handled by the server.
