ABSTRACT
A Software Defined Network is different from traditional networks because of its flexible and developable structure. This structure gives the researchers the opportunity to perform computational tests in their environments with realistic results. Software Defined Networks provide an extremely flexible environment for researchers. Network topology measurement, network traffic analysis, and network performance computations are performed on virtual networks created with the Mininet emulator. In this study, the Bellman-Ford routing algorithm was adapted into the routing module of the Floodlight controller. Then TCP traffic on a medium-sized network topology was generated and the traffic performance results were obtained in between the nodes even in different subnets. The implementation results were compared with the default routing algorithm of Floodlight, namely Dijkstra’s algorithm.
