The fast progress in the network technologies required the network environment to be fast and reconfigurable flexibly which make the network more dynamic, scalable, programmable and manageable. Software Defined Network (SDN) is suggested to find solution for all problems of previous network forms, by separating the control plane from data plane and provided centralized controlling to manage the whole network. This paper makes study about the implementation of FatTree network topology. Then shows the main idea of OpenFlow protocol that can be applied on FatTree network topology by using SDN technology and how that can be effect on the performance of overall network and make it more flexible to enable the SDN module application, like Quality of Service (QoS) for improving the SDN network. In this paper the physical switches (network equipment) are replaced by software switches in a virtual network environment and display the SDN structure in GUI, also the Floodlight controller is chosen to perform this works and to use as the Network Operating System (NOS) for SDN network.
