Abstract: Software defined networking (SDN) architecture has been verified to make the current network architecture management simpler, and flexible. The key idea of SDN is to simplify network management by introducing a centralized control, through which dynamic updates of forwarding rules, simplification of the network devices task, and flow abstractions can be realized. In this article, the researchers discuss the complex design of the current network architecture, which has inevitably resulted in poor network resources management, such as bandwidth management. SDN-based network model has been proposed to simplify the management of the limited bandwidth of a network. The proposed network model utilizes the limited network bandwidth systematically by giving real-time traffics higher priority than non-real-time traffics to access the limited resource. The experimental results showed that the proposed model helped ensure real-time traffics would be given greater priority to access the limited bandwidth, where major portion of the limited bandwidth being allocated to the real-time traffics.
