Abstract

The complex design of the current network architecture, which has inevitably resulted in poor network resources management, has triggered researchers to propose a Software Defined Networking (SDN)-based network model to simplify the management of the limited bandwidth of a network. The key idea of the SDN-based model is to simplify network management by introducing a centralized control through which the dynamic update of forwarding rules, the simplification of network devices tasks, and flow abstractions can be realized. This proposed model utilizes the limited network bandwidth systematically by giving real-time traffic higher priority than non-real-time traffic to access limited resources. The experimental results showed that the proposed model helped ensure real-time traffic would be given greater priority to access the limited bandwidth, where the major portion of the limited bandwidth was allocated to the real-time traffic.
