[Abstract]:With the rapid development of wireless network technology, WiFi has gradually become an important way for people to surf the Internet. However, with the increasing number of access users, the existing network bandwidth resources are becoming more and more difficult to meet the needs of users, how to effectively use the network bandwidth resources, better improve the quality of network service, It has become an important research direction of network quality service. When the traditional distributed network deploys the new services of the network, it is easy to lead to the complexity of the network structure and isomerization. Compared with the traditional distributed network, the software-defined network (SDN) has better network advantages. It adopts centralized control mode, data forwarding is separated from network control, and data forwarding is only responsible for the network data forwarding service. The service deployment will be handled by the control layer and the business logic will be programmed. This paper mainly studies the flow monitoring and bandwidth resource control management based on SDN technology, realizes the dynamic bandwidth resource allocation mechanism, effectively uses the network bandwidth resource, achieves the high efficiency bandwidth resource utilization. And according to different user needs, dynamic change of network services to meet the user's personalized service requirements, this paper mainly completed the following work: firstly, this paper analyzes the differences between traditional network architecture and software defined network architecture. This paper presents the advantages of software definition technology in wireless network, and designs and implements a wireless router based on OpenFlow function. It uses the advantage of SDN network to control and manage the network bandwidth resources. Secondly, aiming at the goal and demand of the whole system design, the design scheme of the whole control architecture and the function of each functional module are put forward. Finally, a miniaturized experimental network is set up to test the network traffic monitoring and bandwidth control using wireless router supporting OpenFlow function. The experimental results show that the monitoring feedback of network resources can be realized. Dynamically control the allocation of network resources and improve resource utilization.
