The research on network performance management system based on SDN technology

Network management plays an important role in improving the utilization ratio of network unit, positioning and troubleshooting fault, optimizing the network performance, ensuring network security and service quality. SDN (Software Defined Networking) has brought new chances and challenges for the development of network management technology. Thus, this paper has designed a network performance management system based on SDN. SNMP4J class library is used to develop network management system of the underlying application in this system. The data forwarding and controlling is separated through the SDN technology, which realizes functions: the collection and analysis of data, alarm and automatic control. Some test cases indicated that this system has many advantages, such as intelligence, high reliability and security, and so on.
