Design Of The QoS Management System Based On The OpenFlow For The IPv6 Network

With the continued development of network technology, many previously unimaginable applications has emerged, including VoIP, video conferencing and many other business demand the high network quality of service. These operations can be said with the emergence of the user's actual needs, but they also exposed the emergence of many problems in addition to the current network, thus contributing to the development of the network. These include defects in the IPv4 protocol, network performance is inadequate and so on. In order to alleviate people's needs and the current network can not meet the needs, IETF proposed a variety of improvement programs, including the IPv6 protocol, QoS management and so on. These techniques have already been carried out, but in these applications, also exposed some problems. One of the most prominent is that in the actual network QoS management, as a result of the huge and complex network, routing table would be too big; the QoS management also would bring the router a big work load, so the router will make the network work can't work. Accordingly, the study of QoS in IPv6 is still has great significance.This paper describes the IPv6 technology, QoS technology and OpenFlow technology. Analysis of the main methods and techniques in the QoS management and is proposed to be implemented in IPv6. Finally, with the actual network management problems encountered about the work load, OpenFlow technology will be used in the management system to design a new type of management system. In addition to implemented the traditional QoS management features in the IPv6 network, also to reduce the workload in the router of the management system. Avoid excessive workload significantly improved the network performance. At last, we make a few experiments to test the performance of the system and proved the success of the system. In the end of this article, we summarizes the results of research and further research directions.
