Under The Agreement Of IPv6 Network Management Systems Analysis And Design

Both that of in company with internet at very fast speed develop and network upgrade cry for,IPv4 deficiency increasingly show,as address space insufficiency, mobility difference, security difference and deploy intricacy wait aspect. Wherefore IETF set know clearly IPv6 standard in settlement of these issue.The main contents are as follows: First of all, to introduce an analysis of the development of IPV6. Europe and the United States, Japan and Korea attaches great importance to the development of IPV6, the development of specific planning and deployment. , Japan, the IPv6 technology as the establishment of the Government's basic policies, the existing network to promote the transition to IPv6 network as a "super-high-speed network-building and competition policy," the specific goal; Korea has developed four stages of development in preparation for the current IPV4 The gradual transition to a pure network IPV6 networks, and in the policy, legal, funding and so on to give strong support; Europe in the Internet's advantages in mobile communications, and its corresponding strategy is the "first move after the fixed" in the hope of rivals and the United States, focus on 3G mobile communications equipment, and the most powerful tools that support IPV6; on the other hand, IPV6 meeting of the widely held, IPv6 Forum in France, the United States, Spain , Japan, Canada convened a Global IPv6 Summit, the popularity of the development of IPV6; the first in China to popularize campus network, and then extend to other industries line. So far, there are more than 100 colleges and universities access to the IPv6 network, through a state appraisal.The second chapter focuses on the transition phase of the strategy, technology, and the campus network during the transitional period of Network and DNS server during the transition phase of the design. At present, the campus network use IPv6 protocol stack of two-way, the campus intranet to take IPv4/IPv6 co-existence agreement manner, and the campus of communication between the campus and basically take the pure IPv6 agreement. Chapter III of the Theory of IPv6 protocol under the QOS system. With the Internet and the rapid development of a variety of businesses, especially video, voice, and so on the rapid growth of multimedia services, IP networks from the previous single data network into a multi-service integrated digital network. At this point, the traditional IP network does not guarantee the quality of service vulnerability has been displayed. To this end, the industry put forward the concept of IP QoS, that is, in the hope that the IP network can provide businesses with different corresponding QoS guarantee. Into the era of IPv6 protocol, the network QOS, in particular by the majority of users of common concern. A brief article in today's IP QoS technology in the main program and their corresponding shortcomings, and then put forward in the field of IP QoS need to focus on some issues, in particular the attention of the highest degree of safety.In chapter four, it's the whole design of network management based SNMP in IPV6. The system is designed in two perspectives. One is called horizontal division. The other is vertical division. The horizontal division is configuration management, performance management, fault management, accounting management, secure management. The vertical division is collection model, analyze model, view model. Then, requirements analysis is given. I gave the detail design of collection model because it is the fundamental model of other models.Chapter five is the implementation of collection model. I use the Java development language. There are two development kits for use,SNMP4J and JFreeChart. Some SNMP operations are packaged in SNMP4J and JFreeChart is quite helpful to make chart. The collection data can be viewed in the screen through methods provided by JFreeChart, which can be useful for analyzing. In collection model, four equipments can be collected and monitored. They are management console, cisco7609 router, DNS6 web server, HuaWeiNE80 router(IPV6 only router). IPV6 MIB instance can be got in DNS6 web server. Some instance can not be got, but we can use the methods mentioned in chapter three. HuaWeiNE80 router is the convergence router of Jilin province of IPV6 communication. In this chapter, data collection, statistical graphic, data analysis of HuaWeiNE80 router are implemented. Because of inadequate supports of IPV6 MIB in this router, we get the interface MIB instance instead of IPV6 MIB instance. The communication through this router is all IPV6 communication, so this way can also statistic IPV6 flow in and out interface of the router. It's a good way. I collect the IfInOctets(MIB instance of interface group .It means the flow into router)and IfOutOctets every ten minutes and then calculate the net flows during that time. That can be useful for data analysis.In the end, I conclude the whole paper and imagine next job.
