Research Of IPV6 Transition Technology And Deployment Scheme For CMNET Metropolitan Area Network

With the rapid development of today's network technology,the number of network users continues to expand,and the demand for IP address is also growing geometrically;in this context,IPv4 technology has been difficult to meet the rapid growth of network address business needs,and it has become the bottleneck of the rapid development of Internet technology.With the increasing demand of Internet technology,IPv6 technology is born naturally.As an upgraded version of IPv4 technology,IPv6 has its unique technical advantages in the sky.After the specific technology selection,IPv6 can achieve a smooth transition with IPv4 technology.In this paper,the main research is in the man environment,how to choose the technology and deployment scheme of IPv6 transition for operators,IPv6 technology will become the basic direction and core of network development and construction in the future because it can provide more address space and has better scalability.However,because a large number of devices and applications of the previous network are based on IPv4 technology,it is difficult to replace all of them to IPv6 protocol in a short time,so there is a transition period between IPv4 technology and IPv6 technology,and the choice of the transition period technology is the key to the research.The choice of the technology that can be realized can not only take into account the transition of the two network technologies,but also have the ability to solve the problem of IP address shortage Force to achieve a high standard of network balance.Based on the in-depth study and analysis of the three transition technologies,the network environment applicable to the three protocols,the existing network structure characteristics and project investment cost of Tonghua mobile man,this paper decides to adopt the dual stack technology in this scheme,including the deployment mode,user traceability mode and port allocation,etc.The paper focuses on the technical details of the deployment scheme,which are detailed in the following This paper discusses in detail the principle and model of dual stack technology deployment,and further studies the deployment of related supporting software and hardware.Based on the implementation of network deployment and theoretical research and analysis,the IPv6 protocol technology was tested under the experimental condition of network performance.All the results of the test met the requirements of network side network structure,and achieved the expected effect.The transition deployment of the whole man from IPv4 to IPv6 was successful.In the later stage,it can comprehensively promote the Internet construction goal of IPv6 operation.
