Abstract

Along with the rapid development of the human society, computer technology and communication technology has been an unprecedented increase. Computer network already in production, and occupy an increasingly important position in life, has gone deep into the various areas of human life. Played a very large role in the computer network technology for the rapid development of society. Information technology, running the most successful, the most mature is the Internet network. Internet network development from birth to now, completely change the existing state of society, to be known as one of the representative of the new technology of the 21st century. Internet network from the date of birth, IPv4 protocol as the cornerstone of the network and soul, for the development of the Internet network have made indelible contributions. Despite the current Internet network running IPv4 protocol is very mature, constitute the basis of the Internet, but the rapid development of the network and the characteristics of the IPv4 protocol restrictions IPv4 protocol exposes more and more difficult to overcome the shortcomings, has been difficult to adapt to the future the development of the Internet network. In order to solve the difficulties faced by the Internet network, change inherent in the network based on the IPv4 protocol, the IETF developed by the IPv6 protocol. As the next-generation network protocol IPv6 protocol to address the many shortcomings of IPv4 protocol optimized for other important functions. Among the large IP address space, optimize network speed and high security features. Although there are many advantages of IPv6 protocol, Internet network to IPv6 protocol network development is imperative. Network transition from IPv4 protocol to IPv6 protocol is a long-term process and can not be done overnight, and many other standard and experimental IPv6 network is also underway. So, in the transition process, develop a transition strategy, the network is particularly important to ensure how smooth the transition. The paper describes the characteristics of the two protocols IPv4, IPv6, and compared. Elaborated the importance, necessity, and the transition of IPv4 network to IPv6 network transition strategy selection. The paper describes three transition method, dual-stack, tunneling and protocol conversion technology. IPv6 network relatively rapid development, the CERNET2 network connected to a number of campus network for pure IPv6 protocol network, network backbone network of the next-generation IPv6 protocol. Campus network are connected to the the CERNET2 network, sharing of educational resources in the national university. The special nature of the college decided to become a platform for network experiments. Chaoyang Teachers College campus network is a typical medium-sized networks, the paper Chaoyang Teachers College campus network to rely on detailed several major transition strategy, I believe, a college campus network to the successful transition of IPv6 network the comprehensive upgrade can build the entire Internet network play a very good reference.
