.ipv4/ipv6 Internet Key Technology Research And Application Development

With the IT developing rapidly, the computer using generally, and each kind of the equipment connecting, the IP address that the IPv4 protocol provides has already faced the depletion. According to nowadays' network developing speed, The IP address will be exhausted in future 10 years. Although People found out some methods to alleviate this severe question, it can not be solved fundamentally. That causes to the new generation protocol IPv6 development becoming impatient. whether IPv4 to IPv6 transition can obtain this success or not directly influences IPv6 Internet's development. But there is a lot of difficulties in the research of transition from IPv4 to IPv6. The using of different plan in different situation have the different effect. We must not only consider the feasibility of the IPv4 to IPv6 transition, but also give dual attention to reduce each aspect's influence produced by some solutions as possible in the transition.This paper first explains the inevitability of long-term co-existences and the necessity of interconnection transition in the IPv4 and the IPv6 protocols according to the distributed situations and the characteristic of the two kinds of protocol in present computer network.. The key is to make a concrete analysis on each kind of existing transition technology, to propose new thought and idea, then to proves its feasibility through a series of experiments. The prime task of this paper is:Carry on the multi analysis to addresses of two kinds of protocols, and confirm their characteristic of pass ability.Set up the experiment environment, and confirm the feasibility of the new seal strategy proposed in paper.Make a deep study of network programming on Socket connection, realize the protocol irrelevant Web server in the double stack node.Develop network address disposal procedure based on the TRT/ALG technology, realize the pure IPv4 host and the pure IPv6 host information intercommunication.In this article, experiments are realized based on Windows XP operating system, VC++6.0 integrated development environment, and 3 resurgence ZXR10 GAR router.
