【摘要】 自20 世纪70 年代IPv4 诞生以来,随着Internet 的急速发展,IP 地址即将耗尽及路由表急速膨胀的问题日益突出。为了解决Internet 目前所面临的巨大挑战,IETF 制定并完善了新一代IP 协议,即IPV6。IPv6 协议吸取了IPv4 的优点并力争弥补其不足之处,如解决了地址耗尽问题、具有内置的安全性和移动性等。我们现在关注的己不再是应不应该由IPv4 过渡到IPv6,而是如何渐进地、无伤害地由基于IPv4 的网络过渡到基于IPv6 的网络,同时尽可能减少过渡的成本。IPv6 协议的新特性为下一代互联网的应用和发展提供了更加广阔的前景和完善的支持。本文主要做了以下几方面的工作: (1) 研究了IPv6 新协议,分析比较了IPv4 和IPv6 两种协议的异同点,通过剖析IPv6 的特点及其技术规范,重点在双协议栈技术、隧道技术和NAT-PT 技术方面进行了相关实验研究。(2) 探讨了IPv6 的地址管理策略,研究了IPv6 地址配置中最重要的邻居发现协议和IPv6 的无状态自动配置以及全状态自动配置的过程。(3) 分析DHCPv4 和DHCPv6 的差异,利用工作原理图、状态变迁图,研究了DHCPV6 客户机和服务器的状态变迁和信息交换过程,并初步实现DHCPv6 的功能。更多还原

【Abstract】 Since IPv4 was born in the seventies of the 20th century, with the development rapidly of Internet, the question that IP address will exhausted and the route form expand rapidly is outstanding day by day. In order to solve the enormous challenges of Internet at present, IETF makes and perfects new generation protocol, namely IPv6. IPv6 protocol draws advantage of IPv4 and remedy it weakness, such as solving address exhausted problem, having built-in security and mobile .The problem that we pay close attention to isn’t that it is should or not to be transferred from IPv4 to IPv6, but how to be advance gradually and injury transferred from IPv4 to IPv6, reduce the cost of the transition as much as possible at the same time . The new characteristic of IPv6 protocol has offered the support of wider prospect and perfection for application and development of next generation Internet. This text has done the work of the following aspects mainly: 1. Research this new protocol of IPv6, analyzed and compared the similarities and differences between IPv4 and IPv6, through analyzing the characteristic and technical specification of IPv6, studying and comparing the merit and disadvantage of several kinds of transition technology. 2. Discussed the tactics of IPv6 address management, analyzed the most important neighbor discovery protocol and stateless autoconfiguration and stateful autoconfigruration in IPv6. 3. This text still deeper analysed difference between DHCPv4 and DHCPv6, utilize the operation principle and state changes picture, has research the state changes of DHCPV6 client and server and information exchange course more completely, and tentatively realize the function of DHCPv6.更多还原
