文档介绍：摘要
随着互联网技术的快速发展,基石的TCP/IP协议族正在进行着一场前所未有的变革。发展时显现出越来越多的不足,人们为解决这些不足提出用IPv6协议取代IPv4协议的方案。IPv6作为下一代互联网的核心协议,具有诸如海量地址、组播、邻居发现、自动配置、服务质量、可移动等许多新特性,现行的IPv4向IPv6过渡势在必行。然而,怎样实现IPv4向IPv6的平滑过渡和在现有的IPV4网络上部署IPv6网络仍然是目前混合组网的主要研究方向。
本文首先收集了国内外在研究IPv6协议和IPv6过渡技术的最新资料,并分析了IPv6新特性,描述了IPv6协议的组件及特性等,对目前比较成熟的三种过渡技术,双协议栈、隧道和IPv6/IPv4协议与地址转换进行了全面的分析和比较。然后,对现有的IPv4校园网络结构进行了分析,提出了几种适合现有IPv4校园网络平滑升级到IPv6校园网络的规划方案,并在网络设备的选择上进行了详细的介绍。论文中的实验基于Dynamips网络仿真模拟工具,基于实际校园网的情况并充分体现IPv6的特性的基础上,结合IPv4校园网现状,构造了IPv6实验平台,并对IPv6校园网方案进行验证。

ABSTRACT
As the technology has developed rapidly, to cornerstones of ip the tcp protocol is a game of unprecedented changes. this change is the cause of the agreement on the ipv4 development of an increasing number of people to solve the deficiencies in the agreement replaced by ipv6 ipv4 agreement. Ipv6 as the core of the next generation protocols, such as will an address, the group, found on his neighbour, automatic configuration, quality service, mobile and many new features, ipv4 to ipv6 the transition it is imperative. however, ipv4 to ipv6 how to achieve a smooth transition and in the existing ipv4 work deployment work and is still present a major study.
The first collection and study ipv6 agreement and the transition of the latest information technology to ipv6, and analyzed ipv6 the new features, ipv6 agreement and features, for there is three types of technology, the protocol stack transition, ipv4 to ipv6 tunnel and agreements address translation for a full analysis parison. Then, ipv4 to the existing campus was analysed and made some of the existing ipv4 to work is upgrade to the planning scheme, work equipment chosen on the details. work based on paper experiments based on actual simulation tools, in case of campus and fully reflect the characteristics of IPv6 basis, combining IPv4 campus, constructed IPv6 experimental platform, test IPv6 campus of the experiment and plan.
