1、XXXXX本科生毕业论文IVIPv6与IPv4互联技术的探讨摘要:随着Internet的发展尤其是规模爆炸式的增长,IPv4固有的一些缺陷也逐渐暴露出来,包括地址枯竭、路由瓶颈、安全和服务质量难以保障等问题。在此背景下,新的网络层协议IPv6它克服了IPv4的诸多不足而显示出许多新的特性。但IPv6网络完全替代IPv4网络并非是一朝一夕的事情,IPv4现已具备相当完善的网络环境与设备生产,各种网络协议和通信协议都是以IPv4为技术基础,在未来几十年内网络世界将会出现IPv6与IPv4共存互联的局面,针对这种状况IETF
2、也提出了很多的过渡互联技术,主要包括双栈、隧道和协议转换三种技术,但却没有一种互联技术是通用的,都有各自的局限性,现在更多的采用几种过渡互联技术混合使用,实现以最小的代价达到平稳过渡。本论文分析和论述了IPv6提出的背景和必要性,同时深入讨论了IPv6协议显示出的新特性及在过渡期间存在的问题,着重探讨了双栈、隧道和协议转换三种过渡互联技术,以及每种过渡互联技术采用的方法与机制,并对其进行了模拟与分析,最后基于xxx校园网给出了自己的过渡设计方案关键词:IPv4;IPv6;互联技术;过渡策略;校园网XXXXX本科生毕业论
