【正文】 heme as so on. Nevertheless, a question es up that How to carry out smooth transition from IPv4 to IPv6 along with How to anize the IPv6 at the existing IPv4 work base, which these papers is going to cover over.First of all, in this paper, the author collects and analyzes the latest domesticoverseas information about the transition from IPv4 to IPv6，and studies IPv639。本文首先收集并分析國(guó)內(nèi)外關(guān)于 IPv6協(xié)議及 IPv6過(guò)渡問(wèn)題的最新資料，分析 IPv6新特性，描述了 IPv6協(xié)議的組件、特性等。這場(chǎng)變革的起因是 IPv4協(xié)議在面對(duì) Inter發(fā)展時(shí)出現(xiàn)越來(lái)越多的不足，人們?yōu)榻鉀Q這些不足提出用 IPv6協(xié)議取代 IPv4協(xié)議。IPv6具有諸如海量地址、組播、鄰居發(fā)現(xiàn)、自動(dòng)配置等許多新特性。并對(duì)目前常用的三種過(guò)渡技術(shù)雙協(xié)議棧、隧道和 IPv6/IPv4協(xié)議與地址轉(zhuǎn)換進(jìn)行分析比較。s new merits. Then the author depicts the modules, traits as well as routed and routing protocols based on , through the analysis in customary campus work structure, We are going to provide the work upgrade scheme, the method of deploying the coexisting policy connected IPv4/IPv6 in the process of transition, and the introduction about access connection of IPv6 tunnel techniques. With the IPv6 simulator’s experimental platform, in the purpose of revealing the IPv6 merits, based on DR existing IPv4 campus work, the implementations and authentications are evolved into the development of IPv6 layout and construction.Key words：IPv6；Tunnel Technology；Dual Stack目 錄論文總頁(yè)數(shù)： 34 頁(yè)1 引言
