【摘要】：隨著互聯(lián)網(wǎng)規(guī)模的急劇增長,IPv4地址資源已經(jīng)枯竭。IPv6能夠解決IPv4地址資源不足的問題,同時還具有更高的安全性、移動更方便、即插即用性、多樣化的服務質(zhì)量等多方面的優(yōu)勢,IPv6取代IPv4已成必然。隨著CERNET2主干網(wǎng)的正式開通,以及國家相關(guān)部委科技計劃的不斷推出和政策支持,全國眾多高校緊緊抓住發(fā)展契機,積極實施校園網(wǎng)的升級改造,成為中國下一代互聯(lián)網(wǎng)建設(shè)的先鋒。因此研究校園網(wǎng)的過渡技術(shù)、校園網(wǎng)絡的應用改造有重要的現(xiàn)實意義。本文首先介紹了當前國內(nèi)外研究IPv6協(xié)議的現(xiàn)狀,研究了IPv6協(xié)議的新特點,網(wǎng)絡地址及數(shù)據(jù)包與IPv4相比的優(yōu)勢,安全性與服務質(zhì)量的加強,鄰居發(fā)現(xiàn)協(xié)議及路由協(xié)議的實現(xiàn)等。分析了當前較為成熟的三種基本過渡技術(shù):雙協(xié)議棧技術(shù)、協(xié)議轉(zhuǎn)換技術(shù)和隧道技術(shù)。以我校醫(yī)學部校區(qū)的網(wǎng)絡拓撲結(jié)構(gòu)為基礎(chǔ),分析了校園網(wǎng)建設(shè)IPv6網(wǎng)絡的需求,針對醫(yī)學部校區(qū)網(wǎng)絡結(jié)構(gòu),設(shè)計了校園網(wǎng)向IPv6過渡的接入改造方案。并在該方案基礎(chǔ)上,通過一系列實驗,對建設(shè)IPv6校園網(wǎng)過程中涉及到的主要過渡技術(shù)和策略作了可行性驗證。
[Abstract]:With the rapid growth of the size of the Internet, IPv4 address resources have been exhausted. IPv6 can solve the problem of insufficient IPv4 address resources, at the same time it has higher security, more convenient mobility, plug and play, Diversified quality of service and other advantages, IPv6 instead of IPv4 has become inevitable. With the official opening of the CERNET2 backbone network, as well as the continuous introduction and policy support of the science and technology plans of the relevant national ministries and ministries, many universities throughout the country seize the opportunity of development and actively implement the upgrading and transformation of the campus network. To become China's next generation of Internet construction pioneer. Therefore, it is of great practical significance to study the transition technology of campus network and the application and transformation of campus network. This paper first introduces the current situation of IPv6 protocol research at home and abroad, and studies the new characteristics of IPv6 protocol, the advantages of network address and packet compared with IPv4, the enhancement of security and quality of service, the implementation of neighbor discovery protocol and routing protocol, and so on. This paper analyzes three mature basic transition technologies: dual stack technology, protocol conversion technology and tunneling technology. Based on the network topology structure of medical school campus of our university, this paper analyzes the requirement of constructing IPv6 network in campus network, and designs an access transformation scheme from campus network to IPv6 according to the network structure of medical school campus. On the basis of this scheme, a series of experiments are carried out to verify the feasibility of the main transition technologies and strategies involved in the construction of IPv6 campus network.
