发布时间：2019-03-19 18:04
【摘要】：随着互联网规模的急剧增长,IPv4地址资源已经枯竭。IPv6能够解决IPv4地址资源不足的问题,同时还具有更高的安全性、移动更方便、即插即用性、多样化的服务质量等多方面的优势,IPv6取代IPv4已成必然。随着CERNET2主干网的正式开通,以及国家相关部委科技计划的不断推出和政策支持,全国众多高校紧紧抓住发展契机,积极实施校园网的升级改造,成为中国下一代互联网建设的先锋。因此研究校园网的过渡技术、校园网络的应用改造有重要的现实意义。本文首先介绍了当前国内外研究IPv6协议的现状,研究了IPv6协议的新特点,网络地址及数据包与IPv4相比的优势,安全性与服务质量的加强,邻居发现协议及路由协议的实现等。分析了当前较为成熟的三种基本过渡技术:双协议栈技术、协议转换技术和隧道技术。以我校医学部校区的网络拓扑结构为基础,分析了校园网建设IPv6网络的需求,针对医学部校区网络结构,设计了校园网向IPv6过渡的接入改造方案。并在该方案基础上,通过一系列实验,对建设IPv6校园网过程中涉及到的主要过渡技术和策略作了可行性验证。
[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.
