【摘要】：随着互联网以及计算机技术的飞速发展,基于IPv4协议的网络面临的众多问题正显现出来,其中地址空间不足和网络安全性问题最为严重。为此,国际上提出了下一代互联网协议IPv6。而由IPv4向IPv6转化不可能在短时间内完成,因此IPv6和IPv4将在很长一段时间内处于共存,如何使这两种不同的协议共存成为目前亟待解决的问题。 本文围绕某研究中心中国下一代互联网(CNGI)的IPv6网络过渡建设,进行前期的现状分析、需求分析,并提出切实可行的基于双协议栈过渡技术的IPv6网络过渡方案,并进行网络过渡整体设计,同时,对IPv6协议的相关特性进行研究,在研究的基础上对IPv6协议和IPv4协议进行充分的对比,指出IPv6协议中提出的许多新特性和优点。并探讨IPv4网络向IPv6网络过渡的技术,分别对过渡中使用的双协议栈技术、隧道技术和网络地址转换／协议转换技术三种过渡技术进行较为深入的研究和分析,比较它们各自的优缺点、性能及适用环境,并对三种过渡技术下的网络环境进行模拟搭建和技术实现,得出不同的网络环境需要选择不同的过渡技术的结论。重点展开对双协议栈的研究,包括工作原理、路由算法等内容。 在理论分析和模拟环境测试的基础上,对基于双协议栈技术的IPv6网络设计进行验证,完成研究中心CNGI的IPv6网络过渡建设实施工作,进行实际测试验证,结果证明了本次设计的正确性和有效性。通过此次网络过渡实施,完成了基于双协议栈技术的IPv6网络接入,实现了预期的设计目标。
[Abstract]:With the rapid development of the Internet and computer technology, many problems facing the network based on IPv4 protocol are emerging, among which the insufficient address space and the network security are the most serious problems. Therefore, the next generation Internet protocol IPv6 is proposed internationally. However, the transformation from IPv4 to IPv6 can not be completed in a short time, so IPv6 and IPv4 will coexist for a long time. How to make these two different protocols coexist becomes an urgent problem. This paper focuses on the construction of the IPv6 network transition in a research center China next Generation Internet (CNGI), analyzes the current situation, needs and proposes a feasible IPv6 network transition scheme based on the dual-protocol stack transition technology. At the same time, the related characteristics of IPv6 protocol are studied. On the basis of the research, the comparison between IPv6 protocol and IPv4 protocol is made, and many new features and advantages of IPv6 protocol are pointed out. The technology of transition from IPv4 network to IPv6 network is discussed. Three transition technologies, namely, dual-protocol stack technology, tunnel technology and network address translation / protocol translation technology, are studied and analyzed. By comparing their advantages and disadvantages, performance and applicable environment, and simulating the network environment under the three transition technologies, the conclusion is drawn that different network environments need to choose different transition technologies. This paper focuses on the research of dual protocol stack, including working principle, routing algorithm and so on. On the basis of theoretical analysis and simulation environment testing, the design of IPv6 network based on dual-protocol stack technology is verified, and the transition construction of IPv6 network of CNGI research center is completed, and the actual test verification is carried out. The results show that the design is correct and effective. Through the implementation of this network transition, the IPv6 network access based on dual protocol stack technology is completed, and the expected design goal is achieved.
