IPv6与IPv4的互连技术探讨与实现 摘 要：随着现代科技和生产需求的不断发展与增加，最初的IPv4协议已不能满足现代社会的需求，因此，一种新的协议IPv6诞生了。IPv6被作为下一代互联网络协议核心标准之一，它将取代IPv4协议，但取代IPv4协议还需经过一个漫长的时期，因此IPv6与IPv4间的互连是保持Internet长期可持续发展的重要问题且对相关的研究和相关软件的开发具有理论价值和实际意义。 本文分析和论述了IPv6协议提出的背景意义和紧迫性，深入研究了IPv6协议的基本原理，探讨了多种IPv6与IPv4互连的技术——双协议栈、隧道技术及NAT-PT技术。本文还模拟实验了在不同网络环境下IPv6的网络互连，实现了IPv6网络内的通信，并对其结果进行了详尽的分析。最后，对论文做了总结，并提出了对IPv6与IPv4网络互连技术的展望。 关键词：IPv6协议；IPv4协议；互联技术 Discussion and Implementation of IPv6 and IPv4 Interconnection Technology Abstract：With the continuous development of modern science and technology and the production requirements and increase, the original IPv4 already cannot satisfy the demand of modern society, as a result, a new protocol IPv6 was born. IPv6 is one of the core standards as the next generation Internet protocol, it will replace IPv4, but replace IPv4 only after a long period, thus between IPv6 and IPv4 interconnection is to keep the Internet and long-term sustainable development of the important problems of relevant research and related software development has theoretical value and practical significance. This paper analysis and discusses the significance and urgency of IPv6 protocol proposed background, further study of the basic principle of IPv6 and IPv4 and IPv6, discusses a variety of IPv6 and IPv4 interconnection technology, dual stack, tunnel technology and NAT - PT. This paper also simulated experiments in different IPv6 network interconnection under the network environment, implements the IPv6 network communication, and the results are all analyzed. Finally, the paper made a detailed summary, and put forward the prospect of IPv6 and IPv4 network interconnection technology.
