校园网IPv4向IPv6 平滑过渡技术的研究与实现
摘要:经历了几十年的高速发展,已经成为人们生活中不可或缺的一部分。作为整个网络基石的IPv4也已经十分成熟。但是由于自身的限制,己经逐渐暴露了许多问题和缺点,于是IPv6被IETF设计出来用以替代IPV4。
整个网络从IPv4过渡到IPv6需要比较长的时间,两种网络将在今后长期共存。所以研究基于校园网的IPv4向IPv6的平滑过渡技术是十分必要且有前景的。
本论文将介绍IPv4的缺点,以及IPv6的诸多优点,分析几种常见过渡技术:双栈技术、隧道技术、NAT一PT协议转换。结合目前校园网的网络部署情况,将这些过渡技术合理的运用于其中,实现在当前以IPv4为主的网络中兼容IPv6网络。以期在今后将来很长的一段时间内做到在校园网内IPv4网络和IPv6网络互联互通。

The research and implementation of IPv4-based work smooth transition to IPv6
Abstract: has experienced several decades of rapid development, has e an indispensable part of life. As a cornerstone of the work of IPv4 has been very mature. However, due to its own limitations, has been gradually exposed the many problems and ings, therefore IETF IPv6 was designed to replace IPv4.
The work from IPv4 transition to IPv6 need for a long time, the works will coexist for a long time in the future. Therefore, based on the work of IPv4 the smooth transition to IPv6 technology is very promising and necessary.
This paper will introduce the ings of IPv4 and IPv6 the many advantages of technical analysis of mon transition: Dual-stack technology, the tunnel technology, NAT-PT protocol conversion. work with the work deployment, the transition of these technologies will be applied in a reasonable one, to achieve in the current IPv4-patible with work. With a view to the future in the future for a long period of time to the work in the IPv4 and work Interconnection.
Key words: wok, IPv6, smooth trasmition, tunnel technique, Dual stack,NAT-PT
