摘　　要：本文简要介绍了下一代互联网的发展,研究了从IPv4到IPv6的过渡方式,包括双协议栈技术、隧道技术以及网络地址转换/协议转换技术;重点解决了以下几个问题:①通过在校园网出口增加双栈交换路由设备并使用双栈技术,实现了一条线路同时连接CERNET与CERNET2网络;②在校内核心交换机上建立ISATAP隧道入口,使校内用户可以通过隧道方式访问CERNET2资源;③在UNIX系统上使用B ind 9搭建了基于IPv6协议的域名系统,能同时为IPv4和IPv6网络解析校内IPv6域名。目前,重庆师范大学IPv6网络的基础结构和基础应用服务已经构建完毕,为以后从IPv4网络向IPv6网络过渡做准备,也为没有构建IPv6校园网的学校提供参考。According to the analysis of China Internet Network Information Center, the global IPv4 address would be exhausted and the inborn limitation like network single breakdown, bottle-neck of capability, and security problem of IPv4 are becoming more and more serious, so the introduction of IPv6 into internet is imminent. Firstly, the thesis recalls the development history of Internet briefly and then analyzes the transitional way from IPv4 to IPv6. In order to set up the next generation campus network, focuses on the way to solve the problems of how to connect CERNET2, the setup of automatic channel, the way to configure IPv6 domain name system and so on, so as to lay the foundation to the transition from IPv4 network to IPv6 network in times to come with a hope to provide a model for other schools without network. At present, the basic structure and application services of Chongqing Normal University have been completed and the users within the school can visit CERNET2 and foreign IPv6 resources freely. Based on this achievement, we will work on the research and application of related technologies so as to strengthen the information construction of the school.
