摘　　要：IPv4因其固有缺陷已不能满足网络服务和应用的不断普及和发展,由IPv4向IPv6过渡是互联网发展的必然趋势。本文针对IPv4和IPv6在互联网发展阶段必定长期共存的实际情况,分析了IPv4的局限性及其在地址资源、服务质量、安全性等方面的优势,介绍了双协议栈技术、隧道技术、网络地址转换/协议转换技术等三种过渡技术,讨论了各种技术的适用范围和工作机制。结合校园网网络实际环境,考虑到原有IPv4网络的复杂性、多样性、现实性和过渡过程必须平稳、安全、可靠的原则,利用过渡技术选择了一种适合校园网的IPv4到IPv6过渡解决方案,从而高效合理地利用了现有校园网资源、降低了成本投入。实际应用证明,达到了预期目标。Because of the inherent defects,IPv4 cannot satisfy the expansion and development of network services and applications. The transition from IPv4 to IPv6 is an inevitable trend in the development of the Internet. Aiming at the actual situation that IPv4 and IPv6 will coexist for a long term during the development,we analyze the limitations of IPv4 and the advantages of IPv6 in the address resources,service quality and security. This paper describes the technological requirements for running IPv6 in conjunction with IPv4（ including： protocols,dual stack,tunneling,etc.） and discusses the applicability of various technologies and mechanisms. In combination with the practical environment of campus network,considering the complexity,diversity and realism of existing IPv4 network,the transition process must be stable,safe and reliable. Using the transition technology,we choose a suitable solution to the transition from IPv4 to IPv6 transition of campus network,in order to use the existing resources efficiently and reasonably. The design reduces the costs. Practical application proves the desired goals.
