摘要
IPv6融合和涵盖了多种先进的网络技术并具有良好的扩展性,已经成为下一代互联网中的主流网络层协议。然而IPv4向IPv6过渡将是一个长期的增量部署过程,此过程不得不考虑如何实现IPv4到IPv6的平滑过渡。文中首先分析比较了IPv4与IPv6地址体系结构和数据报格式,接着介绍了双栈技术、隧道技术、转换技术三类主要过渡技术的实现原理,并重点研究比较了各种隧道技术和转换技术的主要适用场景及优缺点,同时对它们的安全性进行了分析。最后进行了总结并讨论了在在向IPv6网络演进过程中还存在的问题。
IPv6 comprises multiple advanced network technologies and outdoes the current IPv4 with significant advantages.However the IPv4 to IPv6 transition will be a long-term incremental deployment process,this process must consider how to real ize the smooth transition of IPv4 to IPv6.In this paper,we first analyze the address architecture and datagram format of the IPv4 and IPv6,and then introduce the realization principles of the three main transition mechanisms,the dual-stack,tunneling and conversion technologies,and focus on the implementation of main application scenes,the advantages and disadvantages of the tunneling and conversion technology,meanwhile their safety were analyzed.Finally the discusssion and problemare summarized in the IPv6 to the network evolution process.
