摘　　要：当前,由于互联网规模急剧增长,IPv4地址枯竭问题日益严重,IPv4向IPv6过渡的问题十分紧迫。然而IPv6与IPv4不兼容,在IPv4向IPv6过渡时期,IPv4与IPv6网络共存,带来了IPv4-IPv6互联与穿越等基本需求。对此,目前国际上提出了许多过渡方案。这些技术方案针对不同的网络场景、用户的需求和过渡阶段提出,其技术思想也不尽相同。本文根据IPv6过渡技术特点以及国际研究进展,分类介绍了现阶段比较成熟的过渡关键技术,希望能为读者提供一些借鉴价值。Nowadays, with the rapid development of the Internet, the problem of IPv4 addresses depletion is getting increasingly serious, and the transition from IPv4 to IPv6 becomes very urgent.However, IPv4 and IPv6 network will both exist duringthe transition period, while the two are not compatible in nature. Therefore it brings primary demands of IPv4-IPv6 connect and across. For the demendsof IPv6 transition, there are many transition technologies have been put forward. These technologies are proposed to meet with various requirements under different scenarios during transition phases, which lead the diversity of major features. This paper introduces some key transition technologies which are relativelymature and stable according to the IPv6 transition trend worldwide.
