摘　　要：从IPv4(Internet Protocol Version4)到IPv6的过渡是一个复杂的过程，针对IPv4到IPv6的转换问题已有很多解决方案。文中详尽讨论了在IPv6部署初期所采用的关键技术——IPv6 over IPv4隧道技术的原理，并逐一对比分析了目前主流的5种IPv6 over IPv4隧道技术（手工配置隧道、IPv4 GRE(generic routing encpsulation)隧道、隧道代理、自动配置隧道、6to4隧道）的机理、实现方式以及应用场合。The transition from IPv4 to IPv6 is a long and complex period; there are lots of transition strategies from IPv4 to IPv6. In this paper, a key IPv6 deployment strategy in the early stages in deployment of IPv6 is discussed, and the implementation mechanism, deploying method and key primary use of each 5 main implementation technologies of IPv6 over IPv4 tunnels such as IPv6 manually configured tunnel, IPv6 over IPv4 GRE tunnel, tunnel broker, automatic IPv4-compatible tunnel and automatic 6to4 tunnel are analyzed in detail one by one.
