中文摘要：

随着IPv6的推广，很多用户终端已经开始具备IPv6机能。如何让普通用户，尤其是移动状态下的用户跨越IPV4网络享受IPV6服务，是当前研究的重要目的。文章提出一种基于隧道的IPV6孤岛子网管理机制，从理论角度简单分析优缺点，对提出的方法进行实验室环境和实际移动环境下的测试并给出简要分析。最后对现阶段的工作进行总结和展望。

英文摘要：

The popularization of IPv6 makes many user terminals have IPv6 function. It is important to research how to let regular users especially mobile users enjoy IPv6 service across the IPv4 network. This paper puts forward a kind of management mechanism based on IPv6 tunnel isolated subnet, analyzes theoretically the merits and demerits, tests the method in laboratorial and also real mobile environment. In the end it summarizes the work and gives a prospection for future research.
