中文摘要：

针对无线局域网（WLAN）设备不能直接支持IPv6协议的问题,以清华大学无线校园网为基础,描述IPv6在WLAN中的2种典型部署方式：无状态IPv4/IPv6双栈接入和有状态纯IPv6接入,探索IPv6协议在WLAN中的最佳实现方式。运行结果表明,2种部署方式均可为WLAN用户提供有效的IPv6服务。

英文摘要：

As IPv6 protocol can not be deployed directly in most Wireless Local Area Network（WLAN）,based on the campus WLAN of Tsinghua University,this paper describes two development ways： stateful IPv4/IPv6 double stack access and stateless IPv6 access.Best implementation way of IPv6 in WLAN is studied.Operation result shows that these two ways can both provide good service to WLAN clients.Experience is accumulated for IPv6 promotion and WLAN clients accessing next-generation Internet.
