中文摘要：

为了使IPv6客户端能够通过CDMA无线接入方式访问远程的IPv6服务器，介绍了已有的隧道技术并分析其不足，如不能适用于CDMA网络，提出并实现了一种基于NetFiher框架、Libnet和Libipq使得IPv6可以穿越CDMA网络的方法。实际应用表明，运用这种方法，IPv6主机可以有效地通过CDMA方式接入网络，并访问远程的IPv6服务器。

英文摘要：

In order to realize that IPv6 clients were able to visit remote IPv6 servers through CDMA, the existing tunnel methods were overviewed. After discussing the limitation of these existing methods which were not suitable for CDMA network, and then based on NetFilter framework, Libnet as well as Libipq one method that made IPv6 protocol go through CDMA net- work was put forward and implemented. Applications show that through this method those isolated IPv6 areas can be efficiently connected by CDMA network.
