面向Windows的CLAT及其接入系统的设计与实现

Design and Implementation of Windows CLAT Access Systems

因为IPv4地址池的耗尽,对很多网络来说给终端用户分配地址是一件很困难的事情,所以IPv6开始实际部署与应用。为了实现IPv4与IPv6的过渡,本文提出了一种基于双重翻译方式的IPv4与IPv6的过渡技术。首先捕获本地即将发送的数据包,然后使用数据包转换算法对已经捕获的数据包进行翻译。进而将翻译出的结果即IPv6数据包发送给纯IPv6的网络环境。通过接收数据包的服务器对IPv6数据包的进一步转换,实现与目标IPv4主机的通信。

Because IPv4 address pool is exhausted,it is very difficult to assign addresses to end users and many other networks.So we actually start to deployment and application IPv6 protocol.In order to achieve the transition of IPv4 and IPv6,in this paper,the IPv4 and IPv6 transition technologies bases on double translation approach.First, capture the local packets which are to be sent out.Then the data packet conversion algorithm is used to translate the captured packets.Consequently,the translated result which is the IPv6 packet will be sent to pure IPv6 network envi-ronment.The server receives IPv6 packets and then translates these IPv6 packets to IPv4 packets.Enabling communicate with the destination IPv4 host.
