The Design and Implementation of NAT System based on NDIS

Abstract

近年来基于IPv4协议的因特网得到了蓬勃发展,无论是网络覆盖的范围与网络容量,还是网民数量与业务类型都在飞速增长。IPv4下其可用的IP地址越来越少,一些解决地址危机的办法开始得以广泛使用,其中中短期解决方案——网络地址转换技术是目前最常用的解决地址短缺的有效的方法。 论文首先分析了计算机网络参考模型TCP/IP,并对网络地址转换的原理和工作过程进行了研究,提出了在链路层之上基于NDIS(中间层驱动)模块化插件式的的解决方案;软件由两部分组成:内核部分工作在操作系统内核层(0层),完成网络数据的截获、分析、跟踪、过滤、转换等功能,控制部分工作在应用层,负责与内核的通信与控制。内核部分可以对所...Recent years, Internet based on IPv4 protocol has been flourishing, whether the scope of the network coverage and network capacity or the number of Internet users and business types is in the rapid growth. So the amount of available IP address is less and less under IPv4.Some of solutions to IP address crisis begin to be widely used. NAT technology is a short term solution, and it is the most comm...学位:工程硕士院系专业:信息科学与技术学院计算机科学系_计算机技术学号:X200922103
