太原理工大学硕 士 学 位 论 文 摘 要 网络缓存（Web Caching）把经常访问的网络对象在访问开 销较少的网络节点上存一个副本，当用户再次访问这些对象时， 可以直接从这个开销较少的网络节点上得到满足。从而在有限 的带宽内，达到缩短用户等待时间、提高网络性能和网络可扩 展性的目的，对于提高Internet 访问效率具有重要意义。-Taiyuan University of Technology master"s degree thesis Abstract network cache (Web Caching) frequent visits to the network to visit the object of the less expensive network nodes onto a copy, when users visit these objects, directly from the overhead less network nodes to be met. Thus the limited bandwidth, which can shorten the waiting time for customers, improve network performance and network scalability for the purpose of improving the efficiency of Internet access is of vital significance.

本文首先分析Linux2.6.6内核新特性的基础,探讨对Linux进行实时化和嵌入式化,即通过配置内核,裁减shell和嵌入式C库对系统定制,使整个系统能够存放到容量较小的FLASH中。然后简单介绍了防火墙的概念,深入地分析了Linux2.6.6版新型内核防火墙netfilter框架的工作机制及其实现的方式。-In this paper, the kernel Linux2.6.6 the basis of new features to explore on the Linux and embedded real-time, that is by configuring the kernel, the reduction of shell and embedded C library on the system customization, so that the entire system to the capacity to store more FLASH in the small. And then briefly introduced the concept of a firewall, in-depth analysis of the new kernel version Linux2.6.6 firewall netfilter framework of the working mechanism and its implementation approach.
