基于ARM的防火墙系统设计与实现

摘要

Based on ARM hardware architecture, we build the embedded development platform through the porting of Linux kernel. Besides, we extend and optimize the Linux kernel modules, and implement frewall system with the packet fltering, content fltering and protocol fltering as a whole. The tests show that system has the perfect functions with the features of small scale and low cost.%　　文章基于ARM处理器的硬件构架，通过移植Linux内核建立嵌入式开发平台，针对Linux内核模块进行功能扩展和优化，并实现了集包过滤、内容过滤和协议过滤功能为一体的防火墙系统。测试分析结果显示该系统不但具有完善的功能，而且具有体积小、成本低的特点。
