| 摘 要： | 文中在对各种防火墙的综合比较的基础上,讨论了嵌入式Linux的优缺点,提出了一个基于嵌入式Linux实现硬件防火墙的方案．最后给出了实现该方案的各个步骤。并针对嵌入式系统的实时性要求和防火墙的性能要求,介绍了RTLinux(一种硬实时Linux API)和RTnet的原理,给出了基于RTLinux和RTnet的防火墙整体框架。采用本框架的嵌入式硬件防火墙在性能上优于纯软件防火墙,而在价格上低于纯硬件防火墙。

| Abstract: | On the base of comparison of all kinds of firewalls, discusses the advantages and disadvantages of embedded Linux,then gives a design of hardware firewall based on embedded Linux,lastly presents every step of it. For the real-time request of embedded OS and the performance of firewall, this paper introduces the theory of RTLinux(a kind of hard real-time Linux API) and RTnet,then draws a firewall framework using RTLinux and RTnet.The hardware firewall based on embedded Linux is better than software firewall in performance and lower than hardware firewall in price. |
