摘　　要：集中式防火墙通常是设置在内网与外网之间的对输入和输出数据流进行即时监控的网络安全保护设施,其优点是易部署、效率高和响应及时,同时也存在部署成本高、控制策略实现难等不足。本文针对普通防火墙存在的问题及现有嵌入式防火墙的不足,改进设计一种基于AMR处理器的嵌入式防火墙。首先进行嵌入式防火墙的总体框架及软硬件架构设计,在此基础上对防火墙处理器选型、应用程序的关键技术进行详细研究,最后搭建试验床进行性能测试。测试结果显示该嵌入式防火墙通信性能良好,安全有效。A centralized firewall is usually set between the internal network and the external network for the network security facilities for real - time monitoring of input and output data flow. The advantages of the firewall are that it is easy for deployment, high in efficiency and fast in response. However, its disadvantages are that it is high in cast of deploy- ment, difficult in implementation of control strategy. According to the problems of common firewall and the disadvantages of embedded firewall, this paper designs an embedded firewall based on the AMR processor. The general framework and the architecture of software and hardware of the embedded firewall should be designed, based on which key technologies of processor type selection and application program of the firewall should be studied in detail and a testbed should be built for performance testing. The test results show that the embedded firewall has good performance and is safe and effective.
