| 摘 要： | 针对以太网,在不降低网络安全性并且以透明的形式存在于网络节点中的情况,介绍了一种基于端口物理层(PHY)和ARM的网络监听方案。系统使用网络PHY芯片接收底层网络数据,通过MII总线传给ARM嵌入式处理器,由ARM处理器存储及解析网络数据包,实现了一种灵活的网络监听工具。获得的数据可以显示在LCD显示器上或通过USB接口发送给上位PC机.该系统不仅集成度高,运行高效稳定,并且功能的升级十分方便。

| Abstract: | A design of network monitor based on PHY and ARM is proposed,and this monitoring system,without any reduction of network security,is transparent in the Internet.To achieve a flexible network monitor device,this system receives,with PHY chips,the physical network data and sends the data,through MII bus,to ARM processor for processing,storage and analysis.The data could be displayed on LCD or sent to PC through USB.The system is highly integrated,stable and efficient,and also fairly convenient in upgradation. |
