摘要
以太网技术是当前应用最广泛的局域网技术。文章介绍了一个在中档路由器中的以太网协议的实现。该实现基于DEC21140为核心芯片，物理芯片可采用DP83840、BCM5000或ICS1890等多种芯片的以太网卡，以实时嵌入式操作系统pSOS为平台，实现了基本UNI接口以及动态配置功能，可以工作在10兆和100兆两种模式之下。
： Ether net is the most popular LAN technology in now days．This paper introduces an implementation of ether net in a middle－scale router．The implementation in this paper is based on ether net card whose core chip is DEC21140 and physical chip is DP83840，BCM5000 or ICS1890，the platform is pSOS，a real－time embedded operation system．It has realized the basic UNI and dynamic configuration，can operate in 10 million and 100 million mode．
