摘　　要：网络驱动软件在嵌入式开发中起着重要作用,特别是在通过网络进行下载调试阶段。结合在开发过程中所用到的End(Enhancednetworkdriver)型网络驱动,着重分析了VxWorks系统下的网络结构及其网络驱动软件的开发。分析了开发End型驱动时所用到的数据结构,网络结构中各层提供的接口以及包的存储结构和收发包的过程。通过这些分析,用户可以了解驱动的工作原理,便于开发。Network driver is important in embedded systems designing, especially in the stage when loading the image through network. Based on the End network driver in the design, the paper emphasizes to analyze the network structure in VxWorks and show how to design the End network driver. The paper analyzes the structure to design the driver,the API in layers and how to receive and send pachet through the end driver. After this ,the designers can know the theory to design end driver and then design it.
