摘　　要：分析了VxWorks系统下网络驱动的原理,讲述了如何在网络协议层和设备驱动层构造驱动,实现网络的冗余设计,采用该方法设计的冗余网卡驱动,可有效地进行故障切换,切换时间短、效率高。This paper discusses the key concepts associated with network device driver based on VxWorks system.It also realizes the redundancy network driver by constructing the driver in the network protocol layer and device driver layer.This method can realize hot switching of network communication when network occurs an error.It Improves the efficiency and shorten the switching time.

关 键 词：VXWORKS系统 冗余网络 网络协议栈 设备驱动
