摘　　要：针对Vxworks环境下单网卡通信可靠性不高的情况,在分析了PCI总线型网络适配器驱动装载机制及双网卡冗余热切换技术原理的基础上,详述了VxWorks环境下基于Intel 82559双网卡冗余热切换技术的实现方法,并给出了相应的BSP配置和冗余切换的实现代码;应用结果表明,双网卡冗余热切换技术的通信可靠性高,切换时间能达到ms级。Due to the lower reliability of communication on the platform of VxWorks RTOS with single NIC, the loading mechanism of the driver of network adapter （PCI BUS type）, as well as the principle of dual redundancy hot switching is analyzed, the implement method of redundancy switching technology of Intel 82559 dual NIC is expatiated in this paper based on the platform of VxWorks RTOS. The parti- cular BSP configuration and the code of the dual redundancy switching is put forward. The application shows that the dual-- NIC redundancy switching technology has a high reliability of communication, and the switching time can reach ms level.
