摘要
详述了嵌入式实时操作系统VxWorks下双网卡冗余热切换技术的实现方法。文中在分析了PCI总线型网络适配器驱动装载机制及冗余切换原理的基础上,给出了相应的BSP配置和冗余切换的实现代码。该方案在实际项目中得到应用。
The implement method of redundancy switching technology of dual NIC is expatiated in this paper based on the platform of VxWorks RTOS. The loading mechanism of the driver of network adapter （PCI BUS type）, as well as elements of redundancy switching is analyzed. Then particular BSP configuration and the code of realizing redundancy switching is put forward. The method has been verified in actual design.
