摘要
通过分析VxWorks网络协议栈和82559增强型网络驱动程序的工作机制,并结合网络交换机原理和网络路由原理,提出了在驱动层实现双冗余以太网无扰动自动切换的解决方案,达到了双网口同IP地址、同MAC地址的效果。用低廉的成本满足了双冗余以太网的技术要求,确保了双冗余以太网的高效率和高可靠运行。
On the basis of analyzing the VxWorks ethernet protocol stack and 82559 end driver, using ethernet switch elements and ethernet routing principle, a solution of bouble redundant ethernet on driver layer is presented. This low cost solution achieves the effectiveness of double ethernet interface using the same IP address and same MAC address so as to guarantees high efficiency and high dependability of double redundant ethernet.
