一种高可靠并行环网的研究与实现

摘要

In order to meet the industrial ethernet high availability and continuous operation requirements,a design of high available parallel ring structure based on analysis of the reliability of single ethernet ring is presented, and redundant processing algorithm can be implemented in Linux. The experiment shows that network can switch seamlessly with the result of 0 packet loss rate between sender and receiver when single network fails.%为了满足工业以太网的高可用性和不间断运行要求，通过对以太网单环结构的可靠性分析．设计了一种高可靠并行环网和冗余处理算法，并可在Linux平台下实现。实验表明，单网故障时，并行环网可无缝切换，收发终端间的丢包率为0。
