摘　　要：本文提出了一种时间冗余的网络接口容错方法,使用记录表对每个请求数据包进行记录,并在奇偶校验检错模块检测到错误时进行快速重传,以保障网络接口的可靠性。本文对i.MX 28评估套件的网络接口进行了故障源分析,运用本文提出的方法设计了网络接口的容错方法,通过模拟网络接口故障注入实验对所提出的方法进行评估。实验结果表明,该容错方法降低了软错误导致的网络接口失效率,可以在较小的开销下提高网络接口的可靠性。In the paper,a time-redundant network interface fault tolerance method is proposed,which uses a record table to record each request data packet,and quickly performs a fast detection when an error is detected by the parity error detection module to ensure the reliability of the network interface.This paper analyzes the fault source of the network interface of i.MX 28 EVK,and designs a fault-tolerant method for the network interface by using the method proposed in this paper.The proposed method is evaluated by simulating the network interface fault injection experiment.The experiment results show that the fault-tolerant method reduces the failure rate of the network interface caused by soft errors,and can improve the reliability of the network interface with less overhead.
