摘　　要：针对现有网络故障检测方法不能同时满足检测时间确定、检测开销低、多点故障检测能力及工业控制网络拓扑适应性等4种能力,提出了一种基于布尔网络测绘的时间敏感网络多点故障检测方法。该方法分为离线准备阶段和在线检测阶段。离线准备阶段,检测流生成算法基于网络拓扑生成一组检测流集合。该检测流集合对网络拓扑的边进行覆盖。在线检测阶段,检测包按照预定义路径周期性地从源节点发送到控制器。随后控制器根据每个检测包的到达状态来推断发生故障的链路。实验结果表明,与现有方法相比,所提方法能够在确定的时间内准确地识别出多个故障链路,并且生成的检测路径集更少,满足上述的4种能力。In view of the fact that the existing network fault detection algorithms cannot meet the four requirements of determination of detection time,low detection overhead,multi-point fault detection ability and topology adaptability of industrial control network at the same time,a multi-point fault detection method of time sensitive network based on Boolean network mapping was proposed.The method was divided into offline preparation phase and online detection phase.In the offline preparation phase,the detection flow generation algorithm generated a set of detection flows based on the network topology.The detection flow set covered the edges of the network topology.In the online detection phase,the detection packet was sent periodically from the source node to the controller according to the predefined path.Then,the controller inferred the failed link according to the arrival state of each detection packet.The experimental results show that,compared with the existing methods,the proposed method can accurately identify multiple failed links in a certain time,and generate fewer detection path sets to meet the above four requirements.
