Unexpected interruption of computer network service is common, which may bring great influence to society or production at some important times. However, unlike a single computer system, in a large computer network, when a failure occurs, it is often difficult to determine the exact location of the failure easily and concretely, but it needs relevant technical support. Therefore, it is necessary to have a fault management system to manage all the faults in the network scientifically, record the generation of each fault and related information, and finally determine and correct those faults to ensure that the network can provide continuous and reliable services. This topic is mainly to find out the research situation of this topic in recent years.
