Abstract

Disclosed in an embodiment of the present invention are a fault location method and device, the method comprising: extracting the alarm information of each device in a network, and establishing a correspondence between an alarm name and an alarm fault cause in the alarm information; according to a fault location target, merging and classifying the alarm fault causes to obtain a set of alarm fault causes; acquiring the alarm set of alarm data in a current network, and establishing a correspondence between the alarm set and the set of alarm fault causes, the alarm set comprising a set of alarm names; determining the probability of the fault cause occurrence corresponding to the alarm set in a preset time window, and selecting the probability of the fault cause occurrence satisfying a preset range as the fault cause of the alarm set; and hierarchically merging and classifying the fault causes of the alarm set to realize hierarchical locations of the fault causes. The embodiment of the present invention solves the technical problem in the prior art of inaccurate fault location and low location efficiency.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a fault location method and device. Background technique [0002] When a network device (network element) is running, it will generate different alarm information according to its own operating status and environmental changes. The alarm information includes: alarm reference documents and alarm failure reasons, and the alarm information will be sent to the network management system, so that The network management and operation and maintenance personnel check the possible fault causes according to the alarm reference document in the alarm information, so as to locate the cause of the network fault. However, since the network management system collects a large amount of alarm information, and there are also a large number of prompt alarms and derivative alarms, the efficiency of fault location for network management and operation and maintenance personnel based on the alarm inform...
