Embodiment Construction
[0029] Before introducing the present application, the technical terms involved in the embodiment of the present application are introduced first.
[0030] The fault database network generally refers to that each node in a network is associated with a fault database. Wherein, the fault database is constructed from fault logs on the node, and may include one or more fault keyword records, and each fault keyword record corresponds to a fault keyword appearing in a fault log.
[0031] A fault keyword refers to a keyword related to a certain fault. For example, if a power supply on a certain network device fails, the fault keyword may be a power failure.
[0032] A fault topic generally refers to a certain fault mode mined from the network in the fault database, and can also be called a fault item set, which consists of one or more fault keywords.
[0033] The fault community refers to the collection of multiple nodes that have the same fault, and the fault community corresponds ...

The invention provides a fault community detection method and a management node, and relates to the technical field of communication. The accuracy of fault community detection is improved. The methodcomprises the following steps: determining, by the management node, a fault database network, wherein the fault database network comprises a connection relationship of N slave nodes and a fault database of each slave node, the fault database of each slave node comprises one or more fault keyword records, one fault keyword record contains a fault keyword appearing in a fault log of the slave node,and N is an integer greater than or equal to 2; determining a fault subject set according to a fault keyword set, wherein the fault keyword set comprises at least one fault keyword, and each fault subject in the fault subject set is composed of at least one fault keyword in the fault keyword set; and determining a fault community matching each fault subject from the N nodes according to the connection relationship of the N slave nodes, and the fault keyword records contained in the fault databases of the N slave nodes.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to a faulty community detection method and a management node. Background technique [0002] With the continuous increase of the scale of the communication network, the types and numbers of faults caused by the equipment itself and communication in the network are becoming more and more. Due to the connectivity between devices, a fault on one device may cause a fault on other devices, causing some fault modes to propagate among multiple devices, resulting in a large area of devices being paralyzed. In the process of network maintenance, if the various failure modes and corresponding failure communities in the network can be understood in time, that is, the collection of devices with the same failure (for example, routers, switches, etc.), maintenance personnel can quickly locate the failure area and Eliminate faults to prevent them from propagating among dev...
