Embodiment Construction

[0035] The alarm correlation analysis technology mentioned in the prior art analyzes the alarm correlation through predefined rules. In the case of many rules, the determination of the correlation between different alarms is complicated, difficult to implement, and poor intuition. An increase in the number of rules will increase the difficulty of maintaining the network. In order to solve the above-mentioned technical problems existing in the existing alarm correlation analysis technology, the embodiment of the present invention provides a correlation alarm determination method, which uses the alarm correlation graph to determine and generate alarms For other associated alarms, the alarm association diagram can simply and effectively reflect the association relationship between alarms, and is not limited by the network scale, easy to expand, and can more accurately and quickly find out the source of the fault.

Abstract

A method and device for generating an alarm association graph, and a method and device for determining association alarms are disclosed. The method for generating an alarm association graph includes the following steps: determining successively two topologic nodes connected physically according to a network equipment topologic graph; acquiring all the alarms currently contained in the two topologic nodes respectively, and searching the alarms therein having association relationships; classifying the alarms having association relationships according to alarm properties, and generating an alarm collection for each alarm type; determining that an association relationship exists between the alarm collection of a first alarm type and the alarm collection of a second alarm type when the calculated probability of the occurrence of the association relationship between the alarm collection of the first alarm type and the alarm collection of the second alarm type, exceeds a first preset probability value,, and displaying the association relationship on the alarm association graph. The method could reflect the association relationships between the alarms simply and directly, and not be restricted to the network size, and be extended easily.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of network management, and in particular to a method for generating an alarm correlation graph, a device for generating an alarm correlation graph, a method for determining an associated alarm, and a device for determining an associated alarm in the field. Background technique [0002] With the rapid development of communication network technology, communication services are becoming more and more abundant, from the initial telegraph and telephone services to IP (Internet Protocol, Internet Protocol), multimedia and other services. The diversification of communication services is accompanied by the diversification of equipment types in the communication network, which makes subsequent management and maintenance of the communication network more and more difficult. [0003] In the communication network, there is an association relationship between various network devices. When one of...
