Method and device for generating alarm correlation diagram and method and device for determining related alarm

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...

Problems solved by technology

[0004] The existing alarm correlation analysis technology mainly analyzes the alarm correlation through rules, but the rules need to be predefined. If an alarm can cause a chain reaction of related alarms, multiple rules need to be established correspondingly, and the correlation between different alarms is determined. High complexity, poor intuition, and the scale of the network is constantly expanding, the number of rules will inevitably increase accordingly, and it is difficult to maintain the network
