Embodiment Construction

[0024] Such as Figure 1-3 As shown in one of them, the present invention discloses an alarm correlation analysis method based on a graph data model. Specifically, the graph data model originates from Euler and graph theory, and can also be called a graph-oriented / graph-based data model. The basic meaning is to store and query data in the data structure of "graph". The data model of the graph is mainly embodied by nodes and relationships (edges), and can also handle key-value pairs. It has the advantage of quickly solving complex relational problems.

[0025] Graphs have the following characteristics: contain nodes and edges; nodes have attributes (key-value pairs); edges have names and directions, and always have a start node and an end node; edges can also have attributes.

[0026] A graph can be said to be a collection of vertices and edges, or more simply, a graph is a collection of nodes and relationships that connect these nodes. A graph represents entities as nodes ...

Abstract

The invention discloses an alarm correlation analysis method based on a graph data model. The alarm correlation analysis method comprises the following steps: step 1, constructing the graph data model: converting a relational database model into the graph data model; Step 2,performing fault marking: when a network fault event or a user complaint event is received, marking a corresponding node inthe graph data model as a fault; Step 3, performing alarm pre-association: taking out the node with the lowest hierarchy from the graph data according to a fault time window, and storing the node in apre-association result set; Step 4, carrying out root alarm association judgment to determine a fault root source: in a pre-association result, when a further association relationship does not exist,determining the corresponding node as the fault root source; And when the further association relationship exists, the node involved in the association relationship is the fault source. According tothe method, the relation model is converted into the graph model, the processing efficiency is improved, the service request can be quickly responded, and the scene of real-time processing and analysis of the network data is effectively supported.

Description

technical field [0001] The invention relates to the technical field of telecommunication data processing, in particular to an alarm association analysis method based on a graph data model. Background technique [0002] The existing network alarm correlation analysis is based on a relational database. When the network has many bearer layers and a large number of devices, the correlation relationship is incomplete, and there are problems of low correlation efficiency and inaccurate correlation. Real-time correlation processing of network alarms In the scene, the problem of low correlation efficiency is particularly prominent. [0003] The current prior art CN201711482171.2 (alarm correlation analysis method, device, equipment and medium) adopts a method based on alarm time distribution. This method can solve some alarm events that cannot be associated due to the lack of association relationship, but the alarm arrival time of different devices may vary greatly, and the setting...
