Problems solved by technology

The defect of this analysis is that the results of its analysis are of a certain degree of credibility, and often require an additional, manual secondary confirmation process
Different people have different requirements for credibility, and it is difficult to unify
In addition, it is also an offline analysis, it is difficult to provide real-time analysis results, and online adjustment, processing

Embodiment Construction

[0072] figure 2 It is a network management system (NMS) frame diagram showing alarm correlation analysis according to an embodiment of the present invention.

[0073] Such as figure 2 As shown, area A and area B belong to two different managed networks (Managed Network) 2000 and 3000 respectively. Interconnections across networks / domains exist between the managed networks 2000 and 3000 . The managed networks 2000 and 3000 exchange information with the NMS (Network Management System, network management system) 1000 based on the SNMP simple network management protocol.

[0074] Firstly, the NMS 1000 has a fault management module 1010 (Fault Management, may be referred to as FM for short) and a network topology management module 1020 (TOPO Management, may be referred to as TM for short).

[0075] The network topology management module 1020 mainly provides management for MOR (Managed Object Repository, managed object warehouse). Here, the purpose of MOR is to maintain the de...

Abstract

The invention provides a fault management analysis system and method capable of finding root cause alarms. The fault correlation analysis system of the present invention is used to perform fault correlation analysis on the faults generated by the managed network to find out the root cause of the fault, and the managed network and the fault correlation analysis system perform information interaction based on a specific network management protocol, wherein, The fault correlation analysis system has: a fault management module for fault management; and a network topology management module for maintaining the managed network, wherein the fault management module has: an alarm for core processing of fault alarms A core processing module; and an alarm correlation module for performing correlation analysis based on a specific logical relationship based on the obtained alarms to find out the root cause of the fault. Thereby, it is possible to find out the root cause alarms and avoid repeated alarms or non-root cause alarms.

Description

technical field [0001] The invention relates to a telecommunication network management system, in particular to a system and a method for performing correlation analysis on faults in the telecommunication management system. Background technique [0002] SNMP (Simple Network Management Protocol, Simple Network Management Protocol) has become a widely used management protocol in the field of telecommunication network management. In SNMP network management, when a device detects a fault, the device will send an SNMP Trap message to the NMS. The NMS receives and parses the SNMPTrap, generates corresponding alarm information, reminds maintenance personnel to pay attention, and promptly locates and repairs the problem based on the displayed alarm information. [0003] When a network failure occurs, a series of alarms will be triggered, but not all alarms reflect the root cause of the failure. In the current network management, a large number of repeated alarms or non-root cause ...
