| With the rapid development of the technology of communication and information, nowadays, the internet has increased fleetly in scale and complexity. The devices have the characteristic of decentralization, the interfaces are diversiform, and the devices from different manufactory are independent comparatively, all above make the demand of building a multi-platform and efficient network fault management system become more and more heavy.This paper is achieved after consulting the latest pertinent research production and analysing the situation of the network fault management system. After considering the task of network fault management and the characteristic of alarm data synthetically, it completes alarm correlation analysis using mining sequential patterns of the data mining technology, establishes comparatively reasonable processing course of the operations in fault management, and actualize the function of fault management for network resources. In this paper, we innovate in the following points:(1)Design processing course of the operations, the framework of the system, and the structure of the database, considering the function requirement of the system.(2)Do research about how to establish the module of alarm correlation analysis, and analyse the method of data mining upon alarm data. Put forward a new mining arithmetic, and then bring forward an incremental mining arithmetic of alarm correlated rules. It resolves the repeated mining situation when the mining parameter is unaltered and alarm data is increased, and the efficiency of data mining is enhanced.(3)Bring forward the method of topology restriction, restrict the correlated rules mining using the topology connection knowledge between the devices in the network. It can decrease the error of mining result under the circumstance synchoronization clock maladjustment.(4)Make test to prove the performance and precise of the arithmetic adopted by the system, and test the functions of the system. |
