Research And Application Of Alarm Filtering In Network Management Systems

With the continual expansion of the scale of network, network management research has become one of the most popular research directions in IT industry. Telecommunication service providers need to construct a integrated, centralized, intelligent management system, in order to carry through effective management to telecommunication, to provide qualified services to customers and to improve the competitiveness of enterprises.Telecommunication integrated network management demands to collect and process the huge number of alarm data from the exchange network management, transmission network management ,data network management, dynamic environment network management and etc. It's one of the core tasks that designing and implementation effective filtering mechanisms of alarms to achieve filtering disrupt, void and secondary alarms rapidly and accurately, to ensure to prevent alarms storm effectively, to ensure the concern alarms and to detect, position and handle failure rapidly.Firstly, this article analyses the characteristic of the alarm data of telecommunication network in detail and minutely clarifies the common methods of alarm relativity analysis and association rule mining algorithm.Secondly, it probes into how to obtain the alarm association rule using data mining technology after the comparison of current alarm association analysis methods. On based of that this article constructs alarm filtering rule knowledge base and knowledge expression of every alarm filtering module and knowledge acquisition and updating methods.Lastly, based on the former analysis results, this article puts forward stratified alarm filtering model and alarm filtering project basis of module. Further more, it illuminates knowledge base rule matching and the methods to settle the collisions, the concrete implementation of alarm filtering mechanism and its application effects.In our country, it is not a long time to start the research and exploitation of local...
