Network Alarm Filtering In Integrated Communication Network Management

With the continual expansion of the scale of network, requirement for high quality service from customer is increasing. Next-generation network architecture is become more and more integrated on the trend. Telecommunication service providers require a centralized, integrated, intelligent network management system to be constructed. The alarm relativity analysis is an important method for comprehensive network management system.The article firstly introduces the knowledge of integrated network management system and development situation, presents the basic of the alarm relativity analysis, and the available alarm relativity analysis methods are compared. As actual usage, the author proposed method the present relativity analysis method can not recognize the alarm course by maintenance. It make the alarm correlation analysis out of touch with the daily maintenance, affecting the practical alarm relativity analysis result.The article proposes the alarm relativity analysis should analysis the maintenance information. Based on the analysis the characters of the maintenance alarm, the article research the method of analysis maintenance information in the alarm relativity analysis. To put forward identify maintenance actions through the system logs and other methods. And the article discuss of the maintenance actions showing strategy in the presentation layer, put forward "maintenance of traces" present method, and the model of filtering network management alarm in alarm relativity analysis.To put forward that maintenance management system should proposed from static to dynamic management, to put forward maintain system should combine integrated network management system. It's consistent with the trend of maintaining unity.Finally, the experiment proved the effectiveness of maintenance action recognition mechanism. Experiments show that filtering maintenance alarm in the alarm relativity analysis effected well.
