摘要
首先介绍了光传送网告警预处理系统的结构,然后分析了告警预处理系统的三大功能块,即告警信息库、网络拓扑信息库和告警相关性分析,重点研究了四类告警相关性规则的建立。最后利用Del-phi7.0和SQLServer2000开发了光传送网告警预处理系统,并且搭建了实验系统模型进行功能验证,实验结果表明:系统可以在毫秒级时间内对告警进行预处理,有效地过滤和屏蔽冗余告警信息。
At first, the framework of alarm pretreatment system of optical transport network is discussed, then three function blocks of alarm pretreatment system are analyzed, they are alarm information database,network topology information database and alarm correlation analysis, four kinds of alarm correlation rules which are used for alarm correlation analysis are mainly analyzed. At last, Delphi 7.0 and SQL Server 2000 are used to achieve alarm pretreatment system of optical transport network; and experiment system is built to test the real- ization scheme of alarm pretreatment system. The results indicate that the system can preprocess alarms in milliseconds, and effectively filter or shield useless alarms.
