Research and application of alarm filtering in network management systems

With the growing number of telecommunication services,the number of alarm data of telecommunication network grows ex-ponentially.So to telecommunication integrated network management that collect and process the huge number of alarm data from the exchange network management,transmission network management,data network management,dynamic environment network mana-gement and etc,the first problem to solve is how to filter great alarm data problem.Stratified alarm filtering model and alarm filtering project basis of module is put forward to realize stratified converging alarm data fast based on analysis the characteristic of the alarm data of telecommunication network in detail.The warning relevant rule production algorithm is used,which the Apriori connection excavation algorithm and the event sliding window unifies to construct the warning association in time rule,the alarm filtering template intellectua-lized production is realized.
