Using Filtration Mechanism of CORBA Notification Service in Network Management System

CORBA notification service makes up shortages of event service in the communication reliability, QoS and filtration mechanism. This paper introduces some new characteristics in CORBA notification service such as structured event, filtration mechanism and QoS. A filtration mechanism is proposed to implement the event report while applying CORBA notification service based on push model in the network management system. The mechanism is more efficient in distinguishing different users and different events. Therefore, the transmission of event is more efficient, costs in processing are greatly decreased. The filtration mechanism based on CORBA notification service is not only applied in network management system, but also widely applied in other fields of CORBA notification service.
