Realizing Filter Mechanism of CORBA Notification Service with Push Model in Network Management System

CORBA Notification Service extends Event Service with new characteristics of structured event, communication reliability, filter mechanism, QoS and so on. It makes CORBA have more message-oriented middleware features, and provides better assurance for the communication process. This paper illustrates some new characteristics of CORBA Notification Service. A filter 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.
