Application Research on Filtration Mechanism in CORBA in Network Management System
Huitao Zhang · Radio Engineering of China · 2007
The event service in CORBA has offered an asynchronous communication mechanism between the event supplier and the event consumer.However,this mechanism has some disadvantages in practical application.For example,the connections between the event supplier and the event consumer can not be preserved permanently;the event data that has not been sent also can not be preserved permanently;The QoS is not supported and so on.CORBA notification service is the expansion of the event service.With some new functions of notification service such as structured event,filtration mechanism and QoS,etc,it can be more adaptable in various kinds of environments,for example,managed devices request communication with higher level.This paper illustrates some new characteristics such as structured event,filtration mechanism and QoS,etc.in CORBA notification service.A filtration mechanism is proposed to implement the event report while applying CORBA notification service based on push model in the network management system.This 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.
