摘要
CORBA事件服务提供了一种在事件提供者和事件使用者之间的异步通信机制。但该机制在实际应用中存在着诸如不支持事件过滤、不能永久存放事件提供者和事件使用者的连接或者没有发送的事件数据以及不支持QoS等不足之处。阐述了CORBA通告服务的结构化事件、过滤机制和服务质量等新特点,提出了将推模式的CORBA通告服务应用于网络管理系统以实现事件上报的过滤机制。该过滤机制的应用,可以有效区分不同用户和不同事件,使事件的传送更有效率,避免了处理上的浪费。
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 envireuments, 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.
