Event communication device and method

Abstract

This invention discloses an event communication device including: an event kind object unit used in generating an object and analyzing it, an event server used in creating event channels based on the channel distribution information and storing all event channel includes, in which, the distribution information includes the corresponding relation of event channels and the kinds, an event send unit used in obtaining the object of event kind from the upper layer event sender and getting the includes of said event channel from said server and setting up the sending proxy object to be connected to the channel and sending out the packaged information, an event receiving unit used in obtaining the includes of event channel from the event server to set up a receiving proxy object and connecting it to the channel to realize the reception of information and generating an event kind object and sending it to the upper event receiver. This invention also discloses an event communication method.

Description

technical field [0001] The invention relates to event service technology of a network system, in particular to an event communication device and method. Background technique [0002] With the development of information technology, more and more information is transmitted through the network. For example, in the network management system based on the Common Object Request Broker Architecture (CORBA, Common Object Request Broker Architecture), there are a large number of message transmissions between the various modules in the backstage and between the front and backstage, usually by events based on the CORBA notification (Notification) service. The server completes the forwarding of the message. [0003] The party that sends a message is called an event sender, and the party that receives a message is called an event receiver. In the prior art, the process of sending and receiving messages in the event communication method of the event service system based on CORBA Notifica...

AI Technical Summary

Problems solved by technology

[0031] The defect of this prior art is: since the CORBA Notification service uses the general event structure StructuredEvent, so the event sender needs to map its message structure into the event body of the StructuredEvent structure; the event receiver needs to take out information from the StructuredEvent structure and fill it into its In the message structure, it is more inconvenient to use

[0032] When using multiple channels to send events, the event receiver cannot find the corresponding event channel according to the event that needs to be received, and the event sender cannot directly connect to the corresponding event channel according to the event type of the message to be sent. The agreed method obtains the reference of the event channel from the naming service or other means, and the connection process is more complicated

[0033] To sum up, the process of using Notification directly by event senders and event receivers is complex and cumbersome, and the binding is relatively tight. If you need to modify the event channel allocation strategy, you need to modify the application code
