Self-adaptive real time message subscribing and issuing system and method

Abstract

The invention relates to a system and a method for self-adaptively subscribing and publishing realtime message. The system comprises a client service interface, a primitive resolver, a message manager, a subscribe manager, an event monitor, a condition evaluator, a message receiving thread, a message publishing thread, and a message transmitting thread. The invention overcomes the disadvantages of prior art to convert the subscribed object and the trigger rule by the primitive resolver to achieve conditioned message transmission and publish. By adopting the publishing rule of event-condition-publish manner, the invention achieves self-adaptive message communication mechanism and filters each message that is published realtime in the message publish process, sorts the messages in consideration of the transmitting condition and the message priority required by user, and publishes the messages, thereby saving the network resources and improving the flexibility and reliability for message publish and subscribe.

Description

technical field [0001] The invention relates to a system and method for message subscription and release, belonging to the field of computer communication. Background technique [0002] The communication mode required by distributed real-time applications is different from the traditional object reference mode. Multiple control systems or nodes connected through the network need to communicate messages in real time, so as to understand the state changes in the application environment and respond in time. Traditional synchronous object interface calls such as CORBA or RMI are point-to-point communication methods, while distributed applications need periodic data communication to keep abreast of changes in the environment, so the message communication mechanism based on the subscription / publish model is very suitable for this type of application system. However, the real-time message subscription / publishing system must solve: the filtering of messages, the balance of real-time...

Problems solved by technology

In this method, the message filtering under specific conditions is realized by sending a password identifier, that is, the messages without confirmation of the source by the subscriber are filtered, and all the messages of the confirmed source are published, without considering issues such as the expiration and real-time nature of the messages in the confirmed source messages. Occupies a lot of network resources and is not flexible
