Research And Design Of Message Service Components Queue Mechanism

With the development and application of information technology, it is the performance of distributed systems demands higher and higher, where the network transmission performance is becoming increasingly critical. Since the message can not only mask the hardware platform, middleware, operating systems, networks, and other differences, while reliable, secure and efficient network transmission, message oriented middleware as an important rapid application development tool.Based on this, where the research group of the design and implementation of a messaging service component that provides data for the application proxy function, shielding different hardware platforms, operating systems, networks, the gap between between to provide application to application efficient and convenient communication.Queue message service component is the core component for the message to provide safe, efficient and reliable services to ensure high performance. This service component of the message queue mechanism to expand the research and implementation, the main work is as follows:1) Components for the message service efficient, reliable, fair and other performance requirements, developed a suitable Message queue mechanism to service components. Ultimately be achieved on the components of efficient, reliable, fair and so do the performance requirements and address these needs, the corresponding specific queue. In order to improve component performance, the queue length of the column, the queue of internal data types, the number of queues, queue scheduling policy and so do a thorough study.2) The service component in the message queue mechanism to achieve the above and complete the test. Component in the message queue mechanism to do the design, design PSMQI interface layer, PSMSN core layer, PSNMS the interaction between the server level, communication models, and the internal layers will need to queue. Detailed design of the queue, the receiving transfer agent pool, receive transfer agent, the method of transfer agent receives the object data structure, and function data structure to do the analysis, describes the class data members, function members of the function. Completion of the message components within the class diagram, logic diagram, and the use of important functions. Upon completion of the implementation mechanism of the message queue component, based on its high performance was tested and the test results obtained in the follow-up.Finally a summary of the text, the follow-up study of the future are put forward.
