Modeling and Evaluation of High-performance Publish-Subscribe System

To address the communication needs of real-time distributed applications, OMG published a specification called "Data Distribution Service for Real-Time Systems", which uses the data-centric publish-subscribe model. This specification provides a standard of software API, and can control, deploy a variety of QoS parameters for real-time systems. Based on the component technology, the article studies mathematical model of distributed publish/subscribe paradigm, evaluate for this high-performance system. We prove Publish/Subscribe systems based on middleware can meet the needs of high-performance and distribute data in high-performance and efficient way.
