Abstract
According to the node distribution, data heterogeneous and task dynamic characteristics of distributed systems,the functionality and performance of middleware are studied, and a real-time middleware was designed and implemented based on publish/subscribe mechanism.Adopting the idea of hierarchical design, the construction of middleware was completed from three aspects of model layer,communication layer and support layer in order to make it have the function of data synchronization based on distributed object, publish and subscribe communication mechanism based on Ethernet, Object real-time performance protection mechanism.Experiments showed that the middleware satisfied the needs of distributed system applications,and ensured that the end-to-end data communication delay was less than 1 millisecond,which meet the requirements of real-time data distribution in distributed applications.关键词
