Service quality control method of data distribution service communication middleware

The invention provides a service quality strategy action method of data distribution service communication middleware, and designs a service quality strategy action process of data distribution service based on a data distribution service technical specification in order to solve the problem that communication nodes of traditional communication middleware are difficult to control data delivery, data life cycle and the like in communication. A QOS module aiming at different service quality strategy requirements is designed, and the functions of entity partitioning, grouping, user identification and the like are realized in the publishing and subscribing process; in the data transmission process, the functions of sample data arrival sequence, historical data retransmission, different priority entity data transmission, sample data storage, entity state monitoring, time-based sample filtering, ownership entity filtering, data delivery and the like are realized. According to the method, the difficulties that a tra
