Design of real-time distributed system using DDS

Data-centric design is a modern method for building advanced real-time distributed system. DDS (Data Distribution Service) is an API specification and an interoperable wire-protocol that defines a data-centric publish-subscribe architecture for connecting the anonymous information providers with the information consumers. The DDS APIs also allow data providers and consumers to present type-safe programming interfaces which are well suited for data-critical real-time distributed systems and QoS-enabled applications. The goal idea of this paper is to present a kind of real-time distributed system based on DDS and a general design of high level API which abstract the publish-subscribe process.
