Abstract: DDS network middleware uses data-centric real-time publish/subscribe communication model has the characteristics of non- center and multi-replica, therefore, it brings integrity and consistency challenges for communication data management. In order to efficiently manage and maintain data intensive, and handle load balancing, a plurality of communication between nodes consistent with historical data for real-time publish/subscribe network middleware research design must face the challenge. This paper starts from the communication model used by the DDS and then analyzes persistent data management problems caused by such model, given a kind of appropriate solutions.
