Abstract:

Non- center and multi-replica of this DDS real-time pub-sub model brings integrity and consistency challenges for data management. Different from P2P distributed storage problem, DDS applications has hard real-time/less data characteristics. Data managements core problem is to ensure the integrity and consistency of the data in distributed systems under hard real-time environment. 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.
