摘要
DDS实时发布-订阅模型无中心,多备份特点给通信数据的管理带来了完整性和一致性的问题。不同于P2P分布式存储,DDS应用具有硬实时、数据量较少的特点,其数据处理的核心问题是在不明显影响实时性的情况下,保证分布式系统中数据的完整性和一致性。文中基于DDS使用的通信模型,研究分析了在此种通信模型下引发的持久化数据管理问题,并给出了相应的解决方案。
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.
