摘要
DDS是对象管理组织(OMG)推出的数据分发服务规范,专门针对分布式实时系统中基于数据的发布/订阅架构。本文研究了一种基于DDS模型的信息分发方法,然后通过一个例子演示了这种信息分发方法。该方法可很好的满足某平台系统对于数据传输的高可靠性、高实时性的要求。
DDS(data distribution service) is the first comprehensive specification available for "publish-subscribe" data distribution, which is published by OMG. A data distribution method based on DDS is studied in this paper, and the application example is presented. The demands of reliability and real-time in some platform system based on this method are satisfied well with the data transmission.
