摘要
为了更好地满足分布式系统对于实时性和可靠性的需求,对象管理组织(Object Management Group,OMG)提出了一套数据分发服务(Data Distribution Service,DDS)标准。将传统的客户/服务器(Client/Server system,C/S)模型与DDS中以数据为中心的发布/订阅(Data-Centric Publish/Subscribe,DCPS)进行对比,重点介绍了DCPS模型及模型中实体间的关系,然后基于DDS的开源实现设计并实现了一个简单的实时分发系统。
In order to better meet the real-time and reliability requirements of distributed systems,Object Management Group(OMG)proposes a set of Data Distribution Service(DDS)standards.This paper compares the traditional client/server model with the Data-Centric Publish/Subscribe(DCPS)in DDS,focusing on the DCPS model and the relationships between entities in the model.Then,based on the open source implementation of DDS,a simple real-time distribution system is designed and implemented.
