基于开放式架构的DDS研究与实现

DDS service research and implementation based on the open architecture

华睿2号嵌入式实时平台具备实时性、灵活性等优点。基于华睿2号开放式架构综合比较,选择合理的通信中间件技术,即使用DDS来构建数据分发系统。在华睿2号平台上适配DDS所需要的传输插件、硬件结构等,以完成DDS在华睿2号平台上的部署。在完成DDS基本的QOS配置同时,根据传输方式来配置额外的QOS策略。最后,在平台实现DDS的测试与分析。对比DDS-UDP传输,DDS-RapidIO传输、DDS-RapidIO-DMA传输、逐步升级与优化,达到高实时性、高稳定性、大数据量的要求。

Huarui-2 embedded real-time platform has the advantages of real-time and flexibility. This paper will choose reasonable communication middleware technology by comparison based on the Huarui-2 open architecture. Therefore we use DDS to build data distribution system. The project will be equipped transport plug-in and hardware structure to sup- port the DDS deployment on the Huarui-2 platform. Not only we complete the basic configuration of DDS, but also con- figure the additional QoS based on the transport mode. Eventually, do implement of DDS test and analysis. By making a comparison among the DDS-UDP transport, the DDS-RapidIO transport, the DDS-RapidIO-DMA transport, we upgrade and optimize the program, which meets the requirements of highly real-time and reliable and large quality of data.
