Abstract

The invention provides a method and a system for integrating RapidIO transmission by DDS communication middleware. The method comprises the following steps: a new model creation step, a RapidIO description model of a DDS-RTPS protocol is provided based on the DDS-RTPS protocol, and the brand-new RapidIO-based data transceiving model of the DDS-RTPS protocol is provided by utilizing the characteristics of UDP broadcasting, efficient UDP small data packet transmission and efficient RapidIO large data packet transmission. According to the invention, a DDS communication model of task electronic information system data based on a RapidIO underlying communication mechanism is realized, interfaces are uniformly accessed, efficient real-time distribution is realized, a uniform communication soft bus is provided for applications in the task electronic information system, and the communication efficiency and portability of the applications are effectively improved.

Description

technical field [0001] The invention relates to the technical field of middleware, in particular to a method and a system for integrating RapidIO transmission with DDS communication middleware. In particular, it relates to a method for integrating RapidIO underlying communication mechanism with DDS communication middleware based on international open standards, which can be used for efficient and real-time distribution of task electronic information system data based on RapidIO underlying communication mechanism. Background technique [0002] Data Distribution Service (Data Distribution Service, or DDS) is an open standard specification for data distribution in distributed real-time systems by the object management organization OMG. It is a data-centric publish / subscribe data communication model and standardizes application-level interfaces. And the behavior of data distribution service has the characteristics of anonymous communication, on-demand data distribution, one-to-m...
