| Abstract: | Data Distribution Service （DDS） published by Object Management Group （OMG） is a specification on data distribution service suitable for distributed real-time systems, which adapts to the requirement of new generation of avionic system for aviation communication platform. This paper researches the reliable transmission mechanism of DDS, which improves the transmission reliability by adding message sequence number and re transmitting missing data. This real-time and reliable communication method has important instruction value for the research of aviation real-time data distribution. |
