With the application of information system in military field,information network requires better and better real-time information distribution.The real-time performance of information distribution depends on the communication model, the strategy of information distribution and the physical characteristics of the network itself. Open Data Distribution Service(OpenDDS) adopts a data-centric publish-subscribe communication model, which provides a better solution for real-time data communication in many information distribution networks. As a communication media, reflective memory’s storage and fast read-write mode can reduce network loss and improve transmission efficiency. Information distribution model is designed by combining reflective memory with OpenDDS and OpenDDS architecture , OpenDDS network communication and Datagram Inter-ORB Protocol(DIOP) are introduced. By studying the remote call communication process under DIOP, refective memory reading –writing data method and the monitoring hardware and multi-channel separation notification mechanism of Adaptive Communication Environment Reactor(ACE), using refective memory as the underlying communication media, the communication data is transmitted through reflective memory and DIOP by reflective memory network hardware design and OpenDDS software design. An information distribution technology based on reflective memory and OpenDDS communication model is proposed. Finally,the correctness of data transmission is verified by experiment.
