Abstract
DDS (Data Distribution Service) is a set of API and interoperability protocol specifications developed by OMG. It adopts a datacentric publish/subscribe architecture to meet the demand of high efficiency and real-time communication, This paper designed a kind of DDS based on data distribution system and used in distributed simulation system at first through the analysis of DDS communication principle. Then, it achieved the system from the design of communication interface to the construction of distributed simulation system. And by means of Quality of Service (QoS) Strategy in DDS, the particularly modified QoS Strategy designed for distributed simulation system is proposed. Finally, through the analysis on effect of disturbance (system average transmission delay, jittering and the amount of packet loss) on real-time and reliability requirements of system, the test results indicates that The distributed simulation system based on DDS can meet the real-time and reliability of general distributed systems.
