Data Distribution Service (DDS) is a communication middleware supporting a flexible, scalable and, real-time communication capability. EchoDDS is compliant with RTPS and DCPS specifications of the DDS standard. EchoDDS was implemented which represented an improvement on the event-handling mechanism, the message-receiving mechanism, and the history-cache management mechanism. For the performance analysis of the EchoDDS, tests and measurements were performed on domain discovery and data transmissions in various environments. Results from the test show that EchoDDS has a better discovery and data transmission performance than other DDS products, when transmission delays and QoS settings are the same. Moreover EchoDDS is more stable than others, because the standard deviations of test results from EchoDDS for every performance test were smaller than those of other products.
