Abstract: The real-time performances of three common middleware technologies such as RTI, EVSM and ACE in distributed interactive simulation environment are tested and analyzed. The differences among them are explained, which probides reference for choosing middleware technology in the distributed interactive simulation system. Through the comparison, some facts are given: middleware technology is produced for distributed computing and processing system. It can make application program depart from operating system, so it becomes the key indicator to envalue the real-time performance of the whole system.
