HLA, a DoD high level architecture, is emerging as an IEEE standard platform for large-scale distributed interactive simulation systems. It mainly emphasizes on the reusability and interoperability of different simulation components. However, HLA/RTI shows apparent weaknesses when it comes to distributed real-time simulation applications. In this paper, we propose a real-time RTI system, based upon a multi-threaded process model that addresses the weakness of HLA/RTI in terms of real-time applications. We discuss our real-time mechanism, and highlight the main design issues of our real-time RTI. We describe its implementations, and present an extensive set of simulation experiments to evaluate its performance using realistic models.
