A novel approach to real-time RTI based distributed simulation system

HLA, a DoD high level architecture, is emerging as a standard platform for large-scale distributed interactive simulation systems. It mainly emphasizes on the reusability and interoperability of different simulation components. HLA was well designed and has been proved to have the ability to guarantee the desirable properties of reusability and the interoperability in distributed simulation systems from several aspects. However, HLA shows an apparent weaknesses when it comes to real-time simulation applications. Indeed, there are no specific rules provided with respect to real-time applications in HLA specifications. Therefore, there has not been any widely accepted real-time implementation specification for the HLA Run-Time Infrastructure (HLA/RTI). In this paper, we propose a novel real-time RTI architecture which addresses the weakness of HLA/RTI in terms of real-time applications. We discuss our design and the implementation of our real-time RTI architecture with an emphasis on the real-time RTI end-system.
