Abstract
This research investigates integrating the Distributed Interactive Simulation (DIS) protocol with modern cloud computing technologies to enhance interoperability and performance in geographically distributed simulations using the internet. The study employs the Microsoft Orleans framework, an open-source implementation of the actor model, to develop a prototype for managing DIS protocol data units (PDUs). Tested in a realistic distributed setting, the solution’s scalability and performance were evaluated against the IEEE Standard for DIS—Communication Services and Profiles (IEEE 1278.2-2015). The latency of the PDU messages was compared to quality-of-service benchmarks. Initial tests with varying numbers of units showed adequate performance. The proposed solution successfully handled increased simulation complexity and network load produced by running an exercise that included fire exchanges between two antagonistic forces. While the solution did not consistently meet the 300-millisecond latency threshold established by the standard and the number of participant units was relatively small (less than three per side), it demonstrated the viability of such endeavors. Further optimization and architectural changes, such as workload distribution and leveraging Azure’s advanced features, are recommended. The findings suggest that cloud computing technologies could potentially enable more efficient and scalable distributed simulations.
