Abstract
In support of both the development of new tactics and ongoing training, military and other organizations rely on simulations. To support such requirements, the High Level Architecture (HLA) was developed. HLA provides a standard for the development and deployment of distributed simulations. As the complexity and scale of the events being simulated increases, the underlying HLA simulation likewise increases in scale and complexity. A key constraint in the performance of large-scale distributed HLA simulations is the ability of the distributed simulation components to communicate simulation state and coordinate their actions in simulated time. A key enabler for this communication and coordination is robust and reliable network communications. While the HLA standard provides simulation components both a best effort and a reliable communications transport, simulation developers often limit use of the reliable transport due to concerns about latency and throughput performance. The contribution of this thesis is to examine the performance of a specific high-performance HLA implementation, RTI-s, under controlled benchmark conditions to document the simulation performance tradeoffs of best effort and reliable transport under controlled, representative loads. A key part of this examination was the integration of the QuickSilver Scaleable Multicast protocol, developed at Cornell University, into the high-performance HLA implementation. Research was done on the nature of HLA simulations and the characteristics of reliable multicast protocols. Controlled benchmark experiments were conducted and analysis provided highlighting the tradeoffs between use of best effort and reliable protocols for HLA simulations. Finally, considerations for both an "ideal" HLA benchmark and an "ideal" HLA reliable transport are offered.
