The complexity of modeling and simulation networks is increasing each year. As new and more realistic models are federated together to create a comprehensive training environment, it becomes much harder to troubleshoot communication links between the simulations. ANALYSIM was created from the ground up to be a simulation data analysis, logging, reporting, routing, compression, and playback tool. Providing the analysis and troubleshooting aspect within the MIRAGE suite of products, ANALYSIM's simplistic design and ability to be modified quickly have made it an analysis tool of choice within the simulation community. ANALYSIM has been used in military and commercial simulation spaces successfully since its debut in 2002.
