CERTI? (http://www.cert.fr/CERTI/) - CERTI is a runtime infrastructure for distributed discrete event simulations developed at ONERA. It provides a set of services used by simulators to interoperate (such as object management, time management, optimization services, etc.). Using these services helps simulation reuse and interoperability. They are based on the HLA specifications. HLA is a standard for distributed simulations. It was developed by the US Department of Defense. The HLA was approved as an open standard through the IEEE (IEEE Standard 1516).
