NADS invite you to the commercial presentation of the new release of SimWare. SimWare 4.0 is the first Real Time Simulation framework fully compliant with IEEE HLA and OMG DDS standards. The right cohabitation of HLA and DDS enables the development of a simulation system like a Federation of Simulations Assets, fully interoperable with critical assets in a Net-Centric environment. In this presentation you will know about the fundamentals of SimWare framework, its architecture and how the cohabitation of DDS and HLA helps to the rapid development of a real time simulation system with a fully distributed and scalable architecture. You also will know how improve the interoperability of your simulation systems to a subsystems level.
