SimWare rti hello world: Webinar
The document discusses the integration of Data Distribution Service (DDS) with High Level Architecture (HLA) for real-time simulations, highlighting DDS's advantages such as automatic discovery, scalability, and support for heterogeneous networks. It presents DDS as a reliable communication backbone for military applications and outlines the functionality provided by a product called Simware RTI. Additionally, the document includes contact information for further inquiries.
