Distributed, real-time virtual environment (VE) architectures have traditionally been driven by quality of service (QOS) considerations, with little or no concern paid to security issues. With recent advancements in functionality, computing power and network bandwidth it has become practical to use VEs in sensitive areas such as product development with(More)
If large-scale shared virtual worlds are to be established on the Internet, they must be based on technologies that allow them to adapt, scale, and evolve continuously-that is, without their being taken offline. In the course of designing NPSNET-V, an architecture intended to satisfy these criteria through component-based dynamic extensibility, the authors(More)
The Extensible Run-Time Infrastructure, or XRTI, is an experimental implementation of proposed improvements to the High Level Architecture (HLA) [Kapolka 03]. The HLA, a middleware standard for sharing information between distributed simulation components, can act as the communications infrastructure for an enduring network of shared virtual worlds, but(More)
