Comparison of the experimental and simulation results for Distributed Virtual Environments applications framework

In our previous work we developed Caffe Neve framework that allows application developers to create flexible and extensible Distributed Virtual Environments (DVEs) applications from the distributed components. The components can serve as remote content sources that stream down interactive 3D content to the application integrator. Since DVEs are interactive, multi-user and networked systems, it is important to ensure good responsiveness and overall performances of the developed applications. We investigate the performance of the integrated applications to evaluate the framework capability. We conducted experiments and used OMNeT++ simulation tool to explore the scalability issues. We use various metrics such as the response latency and service load estimation to evaluate the framework performance.
