The increased emphasis on the need for composability in simulations has led to architectures with server simulations that provide a service to several other simulations. One such architecture was the Joint Synthetic Battlespace (JSB) Spring Experiment 2002 architecture, which included a Common Synthetic Environment (CSE) server for atmospheric effects. The intent of using a CSE was to provide a standard model for all atmospheric effects. The common model would assist in the evaluation of sensor systems by removing any bias due to different environmental effects models. When the CSE server was proposed, it became apparent that the number of requests for environmental effect calculations might overwhelm the server, or cause excessive network activity. This paper examines the ability of the current architecture to scale operational levels. The paper also proposes modifications to the current architecture that can enhance the scalability of the architecture without impairing its composability.
