Resource heterogeneity offers a new challenge to portability of resource critical applications such as multimedia or interactive applications. Under heterogeneous environments, a priori knowledge of available resources is not always feasible during the development stage. As a consequence, resource critical applications must probe dynamically the resources and reconfigure to adapt themselves to different computing environments. We propose a component-based framework, FRAME, and CSML to help people develop and deploy resource critical Java applications in a heterogeneous environment. Under FRAME, the assembly of an application is postponed to execution time so that the application may be customized by gathering resource information from the environments. CSML may help people develop components and specify the intended performance. Finally, an application, the GO game, is used to evaluate FRAME under various environments.
