Abstract: Thin-client computation advocates the separation of application GUI and the processing logic as well as the centralization of the processing, hence to enhance the resource utilization, decrease the system cost, and improve the system security. This paper introduces SmartTerm, an ultra-thin-client for the distributed desktop-like computing environment. It discusses the technological issues in designing the SmartTerm system, and proposes solutions. A design and implementation instance of the SmartTerm system is presented basing on the RFB protocol. The SmartTerm system can be applied in many systems under the grid computing and ubiquitous computing environment, such as grid terminals, mobile devices, remote control device, etc.
