As greater numbers of end users run both multimedia applications and traditional desktop applications (word processing, spreadsheets, etc.) on the same distributed system (e.g., an office intranet or the Internet), the issue of how to provide adaptive quality of service (QoS) in a highly dynamic, shared, and heterogeneous resource environment becomes very important. While Java is an elegant solution to the heterogeneity problem, it lacks adaptive QoS support, which is critical to multimedia and other real-time applications. Our ERDoS (End-to-End Resource Management of Distributed Systems) project presents solutions to the adaptation problem. We will demonstrate our innovative content-based adaptation algorithm, embedded within the Java Virtual Machine (JVM) using a set of multimedia applications on a laptop computer running Linux.
