Future distributed applications will need to support computing devices with a wide range of capabilities, varying network connectivity, increasing mobility of users, and a wide variation in load placed by clients on services. This paper presents DACIA, a framework for building adaptive distributed applications. In DACIA, distributed applications are viewed as consisting of connected components that typically implement data streaming, processing, and filtering functions. DACIA provides mechanisms for run-time reconfiguration of applications to allow them to adapt to the changing operating environments. Components can be moved to different hosts during execution, while maintaining communication connectivity with other components. New components can also be introduced along data paths, for example, to provide compression on low-bandwidth connections. Keeping communication overheads low is a significant challenge in designing component-based services. DACIA is designed so that communication costs among co-located components are similar to those of procedure calls. Performance results, as well as examples of adaptive services that can be built using DACIA are presented.
