In a distributed environment, the presentation of structured, composite multimedia information poses new challenges in dealing with variable bandwidth (BW) requirements and synchronization of media data objects. The detailed knowledge of BW requirements obtained by analyzing document structure can be used for efficient utilization of system resources. A distributed multimedia environment consists of various system components that are either dedicated to a client (e.g., client buffer space and BW) or shared across multiple clients (e.g., server buffer space and BW). A shared server could benefit from fine granularity advanced reservation of resources based on true BW requirements. Prefetching by utilizing advance knowledge of BW requirements can further improve resource utilization. The prefetch schedule needs also to be aware of the BW fragmentation in a partitioned server. In this paper, we describe the JINSIL middleware for retrieval of a composite document that takes into account th...
