As part of our future research direction, we are extending Mitra in several novel directions. First, we have introduced techniques to support on-line re-organization of data when additional disks are introduced to a system that has been in operation for a while [GK97]. These technique modify the placement of data to incorporate new disks (both their storage and bandwidth) without interrupting service. Second, we are investigating several designs based on request-migration and object replication to minimize the startup latency of the system [GK96]. Third, we are evaluating techniques that speedup the rate of display to support VCR functionalities such as fast-forward and fast-rewind. These techniques are tightly tied to those of the second objective that minimize the startup latency of a display. Finally, we are investigating distributed buffer pool management technique to facilitate sharing of a single stream among multiple PMs that are displaying the same presentation. The buffer pool is distributed across the available DMs. However, its content is controlled by the Scheduler.
