Research on High Performance Multimedia Architectures


Multimedia data have demanding performance requirements due to their volume, bandwidth, and delay sensitive nature. This line of research aims to discover principles and algorithms for efficient multimedia management and delivery. Particular aspects that have been investigated involve modeling of disks of various kinds from the performance point of view, multimedia data placement on disks of various kinds based on their access frequencies, modeling of magnetic tapes and multimedia data placement on magnetic tapes, modeling tertiary storage (jukeboxes) and storage hierarchies, developing algorithms for stripping across disks, and digital video delivery across a network of heterogeneous clients so that quality of service criteria are satisfied. Multimedia data placement in the network and traffic adaptation are considered. Experimentation with large implementations and simulation is used to test the modeling and the algorithms.
