Multimedia object modelling and storage allocation strategies for heterogeneous parallel access storage devices in real time multimedia computing systems
C.Y.R. Chen, Kingsley C. Nwosu, P. Bruce Berra · 2002
The improvements in disk speeds have not kept up with improvements in processor and memory speeds. Conventional storage techniques, in the face of multimedia data, are inefficient and/or inadequate. Here, an efficient multimedia object allocation strategy is presented. We describe a multimedia object model, the object and storage device characteristics, and the fragmentation strategy. A bipartite graph approach is used for mapping fragments to storage devices and a cost function is used to determine an efficient allocation of an object and to balance the loads on the devices.>
