A Design of Storage and Retrieval Schemes in aMultimedia

Due to the fact that the speeds of secondary storage devices have not improved relative to other computing technologies, a lot of eeorts have been devoted to intelligent and eecient ways of storing data of storing data to maximixe the bandwidth of a computing system. Many of those techniques have proven useful; however, with the advent of multimedia and its enormous real-time and size requirements, the problems of data allocation and retrieval have become even more crucial. In 1]]2], we describe some designs of eecient multimedia object storage strategies that strive to allocate multimedia objects with the objective of satisfying their real-time retrieval requirements. We utilize some fragmentation strategies, a cost function, and bipartite graph model to allocate multimedia data eeciently. In the development of the storage allocation strategies, some assumptions were made about the functionalities and capabilities of the controlling Multimedia Object Manager. Here, we describe the design of the storage and retrieval schemes for a multimedia object Manager (MOM) that controls our allocation techniques. We describe the multimedia object model, generation and aggregation of the Storage Elements (SEs), determination of SEs spanned by an I/O request, clusterization and parallelization of requests, storage and retrieval structures, and extension and reduction of objects.
