摘要

磁盘速度的提高并没有跟上处理器和内存速度的提高。面对多媒体数据,传统的存储技术是低效和/或不充分的。本文提出了一种高效的多媒体对象分配策略。我们描述了一个多媒体对象模型,对象和存储设备的特点,以及碎片化策略。使用二部图方法将碎片映射到存储设备,使用成本函数确定对象的有效分配并平衡设备上的负载。

Multimedia object modelling and storage allocation strategies for heterogeneous parallel access storage devices in real time multimedia computing systems
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.<>
