摘要 在当前的存储代价和多媒体数据库的高带宽要求下,多层次存储服务器越来越受到欢迎。给出一个局域网环境中基于三级存储器的多媒体数据库框架,包括多媒体服务器、协调控制服务器、快速交换网络和密户群。为了优化系统资源使用,协调控制服务器按照不同策略调度请求。给出一种新的有效的多媒体请求调度策略。 Given the present cost of storage and bandwidth requirements of large scale multimedia databases, hierarchical storage servers are becoming increasingly popular. An infrastructure of multimedia database in local network based on tertiary storage is presented. The multimedia database consists of a multimedia sever, a control server, a rapid switching network and a client group. In order to optimize the utilization of the system resources, the control server schedules th e requests according to different policies. A request schedule algorithm is given.
