Research Initiation Award: Efficient Storage and Retrieval Techniques for Distributed Multimedia Servers

计算、网络和存储技术的最新进展有望创建一种基础设施，在该基础设施中，计算机系统将通过分布在高速网络上的交互式多媒体服务器来支持广泛的多媒体服务。 本研究的主要目的是通过开发以下技术来综合设计这种多媒体服务器的具有成本效益的系统架构：（1）最小化从盘到媒体块的平均访问时间的有效盘调度算法，（二）多媒体服务器可以采用的一种新的接纳控制算法，以在保证服务质量的同时最大化同时被服务的客户端的数量不违反任何客户端的要求，以及（3）用于盘阵列的多分辨率多媒体对象的有效放置（包括所需的复制和分发）的算法。 算法和协议，被发现是有前途的，将在一个原型分布式多媒体存储服务器的实施和评估。***

9409666 Vin Recent advances in computing, networking, and storage technologies promise to create an infrastructure in which computer systems will support a wide range of multimedia services through interactive multimedia servers distributed over highspeed networks. The main objective of the research is to synthesize cost-effective system architectures for designing such multimedia servers by developing: (1) efficient disk scheduling algorithms which minimize the average access time to media blocks from disk, (2) novel admission control algorithms that a multimedia server can employ to maximize the number of clients being serviced simultaneously while assuring the quality of service requirements of none of the clients are violated, and (3) algorithms for efficient placement (including replication and distribution as desirable) of multiresolution multimedia objects of disk arrays. Algorithms and protocols that are found to be promising will be implemented and evaluated in a prototype distributed multimedia storage server. ***
