CAREER: An Integrated Video-Based Storage System with Guaranteed Performance

数字图书馆、视频点播、电子商务、万维网等多媒体应用正以非常快的速度发展。这个为期四年的CAREER项目的主要目标是设计一个通用的高质量视频存储系统。目标是：(1)寻找静态视频文件分配问题的有效处理算法；(2)开发动态视频文件分配问题的理论框架；(2)开发动态视频文件再分配的理论框架；(3)研究新兴串行存储接口的有效软件设计。设计了一种在高速通信网络上保证应用质量的基于视频的存储系统（即中间件解决方案）。研究包括理论性能评估和通过实验系统进行测量。通过开发一系列多媒体系统设计课程和一个研究实验室，为学生提供设计、实现和测试所提出的基于高速局域网的高性能视频存储系统的设施，实现了研究和教育的整合。

CCR-9874726LiuMultimedia applications such as Digital Library, Video-On-Demand, Electronic Commerce, and World-Wide-Web have been developing at a very fast rate. The main objective of this four-year CAREER project is to design a generic high-quality video-based storage system. The goals are (1) to search for efficient processing algorithms for the static video file allocation problem, (2) to develop the theoretical framework for dynamic video file allocation problem, (2) to develop the theoretical framework for dynamic video file reallocation and (3) to investigate efficient software design for emerging serial storage interfaces. A video-based storage system (i.e., middleware solution) with guaranteed application quality over high-speed communication networks is designed. The research includes both theoretical performance evaluation and measurement through an experimental system. The integration of research and education is achieved by developing a series of multimedia system design courses and a research laboratory to provide students a facility to design, implement, and test the proposed high-performance video-based storage system over high-sped LANs.
