CAREER: Scalable High-Performance Information Servers for Internet-based Multimedia Applications

PI: Prashant sheny互联网的快速发展，加上计算和通信技术的进步，导致了各种分布式多媒体应用程序的出现。实现这样的应用需要开发能够有效管理数据特征和应用需求异构的大型信息服务器。本研究的主要目标是开发可扩展的高性能资讯伺服器，以实现基于网际网路的多媒体应用，并利用本研究的成果来提高教育的有效性。提出的研究将解决三个关键问题：(i)设计一个可扩展的、基于网络附加存储的通用多媒体文件系统，（ii）设计一个协调的资源管理框架，以有效地管理大型服务器上的资源，以及（iii）设计一个多媒体代理缓存架构，以有效地将数据传递给广域网上的应用程序。解决这些问题的研究方法是折衷的，依赖于分析、模拟和原型实现的结合。建议的教学工作将侧重于多媒体系统课程的开发和多媒体技术的使用，以提高远程和课堂教育的有效性。建议的工作将：(i)开发以实践为基础的多媒体研究生和本科生课程，以及（ii）探索使用多媒体技术开发更有效的教学辅助工具。

PI: Prashant ShenoyThe rapid growth of the Internet coupled with advances in computingand communication technologies has led to the emergence of a varietyof distributed multimedia applications. Realizing such applicationsrequires the development of large-scale information servers that canefficiently manage heterogeneity in data characteristics andapplication requirements. The main objective of the proposed researchis to develop scalable, high-performance information servers to enableInternet-based multimedia applications and utilize the results of thisresearch to enhance the effectiveness of imparting education.The proposed research will address three key issues: (i) the design ofa scalable, general-purpose multimedia file system based onnetwork-attached storage, (ii) the design of a coordinated resourcemanagement framework for efficiently managing resources on largeservers, and (iii) the design of a multimedia proxy cache architecturefor efficiently delivering data to applications over wide areanetworks. The research methodology for addressing these problems iseclectic, relying on a combination of analysis, simulation, andprototype implementation.The proposed teaching efforts will focus on the development of acurriculum in multimedia systems and the use of multimedia technologyto improve the effectiveness of distance and classroom education. Theproposed effort will: (i) lead to development of hands-on,laboratory-based graduate and undergraduate courses in multimedia, and(ii) explore the use of multimedia technology to develop moreeffective pedagogical aids.
