Performance Analysis of Large Scale Information Systems

首席研究员关注的是基本问题 在大型信息系统的设计中， 特别是图文电视和可视图文电视，是在过去十年中发展起来的。 这项研究将侧重于系统性能作为一个整体， 系统概念化、设计和实现的一部分。 它 将考虑信息系统可以 配置为提供良好且具有成本效益的性能 大量的用户。 研究课题包括： o在局域网上提供类似图文电视的信息 o使用本地用户终端储存器以加强图文电视 系统性能 o可视图文系统中广播的最佳编排 o连接时间有限的可视图文系统的性能 o具有多个数据库的可视图文系统

The Principal Investigator is concerned with basic questions that arise in the design of large-scale information systems, in particular, teletext and videotex, developed in the last decade. The study will focus on system performance as an integral part of system conceptualization, design, and implementation. It will consider methods by which an information system can be configured so as to provide good and cost-effective performance to a large number of users. The list of research topics include: o Teletext-like information delivery on local area networks o The use of local user terminal storage to enhance teletext system performance o Optimum scheduling of broadcast in a videotex system o Performance of limited-connection-time videotex systems o Videotex systems with multiple databases
