Abstract:With the advent of the World Wide Web, there has been a fundamentalshift in the way information is exchanged among systems connected tothe Internet. There has been significant research in developingtechniques for eliminating performance bottlenecks arising due to thelack of sufficient CPU, disk, and network bandwidths. While thisresearch has led to greater understanding about building a Webmiddleware, it is not clear how a Web middleware can provide servicesthat can be customized to suit the needs of end users.This research project aims to investigate two key ideas - support fordifferentiated level of services and extensibility of the Webcomponents - to make a Web middleware more responsive and adaptive.The research will first develop components that can control andregulate allocation of resources to different requests. The researchhere encompasses development of a quality of service (QoS) model withrespect to services and resources provided by the components,exploration of QoS architectures, extension of the QoS model over awide area network, and investigation of a QoS model for webcaching. The project will then develop components whose behaviorcan be customized to suit user preferences, Web object characteristicsand operating conditions.

翻译后摘要：随着万维网的出现，已经有一个fundamentalshift的方式信息交换系统之间连接到互联网。在开发技术以消除由于缺乏足够的CPU、磁盘和网络带宽而产生的性能瓶颈方面，已经进行了大量的研究。虽然这项研究使人们对构建Web中间件有了更深入的了解，目前还不清楚Web中间件如何提供可定制的服务以满足最终用户的需求。本研究项目旨在研究两个关键思想-支持差异化的服务级别和Web组件的可扩展性-为了使Web中间件具有更好的响应性和适应性，本研究首先开发能够控制和调节不同请求的资源分配的组件。本文的研究内容包括：开发一个服务质量（QoS）模型，描述组件提供的服务和资源，探索QoS体系结构，在广域网上扩展QoS模型，以及研究Web缓存的QoS模型。该项目将开发组件，其行为可以定制，以适应用户的喜好，Web对象的特点和操作条件。
