Experiments in Adaptable Distributed Systems

Bharat BhargavaCCR-9901712适应性系统可以在执行期间根据其环境优雅地重新配置。目前正在进行一系列试验，以制定适用于应用程序、系统和网络层的策略，以满足服务质量要求。研究了系统约束在确定可保证给用户的服务质量方面的影响。正在确定将在应用程序和系统软件中实施的适应性准则和机制。评估了适应性在满足不同应用中的服务质量要求方面的影响。重点研究了两个基本问题：分布式系统的自适应机制和基础设施以及自适应的服务质量提供和控制。这将导致制定关于系统适应性及其对各种应用的影响的专家规则/准则。这将允许研究系统软件的行为及其对电子商务等各种新兴应用的影响。数字图书馆和视频会议系统。这项研究将允许使用先进的系统服务、协议、技术及其实验评估进行实验。该知识适用于协作计算、分布式文件系统、多媒体应用和实时处理中使用的各种系统软件。

Bharat BhargavaCCR-9901712An adaptable system can gracefully reconfigure based on its environment during execution. A series of experiments are being conducted that will lead in the development of policies for adaptability at the application, system, and network layer to meet the quality of service requirements. The impact of system constraints in determining the quality of service that can be guaranteed to the user is investigated. The adaptability guidelines and mechanisms that will be implemented in the application and system software are being identified. How adaptability impacts in meeting the quality of service requirements in different applications is evaluated. The focus is on two fundamentals research problems: Adaptability mechanisms and infrastructure and Adaptable quality of service provision and control for distributed systems. This will lead toward developing expert rules/guidelines for system adaptability and its impact on various applications. This will allow the research on the behavior of system software and its impact on various emerging applications such as electronic commerce. Digital libraries, and video conferencing systems. This research will allow experiments with advanced system services, protocols, techniques and their experimental evaluation. This knowledge is applicable to various system software used in collaborative computing, distributed file systems, multimedia application, and real-time processing.
