【摘要】 网格作为建立在互联网之上的新一代技术,在国内外的学术界和工业界都引起了广泛的关注。不同于传统的分布式计算,网格将网络、通信、计算和信息结合起来形成一个虚拟平台为用户提供一体化信息和应用服务。本文结合近年来国内外对网格技术的研究成果,对网格的概念、网格的体系结构及网格的应用进行了论述,并结合现有的网络技术,对网格通信中存在的问题进行了分析总结,其中包括网格通信的协议、网格带宽管理、网格环境下的高速网络性能分析和基于策略的网格管理。最后,本文从网格QoS特性、网格QoS保证机制、基于QoS的网格体系结构及网格参数等四个方面着手,对网格QoS进行了理论上的研究,并通过实验对两种网格QoS支持体系GARA和G-QoSM进行了分析比较。更多还原

【Abstract】 As a new generation of technology based on the Internet,the grid is widely paid attention to within academia and industry circles both domestically and internationally. Distinguished from conventional distributed computing,the grid combines networking, communication, computation and information to provide a virtual platform for users with an integrated information and application services.Based on the researches on domestic and international grid technology in recent years, the concept, architecture, and the application of the grid are discussed in current paper. Combined with existing network technology, several grid communicating issues, such as the grid protocols, grid bandwidth management, analysis of high-speed network performance in grid environment and policy-based gird management are analyzed and summarized. Finally, some in-depth studies on theories are done based on the characteristics of grid QoS,the guarantee mechanism of grid QoS,QoS-based grid architecture and grid parameters, and the simulation experiments are designed to analyze and compare the two kinds of grid QoS supporting system, GARA and G-QoSM .更多还原
