摘要: 随着网格技术的发展,包括服务级别协商和服务级别保证的服务质量保障越来越重要。服务质量保障与资源分配有密切的关系,而服务所面临的访问流量的大量不可预知的变化使之更加复杂。该文定义和分析了服务质量保障、资源分配和访问流量的关系并建立了数学模型,将该模型应用到按需资源分配框架中,该框架能有效地保证服务质量,应对复杂多变的网格应用环境。仿真和实验结果证明了模型和框架的实用性和有效性。

Abstract: In grid environment, the quality of service assurance by SLA is becoming more and more important. Service level guarantee relies on the amount of resource allocated. And the large traffic variations of grid service complex the relationship. This paper formally defines and analyzes these relationships and presents a constrained mathematical model for resource allocation. It also presents the on-demand resource allocation framework which can guarantee the service level and adapts to environmental changes. The simulation results show that the model and framework are practical and efficient.

Key words: QoS, On-demand resource allocation, Grid Service
