基于多代理的网格资源高可用信任调度模型

Multi-agent-based Grid Resource High-available Trust Schedule Model

网格作为高度异构的环境,其随机性、动态性是网格的本质特点之一,也是开发和应用网格的一个难点,这种本质特点造成了网格应用环境的不稳定性。该文分析了网格的资源随机性和动态性特点,对资源进行分类,将信任引入到资源调度过程中,提出了基于智能Agents的网格资源高可用信任调度模型,以提供稳定可靠的品质服务QoS。

The grid is a highly heterogeneous environment that can potentially provide seamless, fast and efficient access to range of resources that are distributed over a wide area. The major characteristics are stochastic and dynamic. It is a difficulty for the development of grid application. This paper analyses the stochastic feature of grid and catalog grid resources. Trust is integrated into the resource schedule, and the multi-agent-based highavailable schedule model for providing the steady credible QoS is presented.
