提出了基于经济模型的网格QoS控制机制,刻画了基于经济模型的网格QoS管理结构。用生产一消费模型给出基于多QoS指标的全局QoS优化模型,用整数规划中的背包问题形式化描述了以用户QoS效用函数为导向的资源分配问题。这种形式化描述将用户的QoS需求、资源稀缺以及服务成本等网格关键因素统一在一个框架中分析,提出用价格和契约来控制网格QoS的策略。
Economics-based QoS control mechanism is proposed in grid environment. Firstly, economic grid QoS architecture is presented. Secondly, apply/supply demand model of microeconomics to optimize objectives of multiple dimension QoS. A simple integer program formulation, which generalizes well-known knapsack problems, describe QoS-aware resource allocation problem. This formulation allows us to incorporate factors such as resource scarcity, users' demand, and operating cost in a unified framework. Finally, price service and QoS contract are put forward.
