摘　　要：针对数据中心处理工作流负载时产生的运行费用问题,首先,分析并建立了考虑带宽和电力费用的工作流负载分配模型优化数据中心运营商支付的经济成本。然后,针对优化模型的特点,设计了启发式算法求解最小运行费用和工作流子任务在各个数据中心的分配方案。最后,采用真实的工作流负载拓扑和参数设置进行算例分析,对比3种不同类型的工作流负载拓扑和常见的两种工作流负载分配方法,结果验证了综合考虑带宽流量费用和电力费用模型对降低数据中心总运行费用的作用。In response to the issue of operational costs generated when processing workflow loads in data centers,a workflow load allocation model considering bandwidth and power costs is first analyzed and established to optimize the economic costs paid by data center operators.Then,based on the characteristics of the optimization model,a heuristic algorithm is designed to solve the minimum operating cost and the allocation scheme of workflow subtasks in various data centers.Finally,a real workflow load topology and parameter settings are used for case analysis to compare three different types of workflow load topologies and two common workflow load allocation methods.The results verify the role of the comprehensive consideration of bandwidth traffic cost and power cost model in reducing the total operating cost of the data center.
