摘　　要：本文提出一种受用户级QOS驱动的分组调度算法，主要基于对云QOS的属性分析，对经济云下现有的DBC调度算法进行了扩展和改进。在满足任务的截止期限和预算的范围内，根据任务是否具有高的网络带宽进行分组。通过把基于用户专有的QOS的需求加入到常规分组调度算法中，从而形成了一个基于网络带宽的分组调度算法。仿真结果显示：在模拟的云环境下，本文算法拥有较高的吞吐量和任务完成率。This paper, mainly based on the analysis of the attributes of the cloud QoS, proposes a packet scheduling algorithm driven by user QoS, and the DBC scheduling algorithm is extended and improved. Within the deadline and the budget, the task is grouped according to whether it has a high network bandwidth or not. A packet scheduling al- gorithm based on network bandwidth is formed by adding the requirement of users＇proprietary QoS into the conven- tional one. The simulation results show that the proposed algorithm has higher throughput and task completion rate in the simulated cloud environment.
