摘    要:针对云计算环境下用户所需资源与服务资源规格不完全相符以及在资源预留过程中完整资源被切割而产生的资源碎片问题,提出一种云环境下考虑碎片资源重利用的动态资源管理策略。研究了云计算环境下资源碎片的形成原因,构建了碎片资源池,制定了任务对碎片资源接收的度量标准,在充分考虑当前任务对资源查找、调度、匹配的同时,进一步讨论了任务调度对资源的分割情况,进而指出资源碎片对后续任务接收能力的影响,搭建了云计算环境下动态资源碎片调度模型。理论分析和Cloudsim仿真实验证明,该资源管理策略能有效实现碎片资源的优化重组,提高了资源对后续任务的接收能力,与此同时保证了较高的资源利用率。

关 键 词:云计算  碎片资源  动态资源管理  碎片资源调度  资源预留

Abstract:Concerning the problems that resources specifications and services required by users were not entirely consistent and the full resources were cut into debrises in the process of resource reservation in cloud computing environment, a dynamic resources management strategy considering the reuse of debris resources was put forward. The causes of debris resources were studied to construct debris resource pools, and the metric was made to measure how many tasks the debris resource could receive. While taking full account of the current task for resource discovery, scheduling, matching, the resource partitioning was further discussed by task scheduling, and the influence of the receiving capacity of subsequent tasks of resources debris was indicated. Finally, a dynamic resource debris scheduling model was built. The theoretical analysis and Cloudsim simulation results prove that, the resource management strategy can achieve resource optimization and reorganization of resources debris effectively. The strategy can not only improve the resources reception capability for subsequent tasks but ensure high resource utilization.
