摘要: 提出了一种基于滑动窗口的资源预留SWRR(sliding window based resource reservation)算法,它将预留资源在整个资源池中所占的比例称为窗口。窗口的“滑动”包含2层含义:1)窗口大小动态变化;2)窗口中的资源动态刷新。SWRR已被应用于一个大型的云计算应用平台。实验数据表明,SWRR通过合理资源预留,在兼顾所有任务调度的基础上,可为特定用户提供有效的服务可用性保障。
Abstract: A sliding window based resource reservation (SWRR) algorithm was proposed, in which a window is defined as the proportion of the reserved resources among all. The sliding of the window is twofold, adaptively window resizing, and dynamically window content refreshing. SWRR was applied to a large cloud computing platform. Experiments reveal that SWRR can provide high service availability for specific users while taking all users into account by proper resource reservation.
