    A Statistical Admission Control Algorithm for Storage Systems with Mixed Multimedia Workloads

    • 摘要: 混合类型多媒体负载访问存储系统是一个复杂的过程,不同类型的多媒体应用要求存储系统提供不同的服务质量保证.存储系统需要一个有效的访问控制算法,为尽可能多的多媒体应用提供保证服务质量的服务.对混合类型多媒体负载访问存储系统的访问控制问题进行了系统的研究:定义多媒体应用访问存储系统的服务质量参数;建立并发多媒体应用的汇聚负载模型;推导出混合类型多媒体负载的访问控制约束条件;实现相应的统计学访问控制算法.仿真实验的结果表明,新的存储系统访问控制算法是有效的,并具有相当高的精确度.

       

      Abstract: Retrieving data from the storage systems with mixed multimedia workloads is a complex process. Different classes of multimedia applications need the storage systems to guarantee different requirements of QoS (quality of service). In order to support as many multimedia applications as possible, the storage systems need an effectual admission control algorithm. A systematic research on this problem is carried on in this paper: the QoS parameters of the multimedia applications are clearly defined, the workload model of aggregate multimedia applications is established, and the constraint condition of admission control is derived. Based on the workload model and the constraint condition, the statistical admission control algorithm is implemented. The simulation experiments show that the novel algorithm is efficient and accurate enough.
