基于QoS约束的计算能力调度算法研究

云计算具有很强的商业性特点,以为用户提供高质量的服务为目标。针对云计算对服务质量QoS的需求问题以及云计算原有计算能力调度算法没有考虑用户多样性的缺点,提出了基于QoS约束的计算能力调度算法。该算法可以在保证为用户提供模拟的独立计算能力基础上,根据QoS参数生成的向量进行资源与任务的匹配,区分用户的不同服务质量需求,为用户提供符合其需求的资源。

Research on Capacity Scheduling Algorithm Based on QoS Constraints

Cloud computing has a strong commercial characteristics,that provides users with high quality services.According to the demand for quality of service QoS for cloud computing and cloud computing shortcomings of existing capacity scheduling algorithm,the capacity scheduling algorithm based on QoS constraints is presentsed in the paper.Based on the guarantee to provide users with simulation independent computing capability,the algorithm can matching resources and tasks by QoS parameter generating vector,and distinguish between different user service quality requirement,provide users with its demand for resources.
