融合区分服务和速率调整的请求调度策略
A request scheduling strategy integrating differentiation service and speed adjustment
摘要
Abstract
Considering the difference of heterogeneous user demands for quality of service ( QoS ) and the energy con-sumption of cloud data centers , a request scheduling strategy integrating differentiation service and speed adjust -ment is proposed .The strategy divides an IaaS ( infrastructure as a service ) cloud data center into the rapid cloud with speed adjustment and the reliable cloud with fault restoration , then a novel hybrid cloud computing paradigm is investigated .Accordingly , a system model based hybrid queueing network is established .From the view of the av-erage response time of delay sensitive requests , the energy saving level of virtual machines in rapid clouds and the utilization of virtual machines in reliable clouds , the system performance of the request scheduling strategy is esti-mated.The effectiveness of the proposed strategy and the rationality of the established system model are verified by experiments .By constructing a system cost function and improving the Jaya intelligent searching algorithm , the pro-posed request scheduling strategy is optimized .关键词
