| 摘 要： | 针对云计算SLA中响应时间这一衡量云服务质量的重要指标,本文提出了一种DSIC(占优策略激励兼容)机制.在所有云资源提供商都是理性的这一共同知识假定下,DISC机制能保证云资源提供商显示真实的资源成本信息,云服务提供商以此为前提选择预算约束下能够在最短时间内完成用户任务的云资源提供商,从而达到优化用户服务响应时间的目的.本文对该机制的性能进行了严格证明,最后提出了一种寻找最优资源提供商组合的算法.

| Abstract: | Considering response time,one of the important indicators for measuring QoS of cloud computing services in SLA,in this paper,we propose a dominant strategy incentive compatibility mechanism.Assuming all the cloud resource providers being rational,the proposed mechanism in this paper ensures each cloud resource provider is willing to bid true resource cost information,and taking this as the prerequisite the cloud service provider can derive a way aiming to the shortest response time under the cloud user’s budget constraint and also choose optimal composition of resource providers for user’s job.Finally,we prove pivotal properties of mechanism proposed in the paper and present the optimization algorithm of response time. |
