摘要: 以社会学中的人际关系信任模型为基础,提出了一种基于服务消费者的服务满意度评价、推荐者的服务推荐和第三方服务性能反馈的可信度量模型。将用户对服务资源的信任需求和服务资源的可信度并入DLS算法得到可信动态级调度算法CTDLS,从而在计算调度级别时考虑服务资源的可信程度。模拟实验表明,该算法能有效满足任务在信任方面的服务质量需求,对提高任务调度的成功率具有实际意义。
Abstract: Based on interpersonal trust model in sociology, a trust evaluation model is proposed based on users’ past experience with service provider, friends’ recommendations and third party’s feedback. By combining users’ trust requirement for service resource together with trust degree of service resource and dynamic level scheduling(DLS) algorithm, a novel scheduling algorithm was proposed that was called trust-aware dynamic level scheduling algorithm in cloud environment(CTDLS).The algorithm takes the cloud service resources’ trust degree into account when calculates the scheduling-level of task-resource pairs. The simulation experimental results show that such algorithms can effectively satisfy the tasks’ trust requirement and improve the success rate of parallel tasks scheduling in practice.
