Abstract:
To resolve the question of insufficient consideration for users’ preference Quality of Service(QoS) in the research of service grid resource mapping mechanism, this paper studies a mapping algorithm that ensures the multi-dimension QoS requests of users. After analyzing the multiple QoS properties of the grid resources, a method to screen out the correct grid resources which hits to the spot of QoS restricts of sub-tasks is presented. The corresponding mapping result and a QoS-Sufferage algorithm are put forward. This QoS-Sufferage algorithm is proved to be effective by the simulations taken on the GridSim platform.

摘要: 针对网格资源映射对用户的服务质量(QoS)偏好考虑不足的问题,对保障多维QoS的网格资源映射算法进行研究,从服务网格资源的多维QoS属性分析入手,在满足用户全局约束的前提下,根据服务中各子任务的QoS约束筛选出符合要求的网格资源,并给出合理的映射结果,提出一种网格资源映射算法——QoS-Sufferage算法。利用GridSim平台进行仿真比较,结果验证了算法的有效性。
