| 摘 要： | 研究服务网格中的服务质量(QoS)保障问题.定义基本QoS参数及量化要求,阐述QoS参数归一计算方法,提出一种基于整体QoS的服务匹配策略.该策略利用QoS约束的一致性和整体QoS特性进行网格服务发现与选择,从而减小满足最小服务要求的解空间.实验结果表明该策略有效提高了匹配服务的执行效率,满足了用户的QoS需求.

| Abstract: | The guarantee problem of Quality of Service(QoS) in service-oriented grid was studied.The basic QoS parameters of service-oriented grid and their measurements were defined.Then,a normalization method to compute the QoS parameters was described and a strategy of service matching based on whole QoS was proposed.This strategy used the consistency of QoS constraints and whole QoS properties to discover and select grid services,so that decreased solution space to satisfy minimum service requirements.The experime... |
