| 摘 要： | 传统的Web服务框架不支持基于QoS的查询,不能满足用户对服务性能的要求。在传统的SOA框架上增加了QoS代理中心,并提出了两阶段的服务匹配算法。为了克服QoS动态变化的特点,通过QoS代理监控并记录以往运行的服务反馈的QoS值,来综合计算服务的QoS值。给出QoS记录权重随时间衰减因子,并描述了算法。实验表明该方法具有一定的可行性。

| Abstract: | The traditional Web service framework does not support QoS-based queries and cannot meet the performance requirements of service users.On the basis of the traditional SOA framework,the paper adds a QoS agent center and proposes a two-stage service matching algorithm.In order to tackle the QoS dynamic changing characteristics,through QoS agent monitoring and recording QoS values feedback by services in the past,the algorithm synthetically calculates the service QoS values.The paper presents the attenuation factor of QoS record weights with time and describes the algorithm.Experiment results show that the method is feasible. |
