| 摘 要： | 随着Web Service技术的广泛应用，Qos成为一个非常重要的问题．以服务响应时间为Qos参数，验证了一种基于Web Service的分级QoS方法，提出了目标时间预设模型，并针对优化问题提出一种基于动态规划的解决方法，并实现了原型系统．实验数据表明这种方法有效地控制了负载平衡，实现了服务分级．

| Abstract: | With the development of web service applications, QoS becomes a severe problem. By using the average response time as the performance metric, a way about web services differentiated QoS is verified and then a method to model target response time is proposed. Meanwhile, an efficient method is proposed to solve dynamic programming questions. A prototype system is designed and implemented in the web service runtime environment. Experimental results show that this method is effective to control workload balance and provide web service differentiation. |
