基于SOA的Web服务可靠性预测

Reliability Prediction Approach for Web Service Based on SOA

在SOA架构下,服务发现的准确率是影响服务可靠性的因素之一。为了提高Web服务可靠性的预测精度,分析服务发现的失效是非常关键的。首先分析Web服务发现过程中可能出现的失效因素,构建Web服务发现的可靠性模型,并在此基础上提出新的Web服务的可靠性预测方法。最后通过实验验证了Web服务发现阶段的失效对Web服务可靠性的影响,并通过实例说明了Web服务的新的可靠性预测方法。实验结果表明,新的可靠性预测方法更加适用于Web服务。

In SOA,the precision ration of service discovery is the key factor in predicting service reliability. To improve the prediction accuracy of reliability for Web services, it is important to analyze the failure of service discovery. In this paper, firstly, the failure of service discovery was described and a discovery reliability model was built. Then, a new ap- proach for predicting services reliability was proposed based on the discovery reliability. Lastly, an experiment was con- ducted and the influence of service discovery on service reliability was analyzed. The experimental results show that the new reliability approach is more appropriate for Web services.
