摘要
针对Web服务组合环境对失效检测方法进行研究,设计主从式失效检测器和失效检测算法并对其进行分析,为Web服务组合监测提供有效的手段,实验模拟表明,该算法能有效降低错误率,提高系统可用性。
The paper researches the failure detection methods based on the Web service composition, designs the primary-slave failure detector, analyses a failure detection algorithm, and then provides effective means to Web service composition monitoring. The experimental simulation show that this algorithm can effectively decrease the error and improve, the system availability.
