摘要
根据Web服务的特点,考虑服务依赖关联和检测的可靠性需求,提出一种基于服务依赖关联和可靠性需求的层次型失效检测体系构造算法,研究失效检测的动态适应机制,包括反馈式和预防式策略。仿真实验结果表明,该算法可以提高失效检测的准确性和适应性,避免了"伪失效"现象。
According to the character of Web service and in view of service dependent correlation and reliability requirement, a hierarchical failure detection architecture construction algorithm based on service dependent correlation and reliability requirement is presented. The dynamical adaptation mechanisms including reactive strategy and proactive strategy are studied. Simulation experimental results show this algorithm can improve the accuracy and adaptation of failure detection and avoid fake failure case.
