Abstract: 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.

Key words: Web service, reliability, failure detection, adaptation
