Most existed fault detector(FD) schemes didn't automatically adjust their detection service parameters for the dynamic network conditions,thus they couldn't be used for actual application.This paper explored FD properties with relation to the fault-tolerant cloud computing networks,and proposed a general self-tuning failure detection method in the fault-tolerant cloud computing networks.Based on the above general method,this paper proposed an automatic self-tuning failure detector(SFD) to optimize the existed FDs and explored the implementation of SFD.Finally,it comparatively evaluated the proposed failure detection scheme and existed schemes by extensive experiments in seven representative wide area network(WAN) cases.The experimental results show the properties of the different FDs,and demonstrate that the proposed scheme can adaptively detecte the fault to obtain corresponding services and satisfy user requirements,while maintaining good performance.
