Fault-tolerant processing technology is important to improve the reliability of networked manufacturing resources configuration system and the availability of resources, this paper introduces the common fault modes in manufacturing resources configuration system, the three key technologies in fault-tolerant processing are analyzed, such as failure detection, log management and failure recovery. The failure detectors with three-tier topology is designed, and log management framework met fault-tolerant requirements is proposed. Finally, according to the different forms of failur, retrying the existing configuration, replacing the service of failure resource and resources re-configuration are conducted for on-line fault-tolerant proecsing of the resources configuration.
