Abstract:

Current work on fault detection wastes lots of probes to perform the detection process, and the work on fault localization has either high computation complexity or low diagnostic accuracy. To address the above problems, The probe selection for fault detection (PSFD) algorithm and integrated fault localization (IFL) algorithm are proposed. PSFD can detect the faults in the network with less probes and time, and IFL can perform fault localization much faster with higher accuracy. Performances of the two algorithms are validated by the experiment results.

Key words: fault management, active probing, fault detection, fault localization
