Fault Management of Computer Networks based on Probe Station and Probe Set Selection

Fault diagnosis is a central aspect of network fault management. Since faults are unavoidable in communication systems, their quick detection and isolation is essential for the robustness, reliability, and accessibility of a system. In large and complex communication networks, automating fault diagnosis is critical. Traditionally, fault localization has been performed manually by experts but, as systems grew larger and more complex, automated fault localization techniques became important. Probing technique for fault localization involves placement of probe stations which affects the diagnosis capability of the probes sent by the probe stations and the overhead of instrumentation. In this paper we discussed a novel integrated approach of probe station and probe set selection for fault localization which outperforms the independent fault localization approaches. Keywords—active probing, fault detection, fault localization, probe set, probe station selection.
