Fault detection and localization is a central element in the management of network failures. It allows inferring the exact failure of a network from all the observed symptoms. Because failures in network systems are inevitable, detection and diagnosis efficiency is important for the stability, coherence and performance of a communication system. In this paper, we propose a unified approach to diagnosing nodes faults in a computer network. In our approach, the problems of choosing probing stations and probes, classically separated, are solved jointly in order to obtain, with lower complexity, minimum sets of probes and probing stations capable of detecting and localizing any failed node. The optimality of our new method has been tested through the simulation of the network configuration.
