Network fault diagnosis belongs to the core of network fault management and plays an important role in improving network reliability and stability. Improve network diagnosis ability, can reduce network trouble repair time, reduce network operation cost. Intelligent network fault diagnosis is the main trend of the development of network diagnosis technology. The model of network fault propagation is analyzed and the fault propagation model of bipartite graph is used as the basis and improved. The Lagrange relaxation method is used to locate the fault. The design and implementation of service-oriented network fault management system OSFMS are deeply studied. The simulation results show that the system It can realize the intelligent diagnosis of network fault, improve the efficiency of network fault diagnosis and have good market value.
