Network management system using model based intelligence

摘要

A method for isolating a network fault using a network management system, comprises the steps of: when contact between the network management system and a first network device is lost, setting a fault status for the first network device; determining the fault status of all network devices adjacent to the first network device; when the fault status of each network device adjacent the first network device is set, suppressing the fault status of the first network device; and when the fault status of at least one network device adjacent to the first network device is not set, maintaining the fault status of the first network device.
