A network fault detection system includes a parameter extractor and a fault classifier. The extractor extracts a parameter value of a parameter for use in a classification feature vector from a packet received from a network. The parameter value relates to at least one of a first value for a first parameter associated with loss of packets, a second value for a second parameter associated with jitter among packets, and a third value for a third parameter associated with a characteristic of the occurrence of the loss of packets. The classifier determines whether or not a fault has occurred in the network and classifies the fault by type, based on numerical conditions and the parameter value.
