Abstract

PURPOSE:To estimate a more accurate fault effecting range with a simple system by adopting the system that an actual fault effecting range in the case of occurrence of the fault is accumulated as fault history information. CONSTITUTION:A fault information detection section 50 detects a fault in the case of the occurrence of a fault and sends the state information as to the fault to a fault case estimating section 60. The fault cause estimating section 60 estimates a cause to a fault from the state information as to the fault and network constitution information stored in a network constitution information file 80. A network fault history file 90 stores the past actual fault effect range information to a cause to a network fault as the fault history information. A fault effecting range estimating section 70 retrieves whether or not the fault history information as to the fault cause exists in the file 90 and outputs the fault history information corresponding to the fault cause to an output device 30 when the fault exists. Moreover, the actual fault effecting range information inputted from an input device 40 in the occurrence of the fault is stored to the file 90.

The network failure assumption file 91 is a file that stores previously assumed failure causes and corresponding failure influence ranges.

When a failure occurs, the failure cause estimation unit 60 estimates the cause of the failure, and the failure influence range estimation unit 70 searches for failure influence range information corresponding to the failure cause.

The range affected by the failure is estimated by outputting the information.

[Problems to be Solved by the Invention] Conventionally, as information for estimating the range of failure influence, a method has been adopted in which information on the range of failure influence that is assumed to correspond to the assumed cause is prepared in advance.

Therefore, it is necessary to prepare in advance the failure influence range corresponding to various causes of failure in the network, which requires two complicated operations. Furthermore, it is difficult to assume accurate information about the range affected by a failure. Particularly, when a plurality of data processing devices and terminal stations are connected through a switching network, it is difficult to determine in advance the extent of a failure.

An object of the present invention is to make it possible to more accurately estimate the range affected by a failure using a simple method.

[Means to solve the problem]

FIG. 1 shows a basic configuration diagram of the present invention.

In the figure, 10 is an input/output control unit, 20 is an operation information collection unit, 30 is an output device, 40 is an input device, 50 is a failure information detection unit, 60 is a failure cause estimation unit, 70 is a failure influence range estimation unit, Reference numeral 80 indicates a network configuration information file, and reference numeral 90 indicates a network failure history file.

The fault information detection unit 50 detects whether a fault has occurred based on information sent from the network, and sends status information regarding the fault to the fault cause estimation unit 60 when a fault occurs.

The failure cause estimating unit 60 estimates the cause of the failure from the status information regarding the failure and the network configuration information stored in the network configuration information file 80.

The network failure history file 90 stores past actual failure influence range information regarding the causes of network failures as failure history information.

The failure influence range estimating unit 70 searches the network failure history file 90 for failure history information regarding the estimated cause of the failure, and if it exists, takes action to deal with the cause of the failure. The failure history information is output to the output device 30.

Further, the failure influence range estimating unit 70 stores actual failure influence range information input from the input device 40 when the failure occurs in the network failure history file 90.

[Effect]

When a failure occurs, the failure information detection unit 50 detects the occurrence of the failure and sends the failure status information to the failure cause estimation unit 60, so that the failure cause estimation unit 60 uses the failure status information and network configuration information to determine the failure status. Estimate the cause of the failure. The fault influence range estimating unit 70 searches the network fault history file 90 for fault history information regarding the estimated cause of the fault, and if it exists, searches for fault history information corresponding to the fault cause. By outputting to the output device 30, the range affected by the failure is estimated.

In addition, the actual failure influence range information that is input when the failure occurs is stored in the network failure history file 90 for future use.

(Example] FIG. 2 represents an embodiment of the invention.

The history search processing unit 72 searches whether or not failure history information corresponding to the cause of the failure estimated by the failure cause estimation unit 60 exists in the network failure history file 90.
If it exists, past actual failure influence range information corresponding to the cause of the failure is sent to the display processing unit 71.

The display processing unit 71 performs a process of displaying the past failure influence range on the display 30 as an estimated influence range.

Processing is performed to store the history information corresponding to the cause estimated by the failure cause estimation unit 60 into the network failure history file 90, which is input from the failure cause estimation unit 60 and the actual influence range of the failure.

For example, assume that the cause of the failure is estimated to be cause a2. The history search processing unit 72 searches whether or not history information corresponding to cause a2 exists in the network failure history file 90, and determines whether, for example, the range affected by cause a2 is X2. .

If X2□+
Processing is performed to output the fact that it is estimated to be 23×24. Here, if the actual range of influence due to the failure is, for example,
21. X 22. X 23+ X 24.
Suppose that it turns out to be X 25, and that fact is input.

The history creation processing unit 73 determines X2++ xZZ+ X23+ X24+ regarding the history information corresponding to cause a2.
Store X25.
