JPH03166848A - Method and device for controlling exchange processor fault state - Google Patents

Abstract

PURPOSE:To reduce stored fault information and to easily find the trouble state by providing a network controller consisting of a fault information generation part, a fault information control part, and a fault state control part. CONSTITUTION:If a fault occurs, exchange processors 1-3 generate and send alarm information to the network controller 4 through the processor 3. The controller 4 generates fault information on the sending exchange processor, an in-processor detailed position, and the occurrence/recover discrimination of the fault from the alarm information and passes it to a fault information control part 42. The control part 42 registers the information in a data base file 5 when the occurrence/recovery discrimination of the fault of the fault information indicates 'fault occurrence' and deletes the fault information from the file 5 when the discrimination indicates 'fault recovery'. Then a fault state control part 43 finds the fault states of the processors 1-3 from the fault information registered in the file 5. Consequently, the amount of stored information becomes small and the fault information can be found easily and speedily by the processors.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

The switching device failure state management device shown in FIG. 1 includes switching processing devices 1 to 3, a network management device 4, and a database file 5.

Further, the network management device 4 includes a failure information creation section 4.
1, a fault information management section 42, and a fault state management section 43.

Such a switching processing device failure state management device constitutes a network system including the switching processing devices 1.2.3 and a network management system 4 that centrally manages these fault states.

The exchange processing devices M1 to M3 issue alarm information when a failure occurs. The issued alarm information is transmitted from the exchange processing device 3 to the network management device 4.

When the network management device 4 receives the alarm information issued by the exchange processing device 1, 2.3, the fault information creation unit 41 uses the alarm information to identify the issuing exchange processing device, the detailed location within the device, and the occurrence/recovery of the failure. Create fault information consisting of the following and pass it to the fault information management section 42.

If the failure occurrence/recovery distinction in the failure information is "failure occurrence", the failure information management unit 42 registers the failure information in the database file 5. Further, if the fault occurrence/recovery distinction in the fault information is "failure recovery", the fault information having the same detailed location within the device as the source replacement processing device is deleted from the database file 5.

The fault state management unit 43 stores the fault states of the exchange processing devices 1, 2.3 in the database file 5.
Obtained from the failure information registered in .

The database file 5 stores fault information from the fault information management section 42.

Next, the operation of this switching device failure state management device will be explained.

When a failure occurs in, for example, the exchange processing device 1 of the network system, the exchange processing device 1 issues alarm information. The issued alarm information is transmitted to the network management device 4 via the exchange processing device 3.

When the network management device 4 receives the alarm information, the fault information creation unit 4l creates fault information T0 consisting of the issuing exchange processing device, the detailed location within the device, and the occurrence/recovery distinction of the fault based on the alarm information. Pass it to the management department 42. Since the failure information T0 is “failure occurrence”, the failure information management unit 42 stores the failure information T0 in the database file 5.
Register. Since the failure information To of the exchange processing device 1 is registered in the database file 5, the failure state management unit 43 sets the failure state of the exchange processing device 1 to “failure occurring”.

Next, when the fault in the exchange processing device 1 is recovered, alarm information is sent to the network management device 4. When the network management device 4 receives the alarm information, the fault information creation unit 41 creates fault information T, and the fault information management unit 42
give it to Since the fault information T, is "failure recovery", the fault information management unit 42 deletes from the database file 5 the fault information T0 having the same detailed location in the device as the source exchange processing device of the fault information T+. The fault state management unit 43 stores even one fault information of the exchange processing device l in the database file 5.
Since it is not registered in , the failure state of the exchange processing device 1 is set as "normal".

In this way, this embodiment provides network management for alarm information issued by the switching processing devices in a network system configured with a plurality of switching processing devices and a network management device that centrally manages the fault status of each switching processing device. means for receiving the alarm information in the device and creating fault information consisting of the issuer exchange processing device, detailed location within the device, fault occurrence/recovery distinction from this alarm information, and a network management device if a fault has occurred among this fault information. means for registering the fault information in a database file in the network management device, and if the fault is to be recovered from the fault information, the fault information having the same detailed location within the device as the issuer exchange processing device is deleted from the database file in the network management device; and the means to do so.

These means allow the network management device to manage the failure state of the switching device.

〔Effect of the invention〕

As explained above, the present invention receives alarm information issued from a switching processing device, creates fault information consisting of the issuing switching processing device, detailed location within the device, and fault occurrence/recovery distinction. If a fault has occurred, the fault information is registered, and if the fault is recovered, fault information whose detailed location within the device is the same as that of the issuer exchange processing device is deleted. This allows only the information that is currently in the fault to be managed, reducing the amount of information. This has the effect that fault information for each switching device can be easily obtained, and fault information can be obtained quickly.
