Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a failure alarm data collection device for a large-scale communication device, and more particularly to an ATM (Asyncron).
in a communication device that handles a huge number of paths (such as ous transfer mode) and the communication data processing unit is composed of a large number of packages, collects failure alarm data related to failures of those packages and path alarms. The present invention relates to a failure alarm data collection device for sending to a failure alarm management unit.

[0002]

2. Description of the Related Art Conventionally, in a large-scale communication device, there are a plurality of packages for processing communication data, and there is a package for collecting failure alarm data related to a failure in such a package or a warning of a path and managing the failure alarm. It exists independently and separately. The failure alarm management package constantly collects the failure alarm data from each package for processing communication data regardless of whether or not the data has changed.

[0003]

However, as the size of the communication device increases, the amount of data to be collected becomes huge and the time required for the collection increases. On the other hand, since failure alarm processing is required to be performed in real time, the time that can be spent for collection is limited. Therefore, even if the amount of data to be collected increases, the time required for collection must be increased. There was a problem that I could not do it.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a failure alarm data collection device for a communication device which shortens the time required to collect the failure alarm data.

[0005]

In order to achieve the above object, the communication data processing unit 1 according to the present invention, as shown in FIG.
All data transmission means 1a for transmitting all failure alarm data of the communication data processing unit 1 to the failure alarm management unit 2
And a change amount data transmission unit 1b provided in the communication data processing unit 1 for transmitting only a time change amount of the failure alarm data of the communication data processing unit 1 to the failure alarm management unit 2.
The latest data of the communication data processing unit 1 is provided in the failure alarm management unit 2 based on all the failure alarm data transmitted by the all data transmission unit 1a and the change data transmitted by the change data transmission unit 1b thereafter. There is provided the latest data reproducing means 2a for reproducing the failure alarm data of 1., and a failure alarm data collecting device for a communication device is provided.

Further, the failure alarm data collection device of the communication device is provided in the communication data processing unit 1 and transmits error confirmation data regarding all the latest failure alarm data of the communication data processing unit 1 to the failure alarm management unit 2. The latest failure alarm data reproduced by the latest data reproducing means 2a is communicated based on the error confirmation data transmitted by the error confirmation data transmitting means 1c and the error alarm management section 2 and transmitted by the error confirmation data transmitting means 1c. Consistency confirming means 2 for confirming that the latest fault alarm data of the data processing unit 1 is in agreement.
and b.

[0007]

[Function] Usually, the failure of the circuit in the package rarely occurs, and therefore, the failure data of the failure alarm data does not change much in terms of time. By collecting only those items that have occurred, the time required to collect the failure alarm data is shortened.

That is, in the above-mentioned structure, first, the all-data transmitting means 1a transmits all the failure warning data of the communication data processing section 1 to the failure warning management section 2. After that, the change amount data transmitting unit 1b transmits only the change amount over time of the failure alarm data of the communication data processing unit 1 to the failure alarm management unit 2.

In the failure alarm management section 2, the latest data reproducing means 2a is operated based on all the failure alarm data transmitted by the all data transmitting means 1a and the change data transmitted by the change data transmitting means 1b thereafter. The latest failure alarm data of the communication data processing unit 1 is reproduced.

As described above, basically, all the failure alarm data are transmitted only at the beginning, and thereafter, only the variation data is transmitted. Therefore, if the variation is small, the communication data processing unit 1
The amount of data transmitted from the device to the failure alarm management unit 2 is greatly reduced, and the time required to collect the failure alarm data is shortened.

Further, the error confirmation data transmitting means 1c transmits the error confirmation data relating to all the latest failure alarm data of the communication data processing unit 1 to the failure alarm management unit 2. Based on the error confirmation data transmitted by the error confirmation data transmission unit 1c, the coincidence confirmation unit 2b of the failure alarm management unit 2
Confirms that the latest failure alarm data reproduced by the latest data reproducing means 2a and the latest failure alarm data of the communication data processing unit 1 match. That is,
In the case of transmitting only the variation, when noise or the like is mixed in the transmission signal, the failure alarm data reproduced by the latest data reproducing means 2a thereafter does not match the latest failure alarm data of the communication data processing unit 1. In order to prevent this, the error confirmation data is used to confirm that the latest failure warning data reproduced by the latest data reproducing means 2a matches the latest failure warning data of the communication data processing unit 1.

That is, for the communication alarms a, b, ..., For example, BIP (Bit Interleave Parity) calculation is performed to create an error detection code, and the error detection code is added to the multiplexed signal so that it can be output as alarm data.

Similarly, the failure information collection block 22 comprises a data multiplexing unit 22a and an error detection code adding unit 22b. The data multiplexing unit 22a multiplexes the failure information, ... And the error detection code addition unit 22b adds an error detection code. That is, for the failure information, ..., For example, BIP operation is performed to create an error detection code, which is added to the multiplexed signal so that it can be output as failure data.

The alarm data stored in the alarm / fault information storage memory 23g is all communication alarms.

The error detection code adding section 23e creates an error detection code by, for example, performing BIP operation on all the alarm data stored in the alarm / fault information storage memory 23g. When the communication control unit 23h receives a transfer request for all data from the failure / alarm management processing package 13, the control unit 23c causes the alarm / failure information storage memory 23g.
All of the alarm data stored in is extracted, the error detection code is added to them, and the communication alarm data is transmitted to the failure / alarm management processing package 13. On the other hand, when the communication control unit 23h receives a change data transfer request from the failure / alarm management processing package 13, the control unit 23h
In c, the alarm data sent each time a data output request is compared with the data sent last time, only the communication alarms that have changed are taken out, error detection codes are added to them, and failure / alarm management is performed as communication alarm data.

FIG. 5 shows a fault / alarm management processing package 1.
3 is a block diagram showing the internal configuration of FIG. In the figure, the failure / warning data processing block 13a includes transfer data expansion processing units 25 and 26, a communication warning data memory 27, a failure information data memory 28, and error detection circuits 29 and 30.
It is composed of a data collection controller 31 and a memory controller 32. First, the transfer data expansion processing unit 25 receives the communication data processing packages (A to X) 1 from the data collection control unit 31.
In accordance with a transfer request for all data sent to 1 to 12 or a transfer request for changed data, the communication alarm data sent from each communication data processing package (A to X) 11 to 12 is received and expanded for each package. Then, they are respectively stored in the corresponding address positions of the communication alarm data memory 27. The communication warning data stored in the communication warning data memory 27 is originally the warning / fault information storage memory 2
It should be consistent with the alarm data stored in 3g. The error detection code sent together is stored in the check data area of the communication alarm data memory 27. The writing control to the communication alarm data memory 27 is performed by the memory control unit 32.

The error detection circuit 29 detects all the communication alarm data stored in the communication alarm data memory 27.
For example, BIP calculation is performed to create an error detection code. Then, the error detection circuit 29 compares the created error detection code with the error detection code stored in the check data area of the communication alarm data memory 27, and if they match, the communication alarm data memory 27. It is assumed that the communication alarm data stored in the communication alarm data is the same as the alarm data stored in the alarm / failure information storage memory 23g. It is output to a CPU processing unit (not shown) of the alarm management processing package 13. On the other hand, if the error detection codes do not match, the communication alarm data stored in the communication alarm data memory 27 is stored in the alarm / fault information storage memory 2
Since the alarm data is not the same as the alarm data stored in 3g, the memory control unit 32 is activated and the data collection control unit 31 outputs a transfer request for all data to the communication control unit 23h. The data collection control unit 31 outputs a transfer request for all data to the communication control unit 23h under the control of the memory control unit 32 as described above, and periodically outputs a transfer request for changed data to the communication control unit 23h. .

Similarly, the transfer data expansion processing unit 26 follows a transfer request for all data or a change data transfer request sent from the data collection control unit 31 to each communication data processing package (A to X) 11 to 12. , The failure information data sent from each of the communication data processing packages (A to X) 11 to 12 is received, expanded for each package, and stored in the corresponding address positions of the failure information data memory 28. The failure information data stored in the failure information data memory 28 should originally match the failure data stored in the alarm / failure information storage memory 23g. Further, the error detection code sent together is stored in the check data area of the failure information data memory 28. The writing control to the failure information data memory 28 is performed by the memory control unit 32.

The error detection circuit 30 operates on all of the failure information data stored in the failure information data memory 28.
For example, BIP calculation is performed to create an error detection code. Then, the error detection circuit 30 compares the created error detection code with the error detection code stored in the check data area of the failure information data memory 28, and if they match, the failure information data memory 28. It is assumed that the failure information data stored in the failure information data is the same as the failure data stored in the alarm / failure information storage memory 23g, and the failure information data stored in the failure information data memory 28 is processed by a CPU that performs failure / alarm management. Output to department. On the other hand, if the error detection codes do not match, the failure information data memory 28
The fault information data stored in the alarm / fault information storage memory 23g is not the same as the fault data stored in the alarm / fault information storage memory 23g. Therefore, the memory control unit 32 is activated to transfer all the data from the data collection control unit 31. The request is output to the communication control unit 23h.

A failure / warning data collection method in the communication device having the above configuration will be described with reference to FIG. First,
In the communication data processing package (A) 11, failure information A-, A-, ... And communication alarms A-a, A-b, ... And check data A for these failure information and communication alarm
1 and A2 are created respectively. Check data A1,
A2 is an error detection code created by BIP calculation, for example, and is created for each of the failure information and the communication alarm. And the failure / alarm management processing package 1
When there is a request for transfer of all data from 3, all the failure information and communication alarm are transmitted to the failure / alarm management processing package 13 together with the check data A1 and A2. On the other hand, when a change data transfer request is issued, the failure information and communication alarm are compared with the failure information and communication alarm from the previous transfer request and the failure information and communication alarm from the current transfer request. Only the changing failure information and the communication alarm are retrieved, and the failure / alarm management processing package 1 together with the check data A1 and A2.
Sent to 3. Communication data processing package (A) 11
The packet communication using the LAN, for example, is applied to the communication with the failure / alarm management processing package 13. The same operation is performed in other communication data processing packages (B to X) and the like.

The data format of the transmitted failure information and communication alarm is shown in FIG. That is, in the case of failure information and communication alarm, the "transfer content" column indicates the target package and its failure content or alarm type.
Also, in the case of check data, the type of check data is described, and in the case of “failure / alarm content” column, in the case of failure information and communication alarm, the occurrence or recovery of failure or alarm, and the check data In some cases, check data created by BIP calculation or the like is described.

Returning to FIG. 6, the failure / alarm management processing package 13 reproduces the failure / alarm management data for each communication data processing package. That is, in the case of failure information and communication alarm, the "content" column describes the package to be sent and its failure content or the type of alarm, and the "status" column describes the occurrence or recovery of the failure or alarm. . When these changes are sent, only those changes are updated, so that they should be the same as the fault information and communication alarm that originally occurred in the communication data processing package. However, the transmission channels may not be the same due to the inclusion of noise or the like. In order to detect such a situation, the failure / alarm management processing package 13
Creates check data for the data stored in the failure / alarm management data by BIP calculation separately for the failure data and the alarm data, and compares these with the sent check data A1, A2, respectively. As a result, if they match, it is determined that the failure information or communication alarm reproduced by the failure / alarm management processing package 13 is the same as the failure information or communication alarm generated in the corresponding communication data processing package. be able to.

Therefore, by transmitting all the failure alarm data only at the beginning and then transmitting only the change amount data, if the change amount is small, it is transmitted from the communication data processing package to the failure / alarm management processing package 13. The amount of data is greatly reduced, and the time required to collect failure / alarm data is shortened.

FIG. 8 is a flowchart showing the operation at the time of starting up a certain communication data processing package. By this operation, the initial transmission for all the failure data or alarm data is performed. Hereinafter, description will be given along the steps of the figure.

[S1] The communication data processing package is reset. [S2] Data transfer is started from the communication data processing package to the failure / alarm management processing package 13.

[S3] The designated number for designating the address of the alarm / fault information storage memory 23g of the fault / alarm collection block 11b is set to zero. [S4] The data of the alarm / fault information storage memory 23g having the same address as the designated number is stored in the fault / alarm management processing package 1
Transfer to 3.

[S5] Alarm / fault information storage memory 23g

If completed, the process proceeds to step S7, and if not completed, the process proceeds to step S6.

[S6] The designated number for designating the address is advanced by one. [S7] The check data (error detection code) in the alarm / fault information storage memory 23g is transferred to the fault / alarm management processing package 13.

[S8] Failure / Alarm Management Processing Package 1
In 3, the check data sent is compared with the check data created for the reproduced data. If they match, it means that all of the failure data or alarm data has been sent without fail. . If they do not match,
The process returns to step S3 and the transmission is performed again.

In the above description, the failure data and the alarm data are not distinguished, but in reality, this flowchart is executed for each of the failure data and the alarm data.
FIG. 9 is a flowchart showing the operation of each communication data processing package and the failure / alarm management processing package 13 for transmitting the change failure data or the alarm data. Hereinafter, description will be given along the steps of the figure.

[S11] The transfer of the communication data processing package A is started. [S12] It is determined whether or not the failure data or alarm data in the alarm / failure information storage memory 23g of the communication data processing package A has changed compared to the previous transfer.
If there is a change, the process proceeds to step S13, and if there is no change, the process proceeds to step S15.

[S13] Only changed data is transferred to the failure / alarm management processing package 13. [S14] If all the changed data has been transferred, the process proceeds to step S15, and if there are still data, the process proceeds to step S15.
Return to 13.

[S15] The failure data in the alarm / failure information storage memory 23g of the communication data processing package A or the check data (error detection code) for the alarm data is transferred to the failure / alarm management processing package 13.

[S16] The failure / warning management processing package 13 compares the transferred check data with the check data (error detection code) created by itself. [S17] If the check data match each other, the process proceeds to step S19, and if they do not match, the process proceeds to step S18.

[S18] A transfer request for all data is generated,
All the failure data or alarm data in the alarm / failure information storage memory 23g of the communication data processing package A is transferred to the failure / alarm management processing package 13.

[S19] The failure data or the warning data in the warning / failure information storage memory 23g of the communication data processing package A is the failure / warning management processing package 13.
Since it is being played correctly, the transfer ends.

[S20] to [S21] Steps S11 to S11
The same processing as step S19 is executed for the communication data processing packages B to X. In the above description, the failure data and the alarm data were explained without distinction, but in reality,
This flowchart is executed for each of the failure data and the alarm data.

In the above embodiment, the check data is prepared separately for each of the failure data and the alarm data. However, the failure data and the alarm data are further divided into groups, and the check data is separated for each group. It may be prepared, and in this case, when there is a mismatch between the check data and all the data is transferred again, only the data within the group need be transferred, so that the transfer time can be further shortened. On the contrary, the failure data and the alarm data may be combined into one group and only one check data may be prepared. In this case,
The circuit configuration can be simplified. Furthermore, the present invention can be realized without check data, and in this case, the circuit configuration can be further simplified, but it is not possible to deal with the inclusion of noise or the like.

[0044]

As described above, in the present invention, only the fault alarm data that has changed is transferred in the normal operating state except when the apparatus is started up. The time required to collect the failure alarm data can be shortened as compared with the case where the data is always transferred.

Further, when the changed failure alarm data is transferred, by adding check data (error detection code) to all of the current failure alarm data on the transmitting side, it is reproduced by the failure alarm management unit. Even if a discrepancy occurs between the fault alarm data and the current fault alarm data on the transmitting side, it can be easily found, and therefore the risk of remaining discrepancy can be avoided.

Further, by dividing the failure alarm data into groups, if there is a discrepancy between the failure alarm data reproduced by the failure alarm management unit and the current failure alarm data on the transmitting side, all the data will be recorded. The time required for transfer can be shortened.
