Abstract

PURPOSE: A method for storing statistics data of an ATM(Asynchronous Transfer Mode) switch is provided to confirm the statistics data again after outputting the statistics data and use the stored statistics data as statistics analysis during a uniform duration by storing the statistics data collected by the ATM switch in a hard disk or a workstation of the ATM switch. CONSTITUTION: A current time is operated, and a file name is generated as a STATmm(dd)(hh) type(S10). The state of a hard disk is confirmed(S11). It is judged whether the state of the hard disk is abnormal(S12). If the state of the hard disk not is abnormal, a file name to be stored in a workstation is generated(S13). It is judged whether the generation operation succeeds(S14). A file is opened capable of reading and writing the file(S15). It is judged whether the opening operation fails(S16). If the opening operation succeeds, statistics data are stored in the hard disk of the workstation(S17).

Description

STATISTICS DATA STORE METHOD FOR ASYNCHRONOUS TRANSFER MODE EXCHANGE}

The present invention relates to a method for storing statistical data of an asynchronous transfer mode switch, and in particular, the operator periodically stores statistical data for a certain period of time in a manner in which the statistical data is not output and stored to the operator's terminal or printer, thereby saving the statistical data of the past. A method for storing statistical data of an asynchronous transfer mode exchange that can be analyzed.

In the related art, as shown in FIG. 1, the method for processing statistical data is determined after an error of an input parameter is determined by a statistical data management function (hereinafter referred to as SDMF) 10, which is a statistical data processing block. If not, the data collected by the operator is collected during the time input by the operator (usually within 1 hour) and the operator uses man-machine communication (hereinafter referred to as 'MMC'). Machine Interface, hereinafter referred to as 'HMI' (11) display window, or in the case of periodic statistics, the SDMF (10) collects statistical data every 15 minutes to the system message window at a certain time every day, every week The display is output through the printer 12 at the same time.

However, in the related art, since the statistical data is output only to an operator terminal or a printer on the HMI and then stored without being stored, there is a problem that it cannot be used again later.

Accordingly, the present invention has been devised to solve the above-mentioned conventional problems, and stores statistical data in a hard disk (HDD) of an exchanger or a workstation which is a terminal of an operator, or external storage such as a floppy disk. Its purpose is to provide a method for storing on a device.

1 is an exemplary view briefly showing a configuration for outputting statistical data of a conventional asynchronous transfer mode switch.

2 is an exemplary view briefly showing a configuration for applying the present invention.

3 is an exemplary view showing an operation flow of a method of storing statistical data of an asynchronous transfer mode exchange of the present invention.

Statistical data storage method of the asynchronous transfer mode switch of the present invention for achieving the above object, the workstation storage step of determining whether the current state can be stored in the workstation, and performs a predetermined storage operation accordingly; ;

A local hard disk storage step of determining whether a same file name as a file to be stored in the local hard disk of the exchanger exists if the result of the determination in the workstation storage step cannot be stored, and performing a predetermined storage operation accordingly;

When the data storage is normally completed in the local hard disk storage step, when the data can be stored in the workstation, it is characterized in that the resave step of performing a predetermined operation process for copying the stored data to the workstation .

Hereinafter, described in detail with reference to the accompanying drawings an embodiment according to the present invention.

2 is a schematic view showing a configuration for applying the present invention, as shown in the SDMF 10 is a processor performance data collection block (Statistics On Processor Function, SOPF) and fault, alarm data collection block (Statistics On Fault Function (SOFF) and Statistical Data On Block (Statistics On Call Function (SOCF)), which collects the data of each cycle (hourly, daily, weekly, monthly, etc.) to the workstation's hard disk 22. If the storage fails, it is stored in the local hard disk 21 in the exchange.

In addition, the contents stored in the hard disk store the necessary data among the collected raw (RAW) data. For example, the files stored every hour are STAT010101, STAT010102,... , STAT123123, and the file that is saved every day is STAT0101,…. , STAT1231, and the monthly saved files are STAT01,… Each file is stored in a text box and maintained for a specified period (usually one year).

When described in detail with reference to Figure 3 attached to the operation process according to an embodiment of the present invention configured as described above are as follows.

3 is an exemplary view showing an operation flow of a method of storing statistical data of an asynchronous transfer mode switch of the present invention. As shown in the drawing, first, after calculating a current time, a file name is created in a STATmm (dd) (hh) format. In operation S10 to S12, it is determined whether or not the abnormality is determined by checking the state of the hard disk 22, and if the abnormality is not abnormal, generating a file name to be stored in the workstation (confirms whether a file having the same name exists). If yes, delete it, and if not, create a new file) (S13 to S14).

If the determination result of step S14 succeeds, it is determined whether the operation of opening the file so that the file can be read and written has failed (S15 to S16). If the determination result of step S16 succeeds, the hard disk of the workstation ( 22) and ends (S17).

If data cannot be written to the workstation, the data is temporarily stored in the local hard disk 21 in the switchboard. First, if there is a file having the same name as a file to be stored in the hard disk 21, it is deleted. If there is no file of the same name, an operation of generating a file in the hard disk 21 is performed (S20 to S21).

If the operation fails in step S21, after generating the 'STAT' directory, and generates a file name to be stored in the local hard disk 21 (S23).

If the operation of the step S21 is successful, the operation of opening the file to read and write the file is performed (S22), stored in the local hard disk 21, and terminated (S27).

However, it is determined whether the operation of the step (S23) is successful (S26), and if successful, it is stored in the local hard disk 21 and ends (S27).

When the statistical data is normally stored in the local hard disk 21 of the switchboard, the data is moved to the hard disk 22 of the workstation. The state of the workstation is first waited for a predetermined time (for example, 5 minutes). If the normal state is executed to perform the operation to open the file to be stored (S30).

If the operation is successful, the data stored in the local hard disk 21 is stored in the hard disk 22 of the workstation and then terminated (S31 to S32). If the result of the determination is less than or equal to 1, the number of repetitions is increased by '1' and the process returns to the step S30 (S34).

If the save operation fails, if the link between workstations is normal while retrying for a predetermined time (for example, 10 times) at a predetermined time (for example, 5 minutes), the file of the hard disk 21 The hard disk 22 is moved.

In addition, the statistical data may be stored in an external storage device (not shown) such as a floppy disk instead of a hard disk (HDD) of an exchanger or a hard disk of a workstation that is an operator's terminal.

As described above, in the method of storing statistical data of the asynchronous transfer mode exchange of the present invention, the statistical data collected by the exchange is stored on the exchange's hard disk or workstation for a certain period of time, so that the statistical data can be checked again after output. Can be used as a statistical analysis for a certain period of time, thereby maximizing the efficient operation of the exchange.
