As shown in FIG. 8, the performance information analysis method according to an embodiment of the present invention is performed by the performance information analysis system 200 receiving a time setting for collecting performance data from an operator.

The performance information analysis system 200 is set by the operator by connecting to the optical transmission device 110, the multiplexing device 120, the digital circuit switching device 130 and the wavelength division transmission device 140 constituting the transmission network according to the set time.

There is an advantage.

Next, the detailed method of the performance information analysis method will be described in detail for each step.

9 is a flowchart illustrating in detail a method of collecting performance information according to an exemplary embodiment of the present invention.

As shown in FIG. 9, the method for collecting performance information according to an embodiment of the present invention is performed by setting a performance collection environment in the performance information analysis system 200 such that an operator starts performance collection at a specific time.

The performance information collection unit 230 of the performance information analysis system 200 starts collecting performance information of the transmission network device 100 according to the performance collection environment setting (S100).

As performance information collection starts, the performance information management module 232 of the performance information collecting unit 230 establishes a sequential connection to the plurality of servers 233, 234, 235, and 236 in the accommodation layer illustrated in FIG. 5. It performs (S102).

In addition, the performance information management module 232 transmits to the plurality of servers 233, 234, 235, and 236 using a command such as "AGENT-LIST" and is currently connected to the servers 233, 234, 235, and 236. The list of devices 100 is requested (S104).

When the performance information management module 232 receives the requested list from the plurality of servers 233, 234, 235, and 236, the servers 233, 234, 235, and 236 may use a command such as "CONN-STAT". Request the connection state of each of the transmission network apparatus 100 connected to (S106), and checks whether the received connection state is smooth according to the request (S108).

As a result of checking in step S108, if the connection state is not smooth, the performance collection state of the transmission network apparatus 100 is failed and stored in the performance database 210 (S110).

As a result of checking in step S108, when the connection state is smooth, the performance information management module 232 uses the same command as "RTRV-FAC" to shape the lower components installed in each of the transmission network apparatus 100. FIG. A plurality of servers 233, 234, 235, and 236 are requested to obtain information (S112).

When the performance information management module 232 receives the shape information from the plurality of servers 233, 234, 235, and 236, the performance information management module 232 analyzes the details and stores the details in the performance database 210 (S114 and S116).

Here, the performance information management module 232 transmits the performance information for each shape information of the corresponding transmission network apparatus 100 to a plurality of servers 233 and 234 using a command such as "RTRV-PM" for an item related to performance. 235, 236) (S118). In this case, in order to collect the 15-minute performance data and the daily performance data, which are the basic units of performance information collection, respectively, the request is performed only for a predetermined time of 15 minutes or 1 day. Here, the 15-minute performance data represents a cumulative value of the performance values generated during the 15 minutes before the collection, and the daily performance data represents a cumulative value of the performance values generated during the day before the collection.

In this case, the 15-minute performance data can be collected 96 times a day, but collected six times a day, that is every four hours, so as not to degrade the capacity of the performance database 210 and the performance of the entire system, the performance value is Use the average of these four performance values.

 When the performance information management module 232 receives performance information for each transmission network device 100, the performance information management module 232 converts the performance information into a common message format (shown in FIG. 6) to be used for filtering and analyzing various performance information. Stored in (S120, S122).

Next, a process of extracting effective performance data, which is actual pure performance data, based on the collected performance information will be described in detail.

10 is a flowchart illustrating a method of extracting effective performance data according to an embodiment of the present invention.

As shown in FIG. 10, the method for extracting effective performance data according to an exemplary embodiment of the present invention is based on the performance information collected through the process of FIG. 9 by the performance information filtering unit 240 of the performance information analysis system 200. This is a process of extracting effective performance data based on construction information, broadcast information, test information, and alarm information stored in the database 220 shown in FIG.

The performance information collected in the method for collecting performance information shown in FIG. 9 may be generated by an alarm derived by another device because the transmission network is connected to two or more transmission network devices 500 and 510 as shown in FIG. It is not suitable for use as basic data for performance analysis because it may be generated by the construction of the track or device constituting the system. The same applies to the performance test affected by the circuit test and the one-way broadcasting line for constructing the customer service line. To this end, the alarm correlation is first examined with the information (including construction information, broadcast information, test information, and alarm information) collected in the database 220 shown in FIG. 4.

The performance information filtering unit 240 reads the collected performance information stored in the performance database 210 (S200).

In this case, the performance information filtering unit 240 may directly receive the performance information collected from the performance information collecting unit 230 and extract valid performance data.

The performance information filtering unit 240 reads the alarm information stored in the database 220, compares the occurrence point of the alarm with the collection point of the performance information, compares the occurrence time of the alarm with the performance collection time, and collects a specific time before collection. Analyzes and determines the alarm-related degree according to whether there is an alarm occurred during (S202).

As a result of the determination in S202, if there is an association in both of the two elements, it is processed as unnecessary data (S212).

As a result of the determination in S202, if there is no association in at least one element, the performance information filtering unit 240 reads the broadcast information stored in the database 220, and receives the device side of the device unit due to the unidirectional characteristic of the general airwave broadcasting. In operation S204, an analysis related to the broadcast relatedness according to whether or not the alert is generated and derived is performance information.

As a result of the determination in S204, if it is determined that the information is derived by broadcasting, the process is processed as unnecessary data (S212).

If it is determined that the information is derived by broadcasting, the performance information filtering unit 240 reads the test information stored in the database 220, and the operator newly establishes a line at the request of the customer. Analyzing and determining the circuit test-related degree according to whether or not the performance information generated by installing or inspecting the abnormality of the existing line (S206).

As a result of the determination in S206, if it is determined that the information is generated by the line test, it is processed as unnecessary data (S212).

As a result of the determination in S206, when it is determined that the information is not generated by the line test, the performance information filtering unit 240 analyzes and determines the construction related degree according to whether the performance information is derived by the construction of the line or the device. (S208).

As a result of the determination in S208, if it is determined that the information is derived by a specific construction, it is processed as unnecessary data (S212).

As a result of the determination of S208, when it is determined that the information is not derived by a specific construction, the corresponding performance information is stored in the performance database 210 (S210). At this time, the stored corresponding performance information becomes effective performance data.

At this time, the alarm information, broadcast information, line information, and construction information of each stage are received and stored from each operating station or stored by an administrator.

The performance information filtering unit 240 extracts valid performance data based on construction information, broadcast information, test information, and alarm information stored in the database 220 from the collected performance information, and stores the effective performance data in the performance database 210. In addition, the performance information filtering unit 240 may directly provide the collected performance information to the performance information analysis unit 250 of the next stage.

Next, a process of selecting a failure level by analyzing the effective performance data extracted by the performance information filtering unit 240 by the performance information analyzer of the performance information analysis system illustrated in FIG. 4 will be described in detail.

11 is a flowchart illustrating in detail a method of analyzing performance information according to an exemplary embodiment of the present invention.

As shown in FIG. 11, in the performance information analysis method according to the embodiment of the present invention, the performance information analysis unit 250 of the performance information analysis system 200 illustrated in FIG. 4 is performed by the performance information filtering unit 240. The extracted valid performance data is retrieved from the performance database 210.

In this case, the performance information analyzer 250 may directly receive effective performance data extracted from the performance information filter 240 to generate performance analysis information.

The performance information analysis unit 250 searches for the effective performance data stored in the performance database 210 for each performance location (location where abnormal performance data occurs) and performs the following operation for each individual record (S300).

The performance information analysis unit 250 first checks whether or not the abnormality record occurs three consecutive days in the same place (S302).

As a result of the check in step S302, if the abnormal record occurs three days in a row at the same location, the failure level is indicated as MJ (Major) grade that requires attention as the probability of failure in the near future is very high (S308).

As a result of the checking in step S302, if the abnormal performance record does not occur more than three consecutive days at the same location, it is checked whether the abnormality of the performance data for 15 minutes and one day occurs at the same time, and extracts an object that does not cause the performance degradation (S304). ).

If the abnormality of the performance data does not occur at the same time as a result of the check in step S304, the same process is performed on the next record (S300). At this time, since the record in which the abnormality of the performance data does not occur at the same time is the effective performance data in which the performance degradation does not occur, the valid performance data in which the performance degradation occurs is extracted by checking the next valid performance data for the performance abnormality.

As a result of the inspection of step S304, if abnormality of the performance data occurs at the same time, the failure level is indicated by the MN (Minor) grade that requires the operator's attention (S306).

The performance information analysis unit 250 analyzes the location where the performance record is generated and the customer facility / line information (S310), and determines whether there is a customer service line in use at the performance location according to the analysis (S312). At this time, it is assumed that the information on the customer service line being used for the performance location is received from the plurality of servers in the reception layer shown in FIG. 5 and stored in the performance database.

As a result of the determination in S312, if the customer service line in use exists, the corresponding line name is added to the performance slip to generate performance analysis information (S312, S316), and the generated performance analysis information is generated in the performance database 210. Save it.

In this case, the performance analysis information is effective performance data in which a failure level and a line name are displayed, and becomes performance information of a corresponding transmission network apparatus including the failure level and a line name.

As a result of the determination of S312, if there is no customer service line in use, performance analysis information is generated (S316), and the generated performance analysis information is stored in the performance database 210. At this time, the performance analysis information is valid performance data in which the failure level is indicated, and the line name is not displayed.

12 is a flowchart illustrating a method of issuing a performance slip according to an embodiment of the present invention.

The performance analysis information generated by the search is performed in the performance database 210.

In this case, the performance slip issuing and processing unit 260 may receive performance analysis information directly from the performance information analyzing unit 250 and perform performance slip publication.

The performance document issuing and processing unit 260 retrieves the performance analysis information and generates a unique performance document number by concatenating the 8-digit performance date and time of occurrence with the 5-digit serial number (eg, 20020809-00001) (S400). . In addition, a performance document including the performance analysis information and the performance document number is generated.

The performance document issuing and processing unit 260 delivers the generated performance document details to the relevant operator station, or searches for relevant local information via the system in which the abnormality has occurred in order to use it in the performance document processing authority check of the operator (S402). ).

Then, the performance slip issuing and processing unit 260, if there is a service line in the position where the performance slip occurs, retrieves the circuit configuration details such as the device and the upper and lower ports constituting it (S404), and the information Collect all of the performance document details in one text is generated and stored in the performance database (210) (S406).

The performance slip issuance and processing unit 260 issues a single slip to the local area related to the details of the performance slip (S408).

Subsequently, when the operator of the operating station related to the performance slip checks the details and performs a document closing action detailing the details of the action taken by testing the unit or identifying the cause (S410), the performance slip is issued and The processing unit 260 closes the performance document according to the closing document action (S412).

These measures can be managed as a single standard operating procedure and can be used as a basis for prompt action and prevention when the same case occurs next time.

In the above, the performance information analysis method of the performance information analysis system has been described in detail for each step.

Through the performance information analysis method, the performance information analysis system provides a performance slip according to the performance degradation of the transmission network device to a corresponding operating station (corresponding operating station of the transmission network device according to the performance analysis information), thereby causing a large obstacle that may occur in the transmission network.
