Background technique

As shown in Figure 1, the telecommunication network usually adopts hierarchical management, in which the network management is divided into three layers: equipment, network element network management system, and integrated network management system. The specific interaction between the three layers is as follows: the data of the device is transmitted through an interface connected to the integrated network management system by the network element network management system, and the interface of the connection is called a northbound interface. The northbound interface is the interface that the device manufacturer or carrier accesses and manages the network, that is, the interface provided upward. The northbound interface is usually used for data reporting of the device network management. The reported data types include: warning, performance, assets, and configuration data. The northbound interface is mainly divided into: FTP (File transfer protocol), SNMP (Simple network management protocol), and CORBA (Common Object Request Broker Architecture); FTO is suitable for the reporting of single-line data, suitable for the transmission of big data; CORBA and SNMP interfaces support many functions, such as data, status query, control and configuration data of faults, topologies and resources.

The NE network management system can add devices or add new management methods, such as the new management mode: manage different devices through multiple device network management systems.

Embodiments of the invention

Embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

The embodiment of the present invention is directed to a new device or a new management mode in the network element network management system in the prior art, which may cause the interface of the integrated network management system to be incompatible, and generate a problem that the northbound file is easily interfered, and provide a method for generating a northbound file. , devices and systems.

First embodiment

As shown in FIG. 1 , a method for generating a northbound file according to an embodiment of the present invention is applied to a first network element network management, where the method for generating a northbound file includes:

Step 101: When the first time point is reached, if the first north file is not detected, create a lock file and create a first north file corresponding to the lock file, and set a flag of the lock file as a start flag, where A time point is when the first network element network controller prepares to generate an undetected first northbound file.

It should be noted that: the foregoing first time point includes a time point at which the first network element network controller starts to prepare to generate the first northbound file, and includes a preset time point for generating the first northbound file; generally, the first time point is followed by the user. The number of northbound file devices (network element network management) and user requirements are determined. Optionally, for the user's needs, generally between 21 pm and 5 am in the night, the device generates fewer northbound files, so there are fewer time points set at night. For generating a northbound file device, for example, if the number of northbound file devices is eight, the first time point set is 8:00 in the morning, and one time point is set corresponding to each hour, and other generated northbound files are started according to the set time point. device of.

In addition, the first network element network management may start the first preset time period, that is, the step 101 may include: when the first north time file is not detected, the first preset time period is reached when the first time point is reached. The lock file and the first northbound file corresponding to the lock file are created, and the flag of the lock file is set as a start flag, wherein the first time point is a time for the first network element network to generate the first northbound file. The first preset time period may be set according to the needs of the user or the industry; generally, the first preset time period may also be based on the length of time that the device normally generates the northbound file, or the length of time for each device to normally generate the northbound file. It is determined by the number of northbound file devices generated. For example, under normal circumstances, when the device generates the first northbound file for half an hour, the first preset time period may be set to 1 hour to 2 hours. If there are many devices that generate northbound files, for example, if the total number of four northbound file devices is 30 minutes, set the first preset time period to 40 minutes when the first northbound file is generated. To an hour. Of course, the above is merely an example and is not limited herein. The device for generating the northbound file may include a device that works all the time, and may also include a device that works according to a preset time period set by the user. The invention can be selected to work according to a preset time period, which can reduce the load of the device.

Also, the purpose of setting the flag of the lock file as the start flag is that it does not interfere with other processes or devices during the process of generating the first northbound file.

Step 102: Write the collected data into the first northbound file, and modify the flag of the lock file to a completion flag.

It should be noted that, as shown in FIG. 2, the collected data includes at least a network element 24 and a network element 25 managed by the first network element network management unit 23, and the corresponding network element subsystem collects data of the monitored equipment. The first northbound file is generated based on the data, and the integrated webmaster 21 collects the northbound file (the northbound file 22 includes the first northbound file).

Moreover, the purpose of the lock file is that the completion flag is: after the first north file is generated, it indicates that the device has no tasks, and can receive other devices to access or perform other tasks.

In the embodiment of the present invention, the first network element network management system uses the flag of the lock file as the start flag to start generating the first northbound file, and after generating the first northbound file, the start flag of the flag of the lock file is changed to the completion flag. In this way, the first northbound file can be stably outputted under the effective shielding of the first network element network management.

For the first embodiment of the present invention, it should be noted that the first northbound file generated by the foregoing may be stored locally in the first network element network management device or may be stored by other devices. Generally, it can be stored by other devices, which can reduce the load of the network element of the first network element. When other network element network tubes need to be used or added, the device directly obtains or reads the write location from other devices, thereby reducing the network element of the first network element. The load of the interaction process.

As shown in FIG. 3, if the first northbound file already exists in the first network element network management system, if the first northbound file is repeatedly generated, the burden of the first network element network management is increased, and the problem of executing the task error may occur. Therefore, the method for generating a northbound file in the embodiment of the present invention further includes:

Step 103: When the first northbound file is detected, if the flag of the lock file corresponding to the first northbound file is not detected, a flag of the lock file corresponding to the first northbound file is generated, and the generated identifier is set as a completion flag. If the lock file corresponding to the first northbound file is detected, but the flag of the lock file is the start identifier, the flag of the modified lock file is the completion flag.

In the embodiment of the present invention, by detecting whether there is a first northbound file in advance, when there is a first northbound file, it is detected whether there is a flag of the first northbound file that has been generated, and if the flag of the first northbound file is not generated, the lock is generated. The logo of the file and the flag of the modified lock file is the completion flag. The first northbound file will not be regenerated; if there is a flag for the first northbound file, the task is ended, thus avoiding repeated tasks.

As shown in FIG. 4 and FIG. 5, each time the integrated network management system can obtain only one northbound file, the new device or the new management mode may cause the interface of the integrated network management system to be incompatible. Therefore, the northbound file is generated in the embodiment of the present invention. The method also includes:

Step 104: Send the first northbound file to the preset device, and store the first northbound file by the preset device.

It should be noted that the preset device herein may include a computer, a virtual machine, or another type of server, and any terminal that can store the first northbound file belongs to the protection scope of the embodiment of the present invention, and is not exemplified herein.

Here, the first northbound file, that is, the first northbound file output, is a typical data output format. Usually the file output can be CSV (Comma-Separated Values, comma-separated values, the file stores the table data (number and text) in plain text), TXT (TXT is a text format that Microsoft attaches to the operating system, is the most common A file format, as early as the DOS era, a lot of applications, mainly text information, that is, text information, the current operating system is mostly saved using a program such as Notepad, most software can be viewed, such as Notepad, browser, etc. ), XML (Extensible Markup Language) or other formats. The northbound file can be located in the FTP (File Transfer Protocol) of the preset device or the specified directory of the hard disk. Northbound files have a fixed file or folder name. For example, generate asset information; the usual name is as follows: PORT_20150910.csv, the naming indicates the PORT (port) asset information obtained by the network element network management on September 10, 2015. The integrated network management system obtains all the data reported by the first network element network management system and/or the second network element network management system, and can perform unified data analysis on the entire network.

In the embodiment of the present invention, the northbound file (including the first northbound file and the second northbound file, that is, the collective name of all northbound files) and the lock file may generally be set according to the following rules:

The flag of the lock file is the rule name of the start flag: PORT_20150910_start.log

The lock file is marked with the rule name of the completion flag: PORT_20150910_finish.log

The first half of the file name of the lock file is the content of the north file name without the suffix. Start with a start flag, such as _start.log; at the end, change to the end flag, such as _finish.log.

Also, the logo of the lock file may be referred to as a start lock file, and the logo of the lock file may be referred to as a completion lock file. The start lock file and the completion lock file may only exist one during the entire implementation process. Generally, by changing the file name or deleting the reconstruction method, the completion of the lock file and the start lock file are unique during the execution of the task.

In the embodiment of the present invention, the first northbound file is stored in the preset device, and each of the other network element network management tubes that generate the northbound file also stores the generated northbound file in the preset device, so that the integrated network element can be from the preset device. The first northbound file is obtained directly. It does not need to consider the impact of new devices or new management methods on the integrated network element. It still uses the same northbound file format output as the original northbound file, and avoids the interface incompatibility problem of the integrated network management. Improve the efficiency of integrated network management to obtain northbound documents.

The embodiment of the invention further provides a computer storage medium, wherein the computer storage medium stores computer executable instructions, and the computer executable instructions are used to execute the method for generating the northbound file.

As shown in FIG. 6, the overall implementation process of creating a first northbound file by the first network element network management system in the embodiment of the present invention is as follows.

Step 601: The first network element network management checks whether the first northbound file exists. If the first northbound file exists, the process proceeds to 607. If the first northbound file does not exist, step 602 to step 606 are performed. If the first northbound file already exists, adding the first northbound file will fail. This reason is usually caused by modifying the network management time of the first network element to cause the task to run repeatedly. Or the time calculation of other network element network management is incorrect, and the first northbound file is generated in advance.

In step 602, a lock file is created, and the flag of the lock file is set as a start flag.

In step 603, a first northbound file is created.

Step 604, the data collected from the network element or the database is written into the first northbound file.

Step 605: After the collected data is written, the flag of the lock file is modified to a completion flag.

Step 606, completing the generation of the first northbound file.

Step 607, checking whether the lock file exists, if the lock file does not exist, executing 608; If the lock file exists, the data addition fails, and 609 is executed.

Step 608, creating a lock file; creating a lock file can prevent the subsequent network element network management from repeatedly adding data. Here, the subsequent network element network management includes other network element network tubes subsequent to the first network element network element.

In step 609, the task ends.

Second embodiment

As shown in FIG. 7, the method for generating a northbound file according to an embodiment of the present invention is applied to a second network element network management system, and the second network element network management system processes a first northbound file of the first network element network management.

Step 701: When the second time point is reached, if it is detected that the flag of the first northbound file corresponding to the lock file is a completion flag, the flag of the lock file is modified from the completion flag to a start flag;

In the embodiment of the present invention, the second time point is after the first time point, and the first time point is a time point at which the first network element network management generates the first northbound file in advance; in the embodiment of the present invention, the first network element network management The second network element network management system may be relative, and may be determined according to the sequence of processing the northbound files.

It should be noted that the second time point includes a time point at which the first network element network controller starts to prepare to generate the second northbound file, and the second time point is generally determined by the user according to the number of generating northbound file devices and user requirements. Optionally, for the user's needs, generally between 21 pm and 5 am in the night, the device generates fewer northbound files, so there are fewer time points set at night. For generating a northbound file device, for example, if the number of northbound file devices is eight, the second time point is set to 8:00 in the morning, and a time point is set corresponding to each hour, and other generated northbound files are started according to the set time point. device of.

In addition, the first network element network management system may start the second preset time period, that is, the step 701 may include: detecting the second northbound file corresponding lock file when the second preset time period is reached at the second time point. When the flag is the completion flag, the flag of the lock file is modified from the completion flag to the start flag, wherein the second time point is after the first time point, and the first time point is the time for the first network element network to generate the second north file. . The second preset time period can be set according to user or industrial needs. Generally, the second preset time period may be determined according to the length of time that the device normally generates the northbound file, or the number of times the northbound file is normally generated by each device. For example, under normal circumstances, when the device generates the second northbound file for half an hour, the second preset time period may be set to 1 hour to 2 hours. If there are many devices that generate northbound files, for example, if the total number of four northbound file devices is 30 minutes, set the second preset time period to 40 minutes when the second northbound file is generated. To an hour. Of course, the above is merely an example and is not limited herein. The device that generates the northbound file can always be in the working state, or can work according to the preset time period set by the user. The invention can be selected to work according to a preset time period, which can reduce the load of the device.

Step 702: Appending the collected data to the first northbound file to generate a second northbound file.

The second northbound file here is generated by additionally writing the collected data to the first northbound file, which is equivalent to adding the collected data to the file after the first northbound file. However, the northbound file may include a first northbound file and a second northbound file.

In addition, the second network element network management system can be used as the final network element network management system, or can be used as the intermediate network element network management system, and is the final network element network management system or the intermediate network element network management system, which are related to practical applications. As shown in FIG. 2, the second network element network management system is used as the final network element network management unit, and the collected data includes at least the network element 27 and the network element 28 managed by the final network element network management unit 26 (the network element network management unit including the final network element network management unit). The corresponding network element subsystem collects data of the monitored device. A second northbound file is generated based on the data (the northbound file 22 includes a second northbound file), and the integrated webmaster 21 collects the northbound file.

Step 703: Modify the flag of the generated lock file of the second northbound file to be a completion flag.

In the embodiment of the present invention, a second northbound file is formed by adding a first network element network management by the second network element network management, that is, a second northbound file is generated, and multiple network management systems generate a unified northbound interface output, and data is needed in the integrated network management system. When the second northbound file is directly obtained, the impact of the newly added device or the new management mode on the integrated network element is not considered, and the same northbound file format output as the original northbound file is still used, and the interface incompatibility problem of the integrated network management is also avoided. , improve the efficiency of the integrated network management to obtain northbound documents.

It should be noted that the foregoing second network element network management system can be used as the final network element network management system or the intermediate network element network management system, and the establishment of the intermediate network element network management is not necessary, and can be continuously added in the later stage, so the intermediate network element network management The number can be one or more, thereby achieving scalability of the entire system. However, the implementation process of all the added intermediate network element network tubes can apply the present invention. Method implementation of northbound file generation of an embodiment. For the implementation process of the second network element network management system of the embodiment of the present invention, the intermediate network element network management system or the final network element network management system is as follows.

As shown in FIG. 8, the overall implementation process of the second network element network management system in the embodiment of the present invention is as follows.

Step 801: The intermediate network element network management checks whether the first northbound file has a lock file, and the lock file identifier is a completion flag. If the flag of the lock file is the completion flag, step 802 to step 805 are performed, and if the lock file is not stored, an exception may occur. Then step 806 is performed.

In step 802, the flag of the lock file is modified to be a start flag.

Step 803, adding write data to the first northbound file to generate a second northbound file.

Step 804, modifying the flag of the generated lock file of the second northbound file as a completion flag. After the modification is completed, the data of the intermediate NE management system is added.

Step 805: The intermediate network element network management checks whether the first northbound file has a lock file. If the lock file exists, the proof data is locked, and step 807 is performed. If the lock file does not exist, step 806 is performed.

Step 806, the modification is prohibited;

Step 806: Create a lock file, and set the flag of the lock file as a start flag; perform a normal process according to step 803; for example, the process of creating the first network element network management, create a northbound file, and write northbound data thereto. Since the ID of the lock file is the start flag, the data output of the second north file will fail.

As shown in FIG. 9 , in the embodiment of the present invention, the second network element network management is the final network element network management, and the overall implementation process of creating the second northbound file (ie, the final northbound file) is as follows.

In step 901, the network element network management checks whether the first/second northbound file has a lock file identifier, and the lock file identifier is a completion flag. If the flag of the lock file is the completion flag, step 902 to step 905 are performed, and if the lock file is not stored, an exception may occur. Then step 906 is performed.

In step 902, the flag of the modified lock file is a start flag.

Step 903, writing data to the first/second northbound file to generate a final northbound file.

In step 904, the flag of the lock file that generates the final northbound file is modified to be a completion flag, and the lock file is deleted. After the modification is completed, the data of the final NE network management is added.

In step 905, the network element network management finally checks whether the first/second northbound file has a lock file. If the lock file exists, the proof data is locked, step 906 is performed; if the lock file does not exist, the step is executed Step 907.

Step 906, prohibiting modification;

Step 907: Create a lock file, and set the flag of the lock file as a start flag; then execute according to the process of step 903; including creating a northbound file and writing to it according to a normal process (such as the first/second network element network management process) Enter the northbound data. Since the flag of the lock file is the start flag, the final northbound data output will fail.

As shown in FIG. 10, if the second network element network management is the final network element network management, in the method for generating a northbound file according to the embodiment of the present invention, after the step 703, the method of the embodiment of the present invention further includes:

Step 704, deleting the lock file of the second northbound file.

The delete lock file here indicates that the overall northbound file generation is completed. When the integrated network management obtains the data of the northbound file, the data of the northbound file can be judged according to the lock file. If the lock file exists, the task execution has a problem. In the implementation, it is necessary to leave sufficient execution time for each network element network management and integrated network management. In this way, when the lock file is not deleted last time, the integrated network management needs to obtain the data of the northbound file, and an unnecessary error occurs.

Determine whether it is the final NE network management, which is related to user settings. In the embodiment of the present invention, the final network element network management has the last setting data for generating a complete northbound file.

If the data of the first network element is not collected, the fault is not generated, or the first northbound file is not generated, if the first northbound file is forcibly generated from the first network element, the normal operation cannot be performed. Therefore, the embodiment of the present invention The method for generating the northbound file is the method of the embodiment of the present invention. The method further includes: when the flag of the lock file of the first northbound file is not detected as the completion flag, the flag of the lock file of the first northbound file is not the start flag. Detection. This can be adjusted according to user needs or equipment, which improves the applicability of the method.

Optionally, the method for generating a northbound file according to the embodiment of the present invention may include:

Step 7021: Acquire a write location of the first northbound file.

Step 7022: The collected data is additionally written into the first northbound file according to the obtained write position. When the additional write is completed in the embodiment of the present invention, the second northbound file is generated.

In the embodiment of the present invention, by acquiring the writing position of the first northbound file, the entire northbound file does not need to be acquired, and the write position of the first northbound file is directly added, thereby reducing the load of the second network element network management. It is also possible to generate a complete northbound file.

The method for generating the northbound file in the embodiment of the present invention further includes: a method for generating a northbound file according to the embodiment of the present invention, since the integrated network management system can obtain only one copy of the northbound file, and the new device or the new management mode may cause the interface of the integrated network management system to be incompatible.

Step 705: Send a second northbound file to the preset device, and store the second northbound file by the preset device.

It should be noted that the preset device herein may include a computer, a virtual machine, or another server, and any terminal that can store the second northbound file belongs to the protection scope of the embodiment of the present invention, and is not exemplified herein.

Also, here is the second northbound file, the northbound file output, which is a typical data output format. Usually the file output can be CSV (Comma-Separated Values, comma-separated values, the file stores the table data (number and text) in plain text), TXT (TXT is a text format that Microsoft attaches to the operating system, is the most common A file format, as early as the DOS era, a lot of applications, mainly text information, that is, text information, the current operating system is mostly saved using a program such as Notepad, most software can be viewed, such as Notepad, browser, etc. ), XML (Extensible Markup Language) or other formats. The northbound file can be located in the specified directory of FTP (File Transfer Protocol) or hard disk stored by the preset device. Northbound files have a fixed file or folder name.
