Specifically, the data loading mode of the transport network device may be a text loading manner or a database loading manner, that is, a data loading manner in the related art. If the data loading mode of the transport network device is a text loading mode, the user inputs a text generating instruction to the transport network device before performing a software/hardware upgrade for one or more services (hereinafter referred to as a transport network device upgrade). The adaptation layer forwards the instruction to the data conversion module, and the data conversion module receives the generated text instruction, and then executes the generated text instruction, and first converts the first data of the database format (DB) in the database into a text format (TXT). The second data and the second data is saved in the storage module.

In a practical application, a storage module in the transport network device, such as a non-volatile memory NVRAM, may store an identifier of the data loading mode to indicate the data loading mode used in the upgrade. For example, the data loading mode has a flag of "1", indicating that the text loading mode is used; the data loading mode has a flag of "0", indicating that the database loading mode is used. Of course, there are other representation modes, which are subject to actual application. The invention is not specifically limited.

Optionally, the identifier of the data loading mode may be set by default before the factory of the transport network device, or may be set by the user. For example, the user inputs a setting command before the upgrade of the transport network device, and the adaptation layer The instruction is forwarded to the data conversion module, and the data conversion module receives and executes the setting instruction, and sets the data loading mode to the text loading mode.

Next, the transport network device starts to upgrade. At this time, the data conversion module also needs to be added to the upgraded software package and upgraded with the software package.

S202: After the upgrade of the transport network device is successful, determine that the data loading mode is a text loading mode.

Specifically, after the second data is saved, the transport network device can start to upgrade, and after the upgrade successfully restarts the transport network device, the identifier of the data loading mode in the storage module is read, and the data loading mode is determined as the text loading mode. . The upgrade of the transport network device succeeds in that the software and/or hardware corresponding to the service is successfully upgraded, and the corresponding database upgrade is successful.

S203: Convert the second data into the third data in the database format, and load the third data into the upgraded database.

Specifically, after determining that the data loading mode is the text loading mode, the data conversion module converts the second data in the TXT format back to the third data of the DB, and then, according to the data structure and storage mode of the upgraded database, the third data is Load the upgraded database.

Optionally, after the third data is completed, the data conversion module may set the data loading mode to a database loading mode. In this way, when the transport network device is upgraded again, the user needs to manually set the data loading mode to the text loading mode, and then sequentially execute S201 to S203; or according to the database loading mode in the related art, after the upgrade of the transport network device Just load the data.

Optionally, when the transport network device is upgraded, the database is upgraded according to the new requirement, for example, changing the data structure, adding data entries, etc., at this time, after the step of converting the first data into the second data in S201, the method The method further includes: outputting the second data for the user to modify; that is, the user can copy the second data, manually modifying the second data for the upgrade, and overwriting the old data in the storage module with the modified second data. . Then, correspondingly, S203 may include: converting the modified second data into the third data.

Optionally, in order to ensure the correctness of the data, the user may also view the conversion result. Then, after the first data is converted into the second data, the user may further input a display text instruction, and the adaptation layer forwards the instruction to the data conversion. The module, the data conversion module receives the display text instruction, executes the instruction, and controls the display module to display the conversion result.

Optionally, after the modified second data covers the old data, the user may further input the display text instruction to view the modified second data.

Optionally, since there may be tens of thousands of data to be converted, in order to facilitate the user to view, after displaying the conversion result or the modified second data, the user may also input a filtering instruction, such as include/exlude/begin string, etc. To filter the second data or the modified second data for a certain service or a certain software and/or hardware.
