Abstract

PURPOSE: A method for loading an internal system file is provided to load the internal system file in case that a system is installed in a remote place by storing the internal system file in a computer connected with the system and transmitting the internal system file to the system. CONSTITUTION: An FTP(File Transfer Protocol) server performs a log-in process(S42), loads an internal system file, and opens a new data channel(S43). If an operator inputs a transfer command for transmitting a new internal system file and a name of the internal system file on an FTP command prompt, a corresponding computer transmits a new internal system file to the FTP server through the Internet(S44). The child process generated by the FTP server continuously stores the new internal system file in a buffer(S45) and checks whether the corresponding buffer is full(S46). If the buffer is full, the child process temporarily stops the transmission of the new internal system file, and searches a file table of a current system for searching information regarding a write position on a flash memory to record the new internal system file(S47) and writes the new internal system file in the corresponding write position on the flash memory(S48). The FTP server stores the new internal system file in the flash memory and judges whether the transmission of the new internal system file is ended from the computer(S49). If the transmission of the new internal system file is ended, the FTP server stops the child process. The operator confirms version information of the system, downloads the new internal system file stored in the flash memory to an operator's own computer through the Internet, compares the downloaded new internal system file with an original internal system file stored in the computer, and checks whether the downloaded new internal system file is abnormal(S50,S51). If the loading internal system file is correctly transmitted, the operator transmits a command for booting the system to the FTP server and the FTP server performs the booting of the system for applying the new internal system file to the system(S52).

Description

Loading method of file in system using internet}

The present invention relates to a method for loading an internal file system using the Internet, and more particularly, to a method for loading an internal file system using the Internet for maintaining a system file and a configuration file, which are mounted and operated in the system, without a direct visit by an operator. .

In general, when there is a need to change or update a function performed by a system or a service provided, a system internal file such as a system file or a configuration file that is mounted in the system and performs functions required for operating the system is replaced or In order to update, a new system internal file must be loaded into the system.

In order to load the system internal file, a system internal file is downloaded by downloading a new system internal file to the system using a TFTP server (Trivial File Transfer Protocol Server), which is conventionally connected to the system via a local area network (LAN). Loaded into the system.

1 is a diagram illustrating a network conceptual diagram for loading a conventional system internal file.

Conventionally, a TFTP server 14 connected through a system 16 and a LAN 10 and a serial interface of the system 16 are connected to load a new system internal file into the system 16. Console 12 was used.

At this time, the console 12 has an input / output device such as a monitor and a keyboard for performing maintenance work on the system 16, and the TFTP server 14 has a TFTP protocol when there is a request from the system 16. The system downloads a new system internal file to be loaded into the system 16, which is stored in itself. The TFTP protocol is a file transfer protocol using UDP (User Datagram Protocol) that does not have an error correction or retransmission function. It is often used in cases where a high transfer rate is required rather than reliability, such as a small file transfer in an environment.

The system 16 downloads a system internal file from the TFTP server 14 and stores the internal file in a flash memory inside the system 16, and communicates with the LAN interface for communication with the TFTP server 14 or the console 12. It is equipped with a console interface and must support the TFTP protocol in order to download system internal files from the TFTP server 14.

A process of loading a conventional system internal file will be described in detail with reference to the flowchart shown in FIG. 2.

If there is a need to replace or update the system internal files stored in the system 16, in order to download the new system internal files to the system, the system operator runs the TFTP server 14 and simultaneously downloads the new system internal files to download. The file is stored in the TFTP server 14 (S20).

After logging in to the system 16 through the console 12 (S21), a file transfer command for downloading a new system internal file stored in the TFTP server 14 to the system, and the TFTP server 14 ) Is transmitted to the system 16 (S22).

Thereafter, after rebooting the system 16 to designate an IP address for the TFTP server 14 in which a new system internal file to be downloaded to the system 16 is stored (S23), the TFTP is used using the IP address. The server 14 is connected to the server 14 (S24), and the file transfer command is transmitted to the TFTP server 14 (S25).

Accordingly, the TFTP server 14 receiving the file transfer command from the system 16 starts to download the system internal file to be loaded to the system 16 via the LAN 10, and the system 16 starts the TFTP server ( At the same time as downloading the system internal file transmitted from the 14), the downloaded system internal files are sequentially recorded and stored in the internal flash memory (S26).

Thereafter, the system 16 determines whether the download of the system internal file transmitted by the TFTP server 14 is completed (S27), and if the download of the system internal file is not completed, the process of S26 is performed. Repeating and, if the download of the system internal file is completed, the system 16 is rebooted again so that the downloaded system internal file operates normally (S28).

However, the above-described conventional method of loading an internal system file has the following problems.

First, since the system internal file should be loaded by using the TFTP server and console connected to the system through LAN, when the system is installed in the remote place, the operator should directly visit the remote site and load the internal file in the system. There was discomfort.

Next, in order to download a new system internal file from the system side, you need to specify the IP address of the TFTP server where the system internal file is stored and access the TFTP server. The location of the TFTP server where the new system internal file is stored may change. Whenever you load a file inside the system, you must check the IP address of the TFTP server that stores the file and send it to the system.

In addition, in order to specify the IP address of the TFTP server, there is an inconvenience in that the operator must reboot the system before starting to load the system internal file.

Finally, conventionally, since a system internal file is transmitted using a TFTP protocol using UDP, there is a problem that an error that occurs when an error occurs during system internal file transfer cannot be recovered.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an object thereof is to store a system internal file to be loaded in a computer connected to the system via the Internet, and transmit the system internal file to the system via the Internet to a system internal file. By performing the loading operation for the system, even if the system is installed at a remote location, the operator can easily load the internal file from the current location without having to go to the remote location, and data loss that may occur while transferring the internal file is performed. In addition to minimizing errors, it is possible to perform internal file loading without rebooting the system.

A feature of the present invention for achieving the above object is that, when you want to load the internal file of the system, by using a computer connected to the Internet to access the FTP server of the system side to transfer a new system internal file Process; Receiving the system internal file transmitted through the internet and storing the internal file in a system flash memory; Rebooting the system to apply the new system internal files stored in the flash memory to the system to provide a system internal file loading method using the Internet.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, when it is necessary to replace or update an existing system internal file that is mounted and operated in a system, by using a computer connected to the system via the Internet, a new system internal file to be loaded is transmitted to the system. This is to replace or update the internal system file.

3 is a conceptual diagram of a network for loading a system internal file illustrated in FIG. 3 of the accompanying drawings. The system 300 is basically a system 300 connected to the computer 32 and the computer 32 through the Internet 30.

At this time, the computer 32 stores the FTP client program and the new system internal file to be loaded, and then transmits the new system internal file to the system 300 when the system internal file needs to be loaded.

The system 300 includes a network interface 310, an FTP server 320, a buffer 330, a file table 340, and a flash memory 350. have.

In more detail, the network interface 310 provides an interface for accessing the 30, and the FTP server 320 connected to the Internet 30 through the network interface 310 is a child processor. Receives the system internal file transmitted from the computer 32, and stores it in the buffer 330, which is a temporary storage, while storing the internal file on the flash memory 350 in the location where the internal file is to be written The file is deleted and a new system internal file stored in the buffer 330 is stored in the corresponding location. In the embodiment of FIG. 3, the storage capacity of the buffer 330 is set to 512 bytes corresponding to one sector storage capacity of the flash memory 350.

On the other hand, the file table 340 relates to a write position indicating at which position on the flash memory 350 the system internal file stored in the buffer 330, the size of the new system internal file, and the like. It is storing information. The child process of the FTP server searches the file table 340 to determine the recording location on the flash memory 350.

4 is a flowchart illustrating a process of loading a system internal file using the Internet according to the present invention.

First, when the operator wants to replace or update the internal file of the system 300 managed by the operator, after checking the IP address of the corresponding system 300, the FTP client program embedded in the computer 32 and The IP address is used to access the system 300 through the Internet 30 (S41).

At this time, the FTP server 320 which is being performed in the system 300 has an ID for authentication to the computer 32 side as the operator's computer 32 accesses the system 300 through the Internet 30. If the user is authenticated by inputting a password and authenticated as a legitimate user, after the login process is performed (S42), a child process for loading the system internal file is created and a new data channel is opened (S43). In this case, if several operators try to load the internal file at the same time, it is preferable to create only one child process because the loaded internal file may malfunction or be suddenly down during operation. .

On the other hand, after the new data channel is opened, the FTP server enters a transfer command for transferring a new system internal file on the FTP command prompt of the computer 32 and the name of the new system internal file to be transferred. 32 starts transmitting new system internal files stored therein to the FTP server 320 through the Internet 30 (S44).

Accordingly, the child process generated by the FTP server 320 continuously stores a new system internal file transmitted from the computer 32 through the Internet 30 in the buffer 330 (S45), and the corresponding buffer 330 Check whether it is full (S46), and if the buffer 330 is not full yet, repeating the process of S45 and continuously receiving a new system internal file and storing it in the buffer 330.

However, when the buffer 330 becomes full, the transmission of a new system internal file may be interrupted for a while, and then the new system internal file may be recorded by searching the file table 340 in the current system 300. Information about the write position on the flash memory 350 is found (S47), and the information is written to the corresponding write position on the flash memory 350 (S48).

Then, the FTP server 320 determines whether the transmission of the new system internal file from the computer 32 is terminated while storing the new system internal file in the flash memory 350 according to the above-described operation (S49). If the file transfer is not completed, the process of S45 is repeated to continuously receive the new system internal file and store the file in the flash memory 350. However, when the transfer of the new internal system file is terminated, the child process that has been loading the corresponding internal system file is terminated. At this time, the operator checks the version information of the system 300 and uses the 'get' command provided by the FTP client program to access the Internet 30 from a new system internal file stored in the flash memory 350 of the system 300. It is downloaded back to its own computer 32 and compared with the original system internal file stored in its own computer 32 to check for abnormalities (S50, S51).

As a result of the abnormality check, if the system internal file to be loaded is correctly transmitted, the command to reboot the system 300 is transmitted to the FTP server by using the 'reset' command provided by the FTP client program. By rebooting 300, a new system internal file is applied to the system 300 (S52).

If the system internal file stored in the computer 32 does not match the transmitted system internal file in the process of S51, the process returns to the process of S44 to restart the transmission of the new system internal file from the beginning.

In the above-described embodiment, the system 300 is rebooted when there is no error after checking whether the transmission of the system internal file is correct. However, after rebooting the system 300, it is determined whether the internal file transmission is correct. Embodiments are also possible.

The process of loading the system internal file using the above-described Internet will be described with a specific example.

For example, because a new MGCP protocol has been added to the system, if an operator in Seoul needs to replace all internal operating software of a system installed in Busan, the operator first checks the IP address of the system installed in Busan, and then Log in to the system in Busan using your connected office PC. After logging in, type 'Put flash.bin system boot' at the FTP prompt and the newly created file 'flash.bin' will be started. After all the files have been transferred, the system will automatically reset and terminate the client FTP program. After a while, log in again using Telnet and check the system version information. If you want to check whether the newly replaced program has been transferred correctly, use the 'get' command at the FTP prompt to download the internal system file stored in the flash memory to your computer, and then save the original file stored in your PC. Compare to a file.

Although the present invention has been described in detail only with respect to the above-described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the present invention, and such modifications or changes are within the scope of the claims of the present invention. Will belong.

As described above, the present invention loads the internal file of the system into the system by FTP method using a computer connected to the system and the Internet, so that the operator can easily load the internal file of the system without directly visiting the place where the system is located. After loading the system files, the downloaded system files can be downloaded to the operator's computer to check whether the system files are loaded correctly into the system, and it is necessary to reboot the system before loading the system files. This makes it possible to load internal files while the system is running.
