Problems solved by technology

The process of transferring files from the main control board to other single boards is realized in the existing technology, and it is usually necessary to establish a communication link between the main control board and the single board in advance, and realize it through a specific unpacking process. At the end, the process of grouping is also required. After the grouping is completed, the file is written to the flash memory. This method cannot effectively use the mature TFTP technology, and it is more complicated to implement and less efficient.

[0011] Specific examples: figure 1 It is a schematic diagram of the system structure of the method of the present invention; when transferring files from the network terminal to the main control board, the TFTP Server is set up on the network terminal, the TFTP Client program is run on the main control board, and the main control board initiates the TFTP session. When transferring files from the main control board to the service single board, a TFTP Server is established on the main control board, and the TFTP Client program is run on the service single board, and the service single board initiates a TFTP session. The data transmission path is from the storage medium of the network terminal to the memory (virtual disk) of the main control board, and then to the fast flash memory of the service board. figure 2 It is a flow chart of the method of the present invention. In the present invention, since the TFTP server end needs to conform to the file system of the POSIX standard...

Abstract

This invention provides a telecommunication level high efficiency, reliable remote file transfer method realizing file transfer function based on TFTP (trivial file transfer protocol). The basic idea is to start TFTP server on network terminal and start TFTP customer end on the main control panel to realize file transfer between them, and at the second level file transfer, TFTP server operates on the main control panel and TFTP customer program is started at service single panel, again to utilize TFTP protocol to transfer file to the service single panel, fully utilizing TFTP to realize file transfer without storing file in flash memory first with very high read, write efficiency. 0

Description

Technical field: [0001] The invention relates to a method for remote file transmission in the communication field, in particular to a method for remote file transmission of telecom-grade equipment based on IP technology. Background technique: [0002] In carrier-class products, there are usually multiple core main control boards for system control and multiple service single boards for service processing in the equipment. Each board may have version files and configuration files, etc., and the files are usually stored on the flash memory (Flashmemory) of the board. When upgrading the system version or modifying configuration files, it will inevitably involve file transfer issues. When transferring files to a specific board, the board needs to be addressed. The system has an external IP address for remote addressing on the network. According to the index number of the board, the target object of the current file transfer can be known. When the target object of file transmiss...
