Abstract
The present invention put forwards a remote file transmission method with high efficiency and reliability, which is provided by telecommunication level equipment. The method realizes the function of file transmission based on a TFTP protocol (Trivial Transfer Protocol, trivial file transfer protocol). The present invention has the basic clew that when files are transmitted from a network terminal storing transmission files to a master control board, a TFTP server is started up on the network terminal, and a TFTP client terminal is started up on the master control board so as to realize the file transmission between the network terminal and the master control board. When the second stage transmission of the files is carried out, the TFTP server is operated on the master control board, TFTP client terminal programs are started up on a service single board, and the files are transmitted to the service single board by using the TFTP protocol again. The method of the present invention fully uses the trivial file transfer protocol so as to realize the file transmission without saving the files to a quick flash memory, and the present invention has the advantages of high read-write efficiency and relatively simple realization.
