Embodiment Construction

[0024] In order to effectively improve the accuracy and efficiency of updating the main program of the line card, the embodiment of the present invention provides a method for upgrading the main program of the line card. The method includes: the line card receives the TFTP grouping of program version header information; when the main program version header information passes the verification, download the TFTP grouping containing the version body of the main program; adopt the downloaded version header of the main program and the version of the main program The main body updates its own main program. Because in the embodiment of the present invention, when the line card is updating the main program, it only downloads the TFTP packet containing the version header information of the main program at first, and only downloads the version body of the main program when it is verified that the version header information of the main program is valid. Therefore, this implementation met...

Abstract

A method and a device for upgrading a main routine of line card, which are used to solve the problems of low efficiency and poor accuracy of the update of main routine of line card in the prior art. The method comprises: when the version header information of the main routine is verified, Trivial File Transfer Protocol (TFTP) packets containing the version main body of the main routine are downloaded, and the downloaded main routine is adopted to update its own main routine. When the update of the main routine is performed in the line card, since only the TFTP packet containing the version header information of the main routine is download firstly, and the version main body of the main routine is downloaded only when the version header information of the main routine is verified to be valid, in this technical solution, the manner improves the accuracy and the security of the update of the main routine of line card, and improves the efficiency of the update of the main routine of the line card.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for upgrading a main program of a line card. Background technique [0002] With the continuous growth of various communication services, in order to meet the needs of users for different communication services, the Optical Network Unit (ONU) needs to communicate with the Optical Line Terminal (Optical Line) through the Passive Optical Network (PON) port. Terminal, OLT) connection, and also need to flexibly provide a variety of user interfaces, so as to realize the cooperation with different services. The ONU needs each line card to provide corresponding different service functions, and each line card completes a relatively single service function. [0003] figure 1 It is a schematic diagram of the position structure of the line card in the ONU in the prior art. Each line card is controlled by the main control board, and the main control board sends ea...
