Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] refer to Figure 1 to Figure 4 The present invention provides a method for remotely upgrading a serial port of a network device, the network device is an embedded network device based on a LINUX operating system, and the method includes an upgrade operation step of an upgrade terminal and an upgrade operation step of a network device to be upgraded. Wherein, the upgrade terminal is a host computer.

[0040] Such as figure 1 and figure 2 As shown, the upgrade operation steps for upgrading the terminal include:

[0041]S1. Establish a connection between the upgrading terminal and the network device to be upgraded through a serial port cable, and obtain the serial port number corresponding to the serial port used by the network device to be upgraded from the upgrading interface of the upgrading terminal.

[0042] S2. Acquire locally the softwar...

Abstract

The invention relates to a remote serial port upgrade method of network devices. The upgrade operation steps of an upgraded terminal comprise: S1, obtaining a serial port number corresponding to a serial port used by a network device to be upgraded; S2, obtaining a software version needing to be upgraded of the network device to be upgraded from the local, and sending an upgrade start check command to the network device to be upgraded; S3, sending upgrade file data packets to the network device to be upgraded, wherein a plurality of upgrade file data packets are sent, and if a receiving success command of the upgrade file data packet returned by the network device to be upgraded is received before reaching an overtime threshold, sending the next upgrade file data packet; and S4, sending anupgrade end command to the network device to be upgraded, wherein and the upgrade end command comprises a version file length and a version file CRC, and if an upgrade success command returned by thenetwork device to be upgraded is received, indicating the completion of the upgrade operation of the upgraded terminal. By adoption of the remote serial port upgrade method provided by the invention,the remote upgrade of the programs of the network devices in batches can be achieved in a serial port manner, thereby reducing the workload and the cost.

Description

【Technical field】 [0001] The invention relates to a serial port remote upgrading method of an embedded network device based on a LINUX operating system. 【Background technique】 [0002] When the network equipment running on the network in the project needs to fix bugs (vulnerabilities) or add new functions, it usually needs to update the program, that is, program upgrade. However, in the case of a large number of network devices and scattered distances, if the upgrade is performed point-to-point and one by one, the workload will be relatively large, the operation will be inconvenient, and the labor cost will be high. [0003] Therefore, there is an urgent need for a remote upgrade method that can realize program upgrades of batches of network devices. 【Content of invention】 [0004] The purpose of the present invention is to overcome the shortcomings of the above technologies, and provide a serial port remote upgrade method of network equipment, which can realize remote up...
