Method for protecting network devices

Abstract

The invention relates to the field of network communication technology, in particular to a network device. A method for protecting the network devices comprises a network device which is provided with an Ethernet control module. The Ethernet control module comprises a storage module used for storing state information of the Ethernet control module; the network device is connected with a monitoring module; in a network device running process, the state information of the Ethernet control module in the storage module is read by the monitoring module; and change conditions of the state information of the Ethernet control module are judged according to a set rule. With the adoption of the method for protecting the network devices, the running network device is protected and correspondingly processed, the data stability of the device is guaranteed, a function that the network device is interactive with external data cannot be easily lost because of abnormal conditions, so that the normal running of the device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network device. Background technique [0002] With the development of technology, some methods are used to ensure the stability of data to a certain extent in the process of data transmission on the line, but users will inevitably use corresponding network equipment when receiving data at the terminal. The existing network After the equipment is in normal operation, it is easily affected by the external environment. If there are some unexpected situations, such as: lightning strikes in rainy days, or the influence of static electricity, or incorrect operation causes current to flow into the network through the exposed metal parts of the network equipment. At this time, the Ethernet control module in the network device may be reset, resulting in the device being unable to perform data interaction with the outside world. Once the Ethernet control module fails to wor...

[0002] With the development of technology, some methods are used to ensure the stability of data to a certain extent in the process of data transmission on the line, but users will inevitably use corresponding network equipment when receiving data at the terminal. The existing network After the equipment is in normal operation, it is easily affected by the external environment. If there are some unexpected situations, such as: lightning strikes in rainy days, or the influence of static electricity, or incorrect operation causes current to flow into the network through the exposed metal parts of the network equipment. At this time, the Ethernet control module in the network device may be reset, resulting in the device being unable to perform data interaction with the outside world. Once the Ethernet control module fails to work normally, the data transmission and reception of the network device will be affected, resulting in equipment failure

[0003] like figure 1 As shown in the figure, the startup process of the original unimproved network device, after the network device is powered on, will first run the Bootloader. The function of the Bootloader is to prepare for loading the kernel and guide the kernel to start loading. Various drivers are used to initialize the device, and then the system runs normally after the initialization is completed, but in this case there is no mechanism to protect the stability of system data
