Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for repairing an image file, an AP device, and a network system.

Background

An image file of an AP (Access Point) device is generally stored in a non-volatile flash memory (NOR flash), and the capacity of the NOR flash memory is generally 1 to 32 megabits, and the larger the capacity is, the higher the price is. The mirror file belongs to a running system file and is from several to tens of megabits in size. During the operation of the system, the image file can be modified or damaged accidentally. Once the image file of the AP device is damaged, the system of the AP device cannot be normally started, and a worker often needs to go to a field to replace the device and then take back to repair the device, which results in high maintenance cost.

Further, the components shown in fig. 2 may be implemented by software, hardware, or a combination thereof.

Referring to fig. 3, fig. 3 is a flowchart illustrating steps of a method for repairing an image file according to an embodiment of the present application, where the method is applied to an AP device in a network system, where the AP device may be any device in the network system. It should be noted that, the method for repairing an image file provided in the embodiment of the present application is not limited by the sequence shown in fig. 3 and the following, and the method includes: step S101 to step S104.

Step S101: after determining a damaged paging file in a self-stored image file, constructing an image repairing request message; the mirror image repair request message includes the device model, the device version number, and the number of the damaged paging file.

The AP device may store the image file in a NOR flash nonvolatile flash memory. Non-volatile flash memory typically stores two types of files, uboot files and image files. The uboot file is a system starting boot file, and the image file is a mirror image file. uboot files are generally not corrupted, while image files may be modified or accidentally corrupted. Once the image file of the device is damaged, the system cannot be started normally.

The information included in the image file may be referred to the following table:

the Image file includes an Image header (Image head) and an Image body (Image body).

The mirror image head includes: device Model (Model), mirror Version number (Version), mirror Body Page number (Page number), mirror Body check value (Body CRC or MD5), mirror Body Page check value (Page1 CRC or MD 5).

The device model is used for determining whether the mirror image main body is matched with the hardware device, and if not, the mirror image main body cannot be normally started.

The image version number is the version number corresponding to the image body.

The mirror image body refers to a file required by the running of the AP equipment, the file can be divided into a plurality of pages according to the size, each page is numbered in sequence, and the size of each page is fixed.

The mirror body Check value is obtained by performing CRC (Cyclic Redundancy Check) or MD5(Message Digest Algorithm 5) Check on the mirror body.

The mirror body page check value is obtained by performing a CRC or MD5 check on each page file. Illustratively, if the image file is divided into 48 pages, the image file includes 48 page files, and the image header includes 48 image body page check values.

Since CRC checks and MD5 checks are well known in the art, this application is not overly elaborated. It should be noted that, in general, the mirror body check value and the mirror body page check value are checked in the same way, such as both CRC checks or both MD5 checks.

The specific detection process of the AP equipment on the mirror image file is as follows: the AP equipment starts the mirror image file by using a uboot bootstrap program, and before starting, the mirror image main body check value is checked. The mirror body is checked for CRC or MD5 to obtain a check value (the check method used here is the same as the check method corresponding to the stored check value), and then compared with the mirror body check value in the mirror header. If the version is consistent with the version, the verification is successful, and the version is started normally; and if the two numbers are not consistent, the check fails, and the boot mode of the uboot bootstrap program is entered. The network communication function, such as message receiving and sending, is still provided in the Boot mode.

When the image file is determined to be damaged, the damaged paging file in the image file needs to be determined. The specific process is as follows: and sequentially performing CRC or MD5 check on each paging file to obtain a corresponding check value (the check mode adopted here is consistent with the check mode corresponding to the stored check value), and then comparing the obtained check value of each paging file with the corresponding paging check value of the mirror body in the mirror header. If the paging file is consistent with the paging file, the current paging file is not damaged, if the paging file is inconsistent with the paging file, the current paging file is damaged, and then the number of the damaged paging file is recorded.

It should be noted that determining the damaged paging file in the image file may be performed in Boot mode. In the mode, the mirror image main body check value can be checked again so as to perform secondary check on the mirror image file and reduce misjudgment on the verification result of the mirror image file.

And after determining the number of the damaged paging file, constructing a mirror image repair request message. The mirror image repair request message includes the device model, the device version number, and the number of the damaged paging file. The AP devices with the same device model and device version number have the same image file, and the image main bodies in the image file are also the same. Therefore, the mirror image repair request message carries the device model and the device version number so as to find out the AP device having the same device model and the same device version number in the network system.

Step S102: and broadcasting the mirror image repair request message so that other AP equipment in the network system receives the mirror image repair request message.

After the mirror image repair request message is constructed, the AP equipment sends the message in a network system in a broadcasting mode, so that other AP equipment in the network system can receive the mirror image repair request message.

Step S103: receiving a repair data response message sent by other AP equipment; the other AP equipment and the AP equipment have the same equipment model and the same equipment version number; the repair data response message includes paging file data corresponding to the number of the damaged paging file.

After receiving the mirror image repair request message, other AP equipment in the network system analyzes the message, judges whether the equipment model and the equipment version number carried by the message are consistent with the equipment model and the equipment version number of the AP equipment, judges whether the AP equipment comprises paging file data corresponding to the number of the damaged paging file if the equipment model and the equipment version number are consistent, and sends a repair data response message to the AP equipment which sends out the broadcast if the AP equipment comprises the paging file data corresponding to the number of the damaged paging file. The repair data response message includes paging file data corresponding to the number of the damaged paging file.

It should be noted that, after analyzing the device model and the device version number carried in the packet, other AP devices in the network system further determine whether each AP device includes paging file data corresponding to the number of the damaged paging file only when determining that the device model of each AP device is identical to the device model carried in the packet and the device version number of each AP device is also identical to the device version number carried in the packet. And if any one of the information is inconsistent, directly discarding the mirror image repair request message. Since AP devices having the same device model and device version number have the same image file in general, the AP devices having the same device model and device version number may have paging file data corresponding to the number of the damaged paging file. However, an abnormal condition may also occur in the device, and therefore, if the AP device with the same device model and device version number does not include paging file data corresponding to the number of the damaged paging file, the device also discards the mirror image repair request message.

Step S104: and repairing the mirror image file based on the paging file data.

And finally, the AP equipment analyzes the received repair data response message, and repairs the mirror image file based on the paging file data after analyzing the received repair data response message to obtain the paging file data.

After the AP device obtains the paging file data through parsing, the AP device may check the paging file data first, for example, perform CRC or MD5 check on the paging file data to obtain a corresponding check value, and then compare the obtained check value with a corresponding mirror image main body paging check value in the mirror image header. And if the check values are consistent, replacing the damaged paging file with the paging file data, at the moment, successfully repairing the mirror image file of the AP equipment, and automatically restarting the AP equipment after successful repair. And if the check values are inconsistent, the repair of the mirror image file of the AP equipment fails.

In summary, in the embodiment of the present application, after the AP device determines a damaged paging file in the image file stored in the AP device, the AP device sends an image repair request message to other AP devices in the same network system, and then completes the repair of the image file by using paging file data transmitted by the AP devices having the same device model and the same device version number in the same network system.

Referring to fig. 4, based on the same inventive concept, an embodiment of the present application further provides a method for repairing an image file, where the method is also applied to any AP device in a network system. It should be noted that, the method for repairing an image file provided in the embodiment of the present application is not limited by the sequence shown in fig. 4 and the following, and the method includes: step S201 to step S206.

Step S201: after determining a damaged paging file in a self-stored image file, constructing an image repairing request message; the mirror image repair request message includes the device model, the device version number, and the number of the damaged paging file.

Step S202: and broadcasting the mirror image repair request message so that other AP equipment in the network system receives the mirror image repair request message.

It should be noted that, since the steps S201 to S202 are the same as the steps S101 to S102, the description is omitted here for the sake of avoiding redundancy, and the same parts may be referred to each other.

Step S203: receiving mirror image repair confirmation messages sent by other AP equipment; wherein, the mirror image repair confirmation message includes the number of the damaged paging file.

The other AP devices and the AP device have the same device model and the same device version number. After receiving the mirror image repair request message, other AP equipment in the network system analyzes the message, judges whether the message is consistent with the equipment model and the equipment version number of the AP equipment after analyzing the equipment model and the equipment version number carried by the message, judges whether the AP equipment comprises paging file data corresponding to the number of the damaged paging file if the message is consistent with the equipment model and the equipment version number of the AP equipment, and sends a mirror image repair confirmation message to the AP equipment which sends out the broadcast if the message is consistent with the paging file data. The image repair confirmation message represents that other AP equipment can send paging file data corresponding to the damaged paging file to the AP equipment which sends the broadcast.

After analyzing the device model and the device version number carried by the message, other AP devices in the network system further determine whether or not they include paging file data corresponding to the number of the damaged paging file only when it is determined that the device model of each AP device is identical to the device model carried by the message and the device version number of each AP device is identical to the device version number carried by the message. And if any one of the information is inconsistent, directly discarding the mirror image repair request message. Since AP devices having the same device model and device version number have the same image file in general, the AP devices having the same device model and device version number may have paging file data corresponding to the number of the damaged paging file. However, an abnormal condition may also occur in the device, and therefore, if the AP device with the same device model and device version number does not include paging file data corresponding to the number of the damaged paging file, the device also discards the mirror image repair request message.

Step S204: and sending a repair data request message to other AP equipment, wherein the repair data request message comprises the number of the damaged paging file.

After receiving the mirror image repair confirmation message sent by other AP equipment, the AP equipment analyzes the message, and after obtaining the number carried in the message and determining that the number is the number of the damaged paging file required by the AP equipment, sends a repair data request message to other AP equipment so that the other AP equipment sends paging file data corresponding to the number of the damaged paging file to the AP equipment.

In an embodiment, the network system has a plurality of other AP devices having the same device model and the same device version number as the AP device, and each of the plurality of other AP devices includes paging file data corresponding to a number of a damaged paging file of the AP device. Before sending a repair data request message to other AP devices in step S204, the method further includes: receiving mirror image repair confirmation messages sent by a plurality of other AP devices; the mirror image repairing confirmation message comprises the number of the damaged paging file; determining one AP device in a plurality of other AP devices as a target AP device; the target AP equipment is the AP equipment which sends a repair data request message, wherein the repair data request message comprises the number of the damaged paging file.

That is, after receiving the mirror repair confirmation messages sent by the multiple other AP devices, the AP device determines one of the other AP devices as the destination AP device, and then sends the repair data request message only to the destination AP device. By the method, the condition that other AP equipment also sends the repair data response message to the AP equipment can be avoided, and further, excessive communication link resources are avoided being occupied.

As a way of optionally determining the destination AP device, determining, in the above step, one AP device in the multiple other AP devices as the destination AP device may include: acquiring the MAC address of each other AP device from mirror image repair confirmation messages sent by the other AP devices; and determining the AP device with the minimum MAC address as the destination AP device.

In this way, the AP device with the minimum MAC address is used as the destination AP device, and the destination AP device can be determined reasonably.

As another alternative way of determining the destination AP device, determining, in the above step, one AP device in the multiple other AP devices as the destination AP device may include: acquiring the receiving time of receiving the mirror image repair confirmation message sent by each other AP device; the AP device with the earliest reception time is determined as the destination AP device.

In this way, the AP device corresponding to the received first mirror repair acknowledgement packet may be determined as the destination AP device, and by this way, the destination AP device may be determined as fast as possible.

Of course, in other embodiments, the AP device with the largest MAC address may also be determined as the destination AP device, and specifically, what manner of determining the destination AP device is adopted may be determined according to actual requirements, which is not limited in this application.

Step S205: receiving a repair data response message sent by other AP equipment; the repair data response message includes paging file data corresponding to the number of the damaged paging file.

After receiving the repair data request message sent by the AP device, the other AP devices construct a repair data response message, and then send the paging file data corresponding to the number of the damaged paging file to the AP device. And when the network system has a plurality of other AP devices with the same device model and the same device version number as the AP device, receiving the repair data response message sent by the determined target AP device.

Step S206: and repairing the mirror image file based on the paging file data.

And finally, the AP equipment analyzes the received repair data response message, and repairs the mirror image file based on the paging file data after analyzing the received repair data response message to obtain the paging file data.

After the AP device obtains the paging file data through parsing, the AP device may check the paging file data first, for example, perform CRC or MD5 check on the paging file data to obtain a corresponding check value, and then compare the obtained check value with a corresponding mirror image main body paging check value in the mirror image header. And if the check values are consistent, replacing the damaged paging file with the paging file data, and at the moment, successfully repairing the mirror image file of the AP equipment. And if the check values are inconsistent, the repair of the mirror image file of the AP equipment fails.

In addition, when the image file is failed to be repaired based on the paging file data, and at this time, the network system has a plurality of other AP devices having the same device model and the same device version number as the AP device, and the other AP devices all include the paging file data corresponding to the number of the damaged paging file of the AP device, the method further includes: determining one of the remaining plurality of other AP devices as a new destination AP device; sending the repair data request message to new target AP equipment, wherein the repair data request message comprises the number of the damaged paging file; receiving a repair data response message sent by new target AP equipment; the repair data response message sent by the new target AP equipment comprises paging file data corresponding to the number of the damaged paging file; and repairing the mirror image file based on paging file data in a repair data response message sent by the new target AP equipment.

That is, after the AP device fails to repair the image file by using the paging file data sent by one of the other AP devices, the AP device determines, from the remaining other AP devices, the next AP device to which the repair data request message needs to be sent, and then repairs the image file based on the paging file data returned by the next AP device, and so on until the AP device succeeds in repairing the image file, or fails to repair the image file based on all the paging file data sent by the other AP devices.

In addition, when the AP device determines that the number of the damaged paging file is multiple, it may sequentially send a repair data request message corresponding to one of the numbers to other AP devices, or may simultaneously include the numbers of all the damaged paging files in the repair data request message sent to other AP devices.

Illustratively, the AP device determines the numbers of the damaged paging file to be four, five, and six. When other AP devices have paging file data corresponding to numbers four, five, and six, the AP device may first send a repair data request message corresponding to number four, that is, the message only includes number four, but does not include numbers five and six. The message is only used to request paging file data corresponding to the damaged paging file number four from other AP devices. The AP equipment obtains paging file data corresponding to the damaged paging file with the number of four, and then sends a repair data request message corresponding to the number of five to other AP equipment. The AP equipment obtains paging file data corresponding to the number five of the damaged paging file, and then sends a repair data request message corresponding to the number six to other AP equipment.

Illustratively, the AP device determines the numbers of the damaged paging file to be four, five, and six. When other AP devices have paging file data with numbers of four, five, and six, the repair data request packet sent by the AP device may include numbers of four, five, and six at the same time, so that the other AP devices transmit paging file data with numbers of four, five, and six to the AP device at the same time.

In summary, in the embodiment of the present application, before receiving the repair data response message sent by the other AP device, the AP device needs to perform a handshake with the other AP device first, that is, receive the mirror repair confirmation message sent by the other AP device first, so as to determine that the other AP device can send the paging file data corresponding to the number of the damaged paging file. By the method, the accuracy and the reliability of obtaining the paging file data corresponding to the number of the damaged paging file can be improved, and the condition that the AP equipment analyzes the received repair data response message for multiple times to determine whether the message contains the paging file data corresponding to the number of the damaged paging file is avoided.

Referring to fig. 5, based on the same inventive concept, an embodiment of the present application further provides an image file repairing apparatus 200, applied to an AP device in a network system, where the apparatus includes:

the constructing module 210 is configured to construct a mirror image repair request message after determining a damaged paging file in a mirror image file stored in the constructing module; the mirror image repair request message comprises a device model, a device version number and the number of the damaged paging file.
