Background
An image file of an AP (Access Point) device is typically stored in a non-volatile flash (NOR flash). A nonvolatile flash memory is a memory in which stored data does not disappear after a current is interrupted. The larger the capacity of the nonvolatile flash memory, the higher the price. The image file belongs to an operating system file, with the continuous development of wireless WLAN (Wireless Local Area Network ) technology, the technology is more and more complex, the functions are more and more, and the image file of the AP equipment is larger and larger.

It should be noted that the structure shown in fig. 2 is only illustrative, and the AP device 100 provided in the embodiment of the present application may further have fewer or more components than those shown in fig. 2, or may have a different configuration from that shown in fig. 2. In addition, 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 an image file configuration method according to an embodiment of the present application, where the method is applied to an AP device in a network system, and the AP device may be any device in the network system. It should be noted that, the image file configuration method provided in the embodiment of the present application is not limited to the sequence shown in fig. 3 and the following description, and the method includes: step S101 to step S104.
Step S101: and acquiring an image file of the system version to be configured.
The AP device may log in to an AP page or a command interface through any manner such as Web (world wide Web), SSh (secure shell), telnet (remote terminal protocol), serial port, etc. to receive an image file of a version of a system to be configured. The image file of the system version to be configured can be an image file of the system version to be upgraded, or can be an image file of the AP equipment when being configured for the first time. That is, step S101 may be performed when the AP device upgrades the system version, or may be performed when the AP device configures the image file for the first time.
After the AP equipment acquires the image file of the system version to be configured, the image file can be downloaded into the local memory.
In an embodiment, after acquiring the image file of the system version to be configured, the AP device further acquires a CRC value of the image file. Correspondingly, the AP device may further perform CRC (Cyclic Redundancy Check ) check on the image file, and then determine whether the image file is error-free by comparing whether the CRC check value obtained by the self check is consistent with the acquired CRC check value. And when the CRC check value obtained by self check is consistent with the obtained CRC check value, representing the image file without errors, and executing the subsequent steps at the moment. When the CRC check value obtained by self check is inconsistent with the obtained CRC check value, the image file is represented as error, and at the moment, the AP equipment can acquire the image file of the system version to be configured again.
Since the CRC check is a check manner well known in the art, this application will not be described in any great detail.
Step S102: determining the segmentation number of the mirror image file according to the number of the AP devices which are obtained in advance and have the same manufacturer and model as the AP devices in the network system; the number of segments of the image file is not greater than the number of AP devices with the same manufacturer and model as the AP devices in the network system.
When counting the number of AP devices having the same manufacturer and model as the present device, it is necessary to calculate the number. For example, the manufacturer of the device is V1, and the model is X1. The network system further comprises three AP devices with the manufacturer of V1 and the model of X1, and the number of the AP devices with the same manufacturer and model as the AP devices in the network system is four.
In step S102, the AP device determines the number of segments of the image file according to the number of AP devices having the same manufacturer and model as the AP device in the network system acquired in advance after acquiring the image file.
In an embodiment, the number of segments of the image file may be equal to the number of AP devices in the network system having the same manufacturer and model as the present device.
For example, if the number of AP devices in the network system, which have the same manufacturer and model as the present device, is four, the number of segments of the image file is four. That is, the image file is divided into four segment files.
In another embodiment, the number of segments of the image file is half the number of AP devices in the network system that have the same manufacturer and model as the present device.
For example, if the number of AP devices in the network system, which have the same manufacturer and model as the present device, is four, the number of segments of the image file is two. That is, the image file is divided into two segment files.
It should be noted that, when the number of segments of the image file is half of the number of AP devices having the same manufacturer and model as the device in the network system, the same segment file can be stored in two AP devices at the same time subsequently, so as to complete backup of one segment file.
Furthermore, it should be noted that the minimum unit of the segmented file is 64Kb (kilobytes) or 128Kb (which is determined by the minimum read-write unit of the nonvolatile flash memory device).
In the embodiment of the present application, the method may obtain an AP device having the same manufacturer and model as the present device in a network system through the following steps: constructing a device discovery message; the device discovery message comprises a manufacturer, a model and a device address; broadcasting the equipment discovery message to enable other AP equipment in the network system to receive the equipment discovery message; receiving device response messages sent by other AP devices; other AP equipment and the equipment have the same manufacturer and model; the equipment response message comprises a manufacturer, a model and an equipment address; and determining the number of the AP devices with the same manufacturer and model as the equipment and the same manufacturer and model as the equipment based on the equipment response message.
The process of acquiring the AP devices having the same manufacturer and model as the present device in the network system may be performed before step S101 is performed. The above process is a process in which the AP device searches for AP devices having the same manufacturer and model in the network system.
Specifically, after logging in, the AP device performs a device search operation. Firstly, a device discovery message is constructed, wherein the message carries the manufacturer, the model and the device address of the device discovery message. Wherein the device address may comprise an IP (Internet Protocol ) address and/or a MAC (Media Access ControlAddress ) address. The device discovery message may be, but is not limited to, a UDP (User Datagram Protocol, user data packet protocol) message. The AP device then broadcasts the message over the network. After receiving the device discovery message, other AP devices in the network analyze the device discovery message, then judge whether the manufacturer and model carried by the message are consistent with the AP devices, if not, discard the message. If the device discovery messages are consistent, the AP device constructs device response messages to reply the AP device which sends the device discovery messages. The device response message also includes manufacturer, model and device address. After receiving the device response messages sent by other AP devices in the network system, the device can determine the AP devices with the same manufacturer and model as the device and the number of the AP devices with the same manufacturer and model as the device.
In addition, the device can also establish a distributed AP device table after receiving device response messages sent by other AP devices in the network system. The established distributed AP device table may refer to table one.
List one
As shown in table one, the distributed AP device table includes devices, manufacturers, models, MAC addresses, and IP addresses. Assuming that the device is AP1, the number of AP devices in the network system having the same manufacturer and model as the device is four (i.e., AP1, AP2, AP3, and AP 4).
It can be seen that, in the embodiment of the present application, before the AP device is configured, the number of AP devices having the same manufacturer and model as the AP device and AP devices having the same manufacturer and model as the AP device in the network system is determined by the built device discovery message. In this way, the number of segments of the image file and the configuration mode are determined conveniently.
Step S103: determining a target segment file required to be stored by the equipment and a segment sequence number of the target segment file according to a preset allocation rule; the target segment file is one of the segment files in the mirror image file.
After determining the number of segments of the image file, determining the target segment file and the segment sequence number of the target segment file which are required to be stored by the device according to a pre-configured allocation rule.
In one embodiment, the pre-formulated allocation rules include: determining the segment sequence number of each segment file in turn according to the segment number of the image file; and sequentially determining the segment files required to be stored by the AP equipment with the same manufacturer and model and the segment serial numbers of the segment files according to the size sequence of the MAC addresses of the AP equipment with the same manufacturer and model. The determined sectional files and sectional serial numbers of the sectional files which are required to be stored by the AP equipment with the same manufacturer and model comprise target sectional files and sectional serial numbers of the target sectional files which are required to be stored by the equipment.
The number of the AP devices with the same manufacturer and model number as the AP devices in the network system is four, and the number of the determined image files is four. Firstly, each sectional file is marked in sequence according to the file sequence of the image file, for example, the sectional sequence number of the first sectional file is 1, the sectional sequence number of the second sectional file is 2, the sectional sequence number of the third sectional file is 3, and the sectional sequence number of the fourth sectional file is 4 according to the file sequence of the image file.
And then sequentially determining the segment files required to be stored by the AP equipment with the same manufacturer and model and the segment serial numbers of the segment files according to the size sequence of the MAC addresses of the AP equipment with the same manufacturer and model. The order of the MAC addresses of the AP devices may be from small to large, or from large to small, which is not limited in this application. Taking four AP devices in table one as an example, the four AP devices are AP1, AP2, AP3 and AP4 in order of order from small to large according to MAC addresses. The segment file to be stored by AP1 is the segment file with the segment sequence number 1, the segment file to be stored by AP2 is the segment file with the segment sequence number 2, the segment file to be stored by AP3 is the segment file with the segment sequence number 3, and the segment file to be stored by AP4 is the segment file with the segment sequence number 4.
Assuming that the device is AP1, the target segment file determined in the mode is a segment file with the segment sequence number of 1.
In addition, if the number of segments of the image file is half of the number of AP devices with the same manufacturer and model as the AP devices in the network system, the segment files and the segment numbers of the segment files that need to be stored by the AP devices with the same manufacturer and model may also be determined according to the above rule.
The number of the AP devices with the same manufacturer and model number as the AP devices in the network system is four, and the number of the segments of the determined image files is two. Firstly, each segmented file is marked in sequence according to the file sequence of the image file, for example, the segment sequence number of the first segmented file is 1 and the segment sequence number of the second segmented file is 2 according to the file sequence of the image file.
And then sequentially determining the segment files required to be stored by the AP equipment with the same manufacturer and model and the segment serial numbers of the segment files according to the size sequence of the MAC addresses of the AP equipment with the same manufacturer and model. Taking four AP devices in table one as an example, the four AP devices are AP1, AP2, AP3 and AP4 in order of order from small to large according to MAC addresses.
In one case, each segment file is sequentially stored in one AP device according to the order of the sizes of the MAC addresses. If the segment file to be stored in the AP1 is a segment file with a segment number of 1, the segment file to be stored in the AP2 is a segment file with a segment number of 2. The remaining AP devices then store the segmented files from small to large as backup. The segmented file required to be stored by the AP3 is a segmented file with a segmented sequence number of 1, and the segmented file required to be stored by the AP4 is a segmented file with a segmented sequence number of 2.
In another case, each segment file is sequentially stored in two AP devices according to the order of the sizes of the MAC addresses. If the segment files required to be stored by AP1 and AP2 are segment files with segment number 1, and the segment files required to be stored by AP3 and AP4 are segment files with segment number 2.
It can be seen that in the embodiment of the present application, the reasonable allocation of the segment files is achieved through the order of the size of the MAC address of each AP device.
Of course, in other embodiments, the allocation rule may be configured according to the size of the IP address, which is not limited in this application.
Step S104: storing the target segment file, the segment sequence number of the target segment file and the segment number of the mirror image file into a nonvolatile memory of the device.
And finally, the equipment can store the determined target segment file, the segment sequence number of the target segment file and the segment number of the mirror image file into a nonvolatile memory of the equipment.
Of course, the nonvolatile memory of the device may also store information such as manufacturer, model, version number corresponding to the image file, etc.
In addition, the device may also perform CRC check on the target segment file before storing the target segment file. Correspondingly, the nonvolatile memory of the device can also store the CRC check value of the target segment file and/or the CRC check value of the whole mirror image file.
It should be noted that, each AP device in the network system may process the image file according to the above steps, so that it only needs to store one of the segmented files in the image file.
In summary, in the embodiment of the present application, after acquiring an image file of a system version to be configured, an AP device determines, according to the AP device in the network system that is the same as its manufacturer and model, the number of segments of the image file, and then determines, according to a preset allocation rule, a target segment file and a segment sequence number of the target segment file that need to be stored in a nonvolatile memory of the device. By the method, a complete image file can be respectively stored in the AP equipment with the same manufacturer and model of the network system, namely the AP equipment does not need to store the complete image file, and the non-volatile memory also stores the segment serial numbers of the segment files and the segment numbers of the image files, so that the non-stored segment files can be conveniently obtained from the AP equipment with the same manufacturer and model. It can be seen that this approach can realize more functional configuration requirements without increasing the hardware cost of the AP device.
After the storage of the target segment file is completed, the device can upgrade the system version based on the stored target segment file. The upgrading process of the system version is described below. Referring to fig. 4, the method further includes: step S201 to step S203.
Step S201: constructing a plurality of version upgrading request messages based on the number of the segment files which are not stored by the equipment; wherein, each version upgrade request message comprises a segment sequence number of an unrecorded segment file.
After the device stores the target segmented files, the device can sequentially request the AP devices with the same manufacturer and model as the device in the network system to acquire other segmented files, thereby realizing the upgrading of the system version.
Specifically, the device constructs a plurality of version upgrade request messages based on the number of the segment files that are not stored. The number of the AP devices with the same manufacturer and model number as the device in the network system is four, the determined number of the segments of the image file is also four, the segment sequence number of the target segment file is 1, then the device can construct three version upgrade request messages, and the segment sequence numbers carried by the three version upgrade request messages are respectively 2, 3 and 4.
In addition, the version upgrade request message may also include information such as manufacturer, model, version number corresponding to the image file, CRC check value of the segment file, and/or CRC check value of the whole image file, which is not limited in this application.
Step S202: and sequentially sending the version upgrading request message to the AP equipment with the same manufacturer and model as the equipment in the network system to acquire the segment file corresponding to the segment serial number of the segment file which is not stored.
After the version upgrading request message is constructed, the version upgrading request message is sequentially sent to the AP equipment with the same manufacturer and model as the equipment in the network system. For example, taking four AP devices in table one as an example, assuming that the device is AP1, AP1 may first send a version upgrade request message carrying segment number 2 to AP2. After receiving the version upgrading request message, the AP2 determines whether the version upgrading request message contains a segment file with the segment number of 2, and if so, the AP2 sends the segment file with the segment number of 2 to the AP1. After the AP1 obtains the segment file with the segment number 2, the version upgrade request message carrying the segment number 2 may not be sent to the AP 3. If the AP2 does not include the segment file with the segment number of 2, the AP1 sends the segment file with the segment number of 2 to the AP3, and so on, until the segment file with the segment number of 2 is obtained. And the AP1 sequentially sends version upgrading request messages carrying the segment number 3 to other AP equipment after acquiring the segment file with the segment number 2 until acquiring the segment file with the segment number 3.
In addition, when transmitting the segmented file, the message carrying the segmented file may also include information such as manufacturer, model, version number corresponding to the image file, CRC check value of the segmented file, and/or CRC check value of the whole image file. Correspondingly, when the device receives the segmented file, CRC check can be performed, then the CRC check value of the device check is compared with the CRC check value of the segmented file in the message transmitted by other devices, and if the comparison is passed, the segmented file is represented without errors.
In addition, after receiving the version upgrade request message, other AP devices may also verify whether the manufacturer and model carried by the version upgrade request message are consistent with the AP devices themselves, which is not limited in this application.
Step S203: and after all the segmented files of the image file are acquired, carrying out version upgrading on the equipment.
After all the segment files of the image file are obtained, the image file is stored to finish upgrading the version.
In addition, the upgrade process of AP2, AP3, and AP4 is the same as the upgrade process of AP1, and the same parts are referred to each other, which will not be described in detail.
It can be seen that, in this embodiment of the present application, the AP device constructs a plurality of version upgrade request packets based on the number of segment files that are not stored in the AP device, and then sequentially sends the version upgrade request packets to the AP device that has the same manufacturer and model as the AP device itself in the network system, so as to obtain the non-stored segment files, and finally, when all the segment files are obtained, version upgrade is implemented. It can be seen that this way, in the case that the image file is stored in different AP devices in a segmented manner, an effective upgrade of each AP device can be achieved.
In other embodiments, the version upgrade request message constructed by the AP device may also include the segment numbers of all the non-stored segment files at the same time. After receiving the version upgrading request message, other AP equipment only needs to determine whether the AP equipment contains the segment sequence number of any one segment file. If other AP equipment contains the segment sequence number of any one of the segment files, the AP equipment which sends the version upgrading request message is transmitted to the segment files.
The start-up procedure of the AP device is explained below. Referring to fig. 5, the image file configuration method may further include: step S301 to step S305.
Step S301: constructing a segmented information request message; the segmentation information request message comprises a manufacturer, a model number, a version number and a segmentation number.
When the device is started, whether the image file is segmented can be judged firstly, for example, whether the image file is segmented is judged according to the segmentation number of the storage image file, and if the segmentation number is greater than 1, the image file is segmented. At this time, a segment information request message is constructed.
In other embodiments, the segment information request message may further include a CRC check value of the image file.
Step S302: broadcasting the segment information request message to enable other AP equipment in the network system to receive the segment information request message.
Then, the present apparatus broadcasts the segment information request message. After receiving the segment information request message, the AP equipment in the network system judges whether the manufacturer, the model and the version number are consistent with the AP equipment, and if not, the AP equipment discards the message. If the two types of the storage media are consistent, constructing a segmentation information message, wherein the segmentation information message carries manufacturer, model, version number, segmentation number and the segmentation serial number of the stored segmentation file.
In addition, when the segmentation information request message includes the CRC check value of the image file, the AP equipment in the network system can also judge whether the CRC check value of the image file in the segmentation information request message is consistent with the CRC check value of the image file stored by the AP equipment in the network system after receiving the segmentation information request message, and if not, the AP equipment discards the message. If the two messages are consistent, constructing a segment information message.
Step S303: receiving segmentation information messages sent by other AP equipment; other AP equipment and the equipment have the same manufacturer, model number, version number and segmentation number; the segmentation information message comprises manufacturer, model, version number, segmentation number and the segmentation serial number of the stored segmentation file.
In addition, the segment information message may further include a CRC check value corresponding to the segment file and a CRC check value of the mirror image file. After receiving the segment information message, the device may also perform CRC check on the segment file again, and since this process has already been described in the foregoing embodiments, details are not repeated here.
Step S304: and sending a segmented file request message to other AP equipment based on the segmented sequence number carried by the segmented information message so as to acquire segmented files stored by the other AP equipment.
Then, the device can send a segment file request message to other AP devices based on the segment sequence number carried by the segment information message, so as to obtain the segment file which is not stored in the device from the other AP devices.
It should be noted that, the present device may sequentially request the corresponding segment files from other AP devices according to the sequence of the segment numbers. Assuming that the equipment is AP1, the segmentation serial number of the target segmentation file stored by the AP1 is 1, constructing a segmentation file request message carrying the segmentation serial number of 2, and then sending the segmentation file request message carrying the segmentation serial number of 2 to the corresponding AP equipment. Then, a segment file request message carrying the segment sequence number 3 is built again, and then the segment file request message carrying the segment sequence number 3 is sent to the corresponding AP equipment.
In addition, when transmitting the segmented file, the message carrying the segmented file may also include information such as manufacturer, model, version number corresponding to the image file, CRC check value of the segmented file, and/or CRC check value of the whole image file. Correspondingly, when the device receives the segmented file, CRC check can be performed, then the CRC check value of the device check is compared with the CRC check value of the segmented file in the message transmitted by other devices, and if the comparison is passed, the segmented file is represented without errors.
In addition, after receiving the segmented file request message, other AP devices can also verify whether the manufacturer, model, version number and CRC check value of the mirror image file carried by the segmented file request message are consistent with the CRC check value of the mirror image file. The present application is not limited in this regard.
Step S305: after all the segmented files of the image file are acquired, the system is started based on the image file formed by splicing all the segmented files.
After the device acquires all the segmented files of the image file, all the segmented files are spliced, and then the image file starting system formed based on the splicing of all the segmented files is started.
In addition, after the splicing is completed, CRC (cyclic redundancy check) can be performed on the spliced image files. If the verification is successful, the system is started, and if the verification is failed, the starting process is restarted.
It should be noted that the starting flow of other AP devices is the same as the present device. In addition, the device can respond to the request for acquiring the segmented file sent by other devices while acquiring the segmented file from other AP devices.
It can be seen that, in the embodiment of the present application, after the device is started, the AP device may construct a segment information request message; broadcasting the segmented information request message; then receiving segmented information messages sent by other AP equipment; transmitting a segmented file request message to other AP equipment based on the segmented sequence number carried by the segmented information message to acquire segmented files stored by the other AP equipment; after all the segmented files of the image file are acquired, the system is started based on the image file formed by splicing all the segmented files. Therefore, after the AP equipment is started, even if only one segmented file is stored in the nonvolatile memory, the normal starting of the system can be realized.
