Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring 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). 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 files belong to running system files, and with the continuous development of Wireless Local Area Network (WLAN) technology, the technology is more and more complex, the functions are more and more, and the image files of the AP device are also more and more large.

However, if the cost of the AP device is to be controlled, only part of the functional requirements are sacrificed. Therefore, the configuration mode of the current AP device cannot meet the configuration requirements of lower cost and more functions at the same time.

In addition, the AP equipment also comprises a nonvolatile flash memory, and a certain segmented file after the image file is segmented is stored in the nonvolatile flash memory.
It should be noted that the structure shown in fig. 2 is merely an illustration, and the AP device 100 provided in the embodiment of the present application may also have fewer or more components than those in fig. 2, or have a different configuration from that shown in fig. 2. 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 configuring 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 image file configuration method 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: and acquiring the image file of the system version to be configured.
The AP device may log in an AP page or a command interface in any manner such as a Web, an SSh (secure shell protocol), a Telnet (remote terminal protocol), and a serial port to receive a mirror image file of the system version to be configured. The image file of the system version to be configured may be an image file of the system version to be upgraded, or an image file of the AP device when the AP device is configured for the first time. That is, step S101 may be executed when the AP device upgrades the system version, or may be executed when the AP device configures the image file for the first time.
After the AP device obtains the image file of the system version to be configured, the AP device may download the image file to the local memory.
In an embodiment, after acquiring the image file of the system version to be configured, the AP device also acquires a CRC check value of the image file. Correspondingly, the AP device may further perform a Cyclic Redundancy Check (CRC) Check on the image file, and then determine whether the image file is error-free by comparing whether a CRC Check value obtained by the self Check is consistent with the obtained CRC Check value. When the CRC value obtained by self-checking is consistent with the acquired CRC value, the image file is represented to be correct, and then the subsequent steps are executed. When the CRC value obtained by self-checking is inconsistent with the obtained CRC value, the representation image file is wrong, and at the moment, the AP equipment can obtain the image file of the system version to be configured again.
Since CRC checking is a well-known checking method in the art, the present application does not give much description.
Step S102: determining the number of segments of the image file according to the number of the AP devices with the same manufacturer and model as the AP devices in the network system acquired in advance; the number of the segments of the image file is not more than the number of AP devices with the same manufacturer and model as the AP device in the network system.
Note that, when counting the number of AP devices having the same manufacturer and model as the own device, it is necessary to count itself. For example, the manufacturer of the device is V1 and the model is X1. The network system further includes three AP devices with a vendor of V1 and a model of X1, and the number of the AP devices with the same vendor and model as the present device in the network system is four.
In step S102, when acquiring the image file, the AP device determines the number of segments of the image file according to the number of pre-acquired AP devices having the same manufacturer and model as the AP device in the network system.
In one 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 AP device.
Illustratively, if the number of AP devices having the same manufacturer and model as the present device in the network system is four, the number of segments of the image file is four. I.e. the image file is divided into four segment files.
In another embodiment, the number of segments of the image file is half of the number of AP devices in the network system having the same manufacturer and model as the AP device.
Illustratively, if the number of AP devices having the same manufacturer and model as the present device in the network system is four, the number of segments of the image file is two. I.e. the image file is split into two fragmented files.
It should be noted that, when the number of segments of the image file is half of the number of AP devices in the network system having the same manufacturer and model as the device, the same segment file may be subsequently stored in two AP devices at the same time, and then backup of one segment file is completed.
It should be noted that the minimum unit of the segmented file is 64Kb (kilobyte) or 128Kb (which is determined by the minimum read-write unit of the nonvolatile flash memory device).
In this embodiment of the present application, the obtaining of the AP device having the same manufacturer and model as the AP device in the network system through the following steps includes: constructing a device discovery message; the equipment discovery message comprises a manufacturer, a model and an equipment address; broadcasting the device discovery message so that other AP devices in the network system receive the device discovery message; receiving device response messages sent by other AP devices; the 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 equipment with the same manufacturer and model as the equipment and the number of the AP equipment with the same manufacturer and model as the equipment based on the equipment response message.
The above-mentioned process of acquiring the AP device having the same manufacturer and model as the present device in the network system may be performed before performing step S101. 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 the AP device logs in, the AP device performs a device search operation. Firstly, an equipment discovery message is constructed, and the message carries the manufacturer, the model and the equipment address of the message. The device address may include an IP (Internet Protocol) address and/or a MAC (Media Access control address) address. The device discovery message may be, but is not limited to, a UDP (User data packet Protocol) message. Then, the AP device broadcasts the message through the network. After receiving the device discovery message, other AP devices in the network parse the device discovery message, and then determine whether the manufacturer and model carried in the message are consistent with the AP device, and if not, discard the message. And if so, the AP equipment constructs an equipment response message to reply the AP equipment which sends the equipment discovery message. 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 number of AP devices having the same manufacturer and model as the device and the number of AP devices having 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.
Watch 1
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 having the same manufacturer and model as the device in the network system is four (i.e., AP1, AP2, AP3, and AP 4).
It can be seen that, in the embodiment of the present application, before configuration, the AP device determines, through the device discovery packet that is constructed, the number of AP devices in the network system that have the same manufacturer and model as the AP device and the number of AP devices that have the same manufacturer and model as the AP device. By the method, the number of the segments of the image file and the configuration mode can be determined conveniently in the follow-up process.
Step S103: determining a target segmented file required to be stored by the equipment and a segmented sequence number of the target segmented file according to a pre-configured distribution rule; the target segmented file is one of the segmented files in the mirror image file.
After the number of the segments of the image file is determined, the target segment file and the segment sequence number of the target segment file, which are required to be stored by the device, can be determined according to the pre-configured distribution rule.
In one embodiment, the pre-formulated allocation rules include: determining the segment sequence number of each segment file in sequence according to the segment number of the mirror image files; and sequentially determining the segmented files required to be stored by the AP equipment with the same manufacturer and model and the segmented serial numbers of the segmented files according to the size sequence of the MAC addresses of the AP equipment with the same manufacturer and model. The determined segmented files required to be stored by the AP equipment with the same manufacturer and model and the segmented sequence numbers of the segmented files comprise target segmented files required to be stored by the equipment and the segmented sequence numbers of the target segmented files.
Illustratively, the number of AP devices having the same manufacturer and model as the device in the network system is four, and the number of segments of the determined image file is also four. Firstly, according to the file sequence of the mirror image file, each segmented file is marked in sequence, for example, according to the file sequence of the mirror image file, the segment sequence number of the first segmented file is 1, the segment sequence number of the second segmented file is 2, the segment sequence number of the third segmented file is 3, and the segment sequence number of the fourth segmented file is 4.
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 MAC addresses of the AP devices may be in a descending order or a descending order, which is not limited in this application. Taking the four AP devices in table one as an example, the four AP devices are AP1, AP2, AP3 and AP4 in order of descending MAC addresses. The segment file required to be stored by the AP1 is the segment file with segment sequence number 1, the segment file required to be stored by the AP2 is the segment file with segment sequence number 2, the segment file required to be stored by the AP3 is the segment file with segment sequence number 3, and the segment file required to be stored by the AP4 is the segment file with segment sequence number 4.
Assuming that the device is AP1, the target segment file determined in this way is a segment file with a segment sequence number of 1.
In addition, if 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 segment file and the segment number of the segment file, which are required to be stored by the AP device having the same manufacturer and model, may also be determined according to the above rules.
Illustratively, the number of the AP devices having the same manufacturer and model as the device in the network system is four, and the number of the determined segments of the image file is two. Firstly, according to the file sequence of the mirror image file, each segment file is marked in sequence, for example, the segment sequence number of the first segment file is 1, and the segment sequence number of the second segment file is 2 according to the file sequence of the mirror 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 the four AP devices in table one as an example, the four AP devices are AP1, AP2, AP3 and AP4 in order of descending MAC addresses.
In one case, each of the fragmented files is sequentially stored in one AP device according to the size order of the MAC addresses. If the segment file required to be stored by the AP1 is a segment file with a segment sequence number of 1, and the segment file required to be stored by the AP2 is a segment file with a segment sequence number of 2. The remaining AP devices then store the segmented file from small to large as a backup. The segment file required to be stored by the AP3 is a segment file with a segment sequence number of 1, and the segment file required to be stored by the AP4 is a segment file with a segment sequence number of 2.
In another case, each segment file is sequentially stored in two AP devices according to the size order of MAC addresses. The segment files required to be stored as AP1 and AP2 are segment files with segment sequence number 1, and the segment files required to be stored as AP3 and AP4 are segment files with segment sequence number 2.
It can be seen that in the embodiment of the present application, reasonable allocation of the segment files is achieved through the size order of the MAC addresses of each AP device.
Of course, in other embodiments, the allocation rule may also be configured according to the size of the IP address, which is not limited in this application.
Step S104: and storing the target segmented file, the segmented serial number of the target segmented file and the segmented number of the mirror image file into a nonvolatile memory of the equipment.
And finally, the equipment can store the determined target segmented file, the segmented serial number of the target segmented file and the segmented number of the mirror image file into a nonvolatile memory of the equipment.
Certainly, the nonvolatile memory of the device may also store information such as manufacturer, model, version number corresponding to the image file, and the like.
In addition, the device can also perform CRC check on the target segmented file before storing the target segmented file. Correspondingly, the nonvolatile memory of the device can also store the CRC value of the target segmented file and/or the CRC value of the whole 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 only one of the segment files in the image file needs to be stored.
In summary, in the embodiment of the present application, after acquiring the image file of the system version to be configured, the AP device determines the number of segments of the image file according to the AP device having the same manufacturer and model as the AP device in the network system, and then determines the target segment file to be stored in the nonvolatile memory of the AP device and the segment number of the target segment file according to the pre-configured allocation rule. By the method, a complete image file can be respectively stored in the AP equipment with the same manufacturer and the same 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 number of the segment file and the segment number of the image file, so that the non-stored segment file can be conveniently acquired from other AP equipment with the same manufacturer and the same model in the subsequent process. Therefore, the mode can meet the configuration requirement of more functions on the basis of not increasing the hardware cost of the AP equipment.
After the device finishes the storage of the target segmented file, the device can carry out system version upgrading based on the stored target segmented file. The following describes the upgrading process of the system version. 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 in the device; each version upgrading request message comprises a segment sequence number of an prestored segment file.
After the device stores the target segmented file of the device, 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, and then upgrade of the system version is realized.
Specifically, the device constructs a plurality of version upgrade request messages based on the number of the segment files that are not stored. Illustratively, the number of AP devices having the same manufacturer and model as the device in the network system is four, the number of segments of the determined image file is also four, and the segment number of the target segment file is 1, then the device will construct three version upgrade request messages, where the segment numbers carried in the three version upgrade request messages are 2, 3, and 4, respectively.
In addition, the version upgrade request message may also include information such as a manufacturer, a model, a version number corresponding to the image file, a CRC check value of the segment file, and/or a CRC check value of the entire image file, which is not limited in this application.
Step S202: and sequentially sending the version upgrading request message to AP (access point) equipment with the same manufacturer and model as the equipment in the network system so as to acquire the segmented files corresponding to the segmented serial numbers of the non-stored segmented files.
After the version upgrading request message is constructed, the version upgrading request message is sequentially sent to AP equipment with the same manufacturer and model as the AP 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 sequence number 2 to AP 2. After receiving the version upgrade request message, the AP2 determines whether the AP itself includes the segment file with the segment sequence number 2, and if so, sends the segment file with the segment sequence number 2 to the AP 1. After acquiring the segment file with the segment sequence number of 2, the AP1 may not send the version upgrade request message with the segment sequence number of 2 to the AP 3. If the AP2 does not contain the segment file with the segment sequence number 2, the AP1 sends the segment file with the segment sequence number 2 to the AP3, and so on until the segment file with the segment sequence number 2 is obtained. After acquiring the segment file with the segment sequence number of 2, the AP1 sequentially sends version upgrade request messages with the segment sequence number of 3 to other AP devices until acquiring the segment file with the segment sequence number of 3.
In addition, when the other AP devices transmit the segment file, the message carrying the segment file may also include information such as a manufacturer, a model, a version number corresponding to the image file, a CRC check value of the segment file, and/or a CRC check value of the entire image file. Correspondingly, when the device receives the segmented file, the device can also perform CRC check, then the CRC check value of the device per se 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 to be correct.
In addition, after receiving the version upgrade request message, the other AP devices may also verify whether the manufacturer and the model carried in the version upgrade request message are consistent with themselves, which is not limited in this application.
Step S203: and after all the segmented files of the image file are obtained, version upgrading is carried out on the equipment.
After all the segmented files of the image file are acquired, the image file is stored to finish the upgrading of the version.
In addition, the upgrading processes of the AP2, the AP3, and the AP4 are the same as the upgrading process of the AP1, and the same parts may be referred to each other, which is not described in detail herein.
As can be seen, in the embodiment of the present application, the AP device constructs a plurality of version upgrade request messages based on the number of the segment files that are not stored in the AP device, and then sequentially sends the version upgrade request messages to the AP devices having the same manufacturer and model as the AP device in the network system, so as to obtain the segment files that are not stored, and finally obtains all the segment files, thereby implementing version upgrade. Therefore, the method can realize effective upgrading of each AP device under the condition that the image file is stored in different AP devices in a sectional mode.
In other embodiments, the version-up request packet constructed by the AP device may also include segment sequence numbers of all the segment files that are not stored. After receiving the version upgrade request message, the other AP devices only need to determine whether they contain the segment sequence number of any one of the segment files. And if the other AP equipment contains the segment serial number of any one of the segment files, transmitting the segment file to the AP equipment which sends the version upgrading request message.
The following describes a startup procedure of the AP device. Referring to fig. 5, the method for configuring the image file may further include: step S301 to step S305.
Step S301: constructing a segmented information request message; the segment information request message includes a manufacturer, a model, a version number and a segment number.
When the device is started, whether the image file is segmented or not can be judged firstly, for example, whether the image file is segmented or not is judged according to the number of segments of the stored image file, and if the number of segments 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: and broadcasting the segment information request message so that other AP equipment in the network system receives the segment information request message.
Then, the device broadcasts the segment information request message. After receiving the segment information request message, the AP device in the network system determines whether the manufacturer, model, and version number are consistent with itself, and if not, discards the message. And if the two files are consistent, constructing a segmented information message, wherein the segmented information message carries manufacturers, models, version numbers, segment numbers and segment serial numbers of the stored segmented files.
In addition, when the segment information request message includes the CRC value of the image file, after receiving the segment information request message, the AP device in the network system may further determine whether the CRC value of the image file in the segment information request message is consistent with the CRC value of the image file stored in the AP device, and if not, discard the message. And if the two messages are consistent, constructing a segmented information message.
Step S303: receiving a segmented information message sent by other AP equipment; the other AP equipment and the equipment have the same manufacturer, model, version number and segmentation quantity; the segment information message includes manufacturer, model, version number, segment number and segment serial number of the stored segment file.
In addition, the segment information packet may further include a CRC check value corresponding to the segment file and a CRC check value of the image file. After receiving the segment information packet, the device may also perform CRC check on the segment file again, which is not described herein since the process has been described in the foregoing embodiments.
Step S304: and sending a segment file request message to other AP equipment based on the segment sequence number carried by the segment information message to acquire the segment file stored by other AP equipment.
Then, the device may send a segment file request message to other AP devices based on the segment sequence number carried in the segment information message, and further obtain the segment file that is not stored in the device from 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 size sequence of the segment sequence numbers. Assuming that the device is AP1 and the segment sequence number of the target segment file stored in AP1 itself is 1, a segment file request message carrying segment sequence number 2 is first constructed, and then a segment file request message carrying segment sequence number 2 is sent to the corresponding AP device. Then, a segment file request message carrying a segment sequence number of 3 is constructed, and then the segment file request message carrying the segment sequence number of 3 is sent to the corresponding AP equipment.
In addition, when the other AP devices transmit the segment file, the message carrying the segment file may also include information such as a manufacturer, a model, a version number corresponding to the image file, a CRC check value of the segment file, and/or a CRC check value of the entire image file. Correspondingly, when the device receives the segmented file, the device can also perform CRC check, then the CRC check value of the device per se 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 to be correct.
In addition, after receiving the segment file request message, other AP devices may also verify whether the manufacturer, model, version number, and CRC check value of the image file carried in the segment file request message are consistent with themselves. The present application is not limited to this.
Step S305: and after all the sectional files of the image file are obtained, starting the system based on the image file formed by splicing all the sectional files.
After the device obtains all the segmented files of the image file, all the segmented files are spliced, and then the system is started based on the image file formed by splicing all the segmented files.
In addition, after splicing is completed, CRC (cyclic redundancy check) can be carried out on the spliced mirror image file. If the verification is successful, the system is started, and if the verification is failed, the starting process is re-entered.
It should be noted that the startup procedure of other AP devices is the same as that of the present device. In addition, the device may also respond to a request for acquiring the segment file sent by another device while acquiring the segment file from another AP device.
Therefore, in the embodiment of the application, after the device is started, the AP device may construct a segment information request message; broadcasting the segment information request message; then receiving the segmented information message sent by other AP equipment; sending a segment file request message to other AP equipment based on the segment sequence number carried by the segment information message to acquire segment files stored by other AP equipment; and after all the sectional files of the image file are obtained, starting the system based on the image file formed by splicing all the sectional 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.
