Optionally, after receiving the shutdown message, the web service module in the master router may execute a lua script of shutdown, where the lua script may forward the shutdown message to a shutdown processing module of the master router, and further the shutdown processing module of the master router determines a shutdown order of the designated router selected by the user based on the shutdown message. Where lua is a scripting language.

S404, the main router sequentially controls the designated router selected by the user to be powered off according to the power-off sequence.

By adopting the method, the main router can receive the shutdown message sent by the terminal equipment, and the shutdown message is used for indicating the main router to shut down the appointed router selected by the user, that is, the user can select the appointed router to be shut down through the terminal equipment, and then the main router can determine the shutdown sequence of the appointed router selected by the user, so that the shutdown of the appointed router selected by the user is controlled according to the shutdown sequence. Therefore, when the user needs to close the designated router, the user does not need to find the geographical position of the designated router and switch off the power supply of the router by pressing a key, and the main router can automatically control the designated router selected by the user to switch off according to the determined switching-off sequence, so that the designated router can be switched off more conveniently and rapidly.

In some embodiments, the shutdown message includes an identification of the primary router, i.e., the shutdown message is used to indicate that the primary router is shutdown. In this case, the shutdown procedure of the master router is as shown in fig. 6.

Firstly, an APP or a web page of the terminal equipment sends a shutdown message to a web service module of the main router, wherein the shutdown message is a shutdown post request.

After receiving the shutdown message, the web service module calls a shutdown lua script, and sends the shutdown message to the shutdown processing module through the shutdown lua script.

And the shutdown processing module processes the shutdown message, and after recognizing that the shutdown message is used for indicating to close the main router, the shutdown processing module can call the configuration service module, and the configuration service module can acquire the file lock.

If the acquisition is successful, returning a shutdown execution code to the shutdown processing module, and executing a shutdown function; if the acquisition fails, returning a shutdown execution code to the shutdown processing module.

If the file lock is successfully obtained, the current shutdown can be performed, and the returned shutdown execution code is used for indicating that the shutdown operation is successfully executed. If the file lock is not obtained, the returned shutdown execution code is used for indicating that shutdown cannot be performed at present. Optionally, if the file lock is not acquired, a current state parameter of the file lock may be acquired, for example, if the state parameter is 01, it indicates that an upgrade is currently performed; if the state parameter is 10, the current restart is indicated; if the status parameter is 11, it indicates that the factory setting is currently being restored. The primary router may determine a shutdown execution code based on the acquired state parameters.

As an example, the specific meaning of the shutdown execution code is shown in table 1.

TABLE 1

Shutdown execution code	Meaning of the concrete
		0	Successfully executing shutdown operation
100	Can not be shut down and is being upgraded
		101	Unable to shut down, restarting
102	Can not be shut down and is recovering from factory setting

Under the condition that the file lock is successfully acquired, the configuration service module can execute a shutdown function, and particularly can call the kernel so that the kernel stores the current application data of the main router, the kernel can call a shutdown interface which is driven to register in the kernel, and the pins corresponding to the GPIO numbers are pulled down according to the general purpose input/output port (General Purpose Input Output, GPIO) numbers corresponding to the shutdown interface, so that the main router can realize power-off shutdown.

Optionally, after the shutdown processing module obtains the shutdown execution code returned by the configuration service module, the shutdown execution code may be returned to the web service module, so that the web service module returns a shutdown result to the terminal device.

In other embodiments, the identity of the slave router is included in the shutdown message, i.e., the shutdown message is used to indicate that the slave router is shutdown. In this case, taking one of the slave routers as an example, the shutdown procedure for the slave router is shown in fig. 7.

Firstly, an APP or a web page of the terminal equipment sends a shutdown message to a web service module of the main router, wherein the shutdown message is a shutdown post request. After receiving the shutdown message, the web service module calls a shutdown lua script, and sends the shutdown message to the shutdown processing module through the shutdown lua script.

And the shutdown processing module processes the shutdown message, and after recognizing that the shutdown message is used for indicating to close the slave router, the shutdown processing module can send a shutdown instruction to the slave router.

After the shutdown processing module of the slave router receives the shutdown instruction, the processing of the shutdown instruction is performed, and the configuration service module can be specifically called, so that the configuration service module can acquire the file lock, and the subsequent specific shutdown process is basically the same as that of the configuration service module of the master router in the above embodiment, and is not described herein. The method is characterized in that after the shutdown processing module of the slave router receives the shutdown execution code, the message execution code is required to be returned to the shutdown processing module of the master router, so that the master router returns a shutdown result to the terminal equipment.

In some embodiments, if the identification of the master router is included in the shutdown message and the identification of the slave router is not included, then a shutdown operation to the master router is performed.

In some embodiments, in the case that the shutdown message includes an identifier designating the slave router, S403 may be implemented as follows: and sending a shutdown instruction to the designated slave router so that the designated slave router performs a shutdown operation in response to the shutdown instruction.

In some embodiments, in the case that the shutdown message includes the identities of the plurality of designated routers selected by the user, S403, the determining, by the master router, the shutdown order of the designated routers selected by the user may be specifically implemented as:

acquiring a hierarchy of each designated router in the plurality of designated routers from the master router based on the identifications of the plurality of designated routers; and ordering the plurality of designated routers according to the order of the hierarchy from low to high, and taking the ordering result as the shutdown order of the plurality of designated routers.

Optionally, if there are at least two designated routers with the same hierarchy in the plurality of designated routers, the at least two designated routers are ordered in the order from late to early access times. Alternatively, the at least two designated routers may be ordered in the order of the access time from early to late, or the shutdown order of the at least two designated routers may be randomly determined. Or the master router may not care about the access time of the designated router, if it is determined that at least two designated routers with the same hierarchy exist in the plurality of designated routers, it is determined that the shutdown orders of the at least two designated routers are the same, and then the shutdown instructions may be sent to the at least two designated routers at the same time.

It may be understood that the plurality of designated routers may be slave routers, or may include a slave router and a master router, where the level of the master router may be determined to be 0 when the plurality of designated routers includes the master router, that is, the shutdown sequence of the master router is arranged at the end, and after shutdown of the plurality of slave routers is completed according to the shutdown sequence, the master router is further required to be shutdown.

In the embodiment of the present application, the level of the designated router may be the hop count between the designated router and the master router, for example, in the scenario of fig. 5, the level of the slave router 1 is 1, the level of the slave router 3 is 2, and the level of the slave router 4 is 2.

Taking the scenario of fig. 5 as an example, the shutdown order determined by the master router is shown in table 2.

TABLE 2

Router	Hierarchy level	Access time	Shutdown sequence
				Slave router 1	1	1	3
Slave router 3	2	3	2
				Slave router 4	2	4	1

Since the hierarchy of the slave router 1 is lowest, the shutdown order of the slave router 1 is at the end. The slave router 3 and the slave router 4 have the same hierarchy, but the access time of the slave router 4 is later, it may be determined that the slave router 4 is turned off first and then the slave router 3 is turned off.

By adopting the embodiment of the application, as the hop count with the main router is smaller and the hierarchy is lower, the plurality of designated routers are ordered according to the sequence from low to high of the hierarchy, and the ordering result is used as the shutdown sequence of the plurality of designated routers, so that the problem that the routers with low hierarchy cannot receive the shutdown instruction sent by the main router due to the first shutdown of the routers with high hierarchy can be avoided, and the success rate of shutdown of the routers can be improved.

On the basis of the above embodiment, in one case, the plurality of designated routers selected by the user may include a slave router, and in order to enable the slave router in the plurality of designated routers to perform shutdown according to a shutdown order, S404 may be specifically implemented as follows:

Specifically, after the master router sends a shutdown instruction to one slave router according to the shutdown sequence, acquiring a shutdown result of the slave router, and after acquiring a shutdown result of the slave router, continuing to send a shutdown instruction to the next slave router according to the shutdown sequence; if a shutdown result of shutdown failure of any one slave router is received, stopping sending a shutdown instruction.

For example, according to the shutdown sequence table shown in table 2, the master router may send a shutdown instruction to the slave router 4 first, send a shutdown instruction to the slave router 3 after determining that the slave router 4 is shutdown successfully, and send a shutdown instruction to the slave router 1 after determining that the slave router 3 is shutdown successfully. In this way, it is avoided that router 1 is turned off first, resulting in router 1 not being able to forward a shutdown instruction to router 3 and router 4.

Therefore, the main router can control the specified routers to shut down according to the shutdown sequence, and users do not need to find the geographical positions of the specified routers respectively, so that the method is more convenient and faster.

In another case, if the plurality of designated routers selected by the user include the master router and the slave router, S404 may be specifically implemented as follows:

For example, if the shutdown sequence table in table 2 further includes a master router, and the level of the master router is 0, the shutdown operation may be performed on the master router after determining that the shutdown on the slave router 1 is successful according to the shutdown sequence on the slave router.

The shutdown processing module of the master router may call the configuration service module and execute the subsequent shutdown process, and the specific process may refer to the related description in the corresponding embodiment of fig. 6, which is not repeated herein.

By adopting the method, the user can control the plurality of slave routers and the master router to shut down according to the shutdown sequence by triggering the shutdown operation once, and the user does not need to find the geographical positions of the plurality of slave routers and the master router respectively, so that the method is more convenient and faster.

In some embodiments, after the master router sends a shutdown instruction to each slave router, the slave router may also receive a shutdown execution code sent by the slave router, and determine a shutdown result of the slave router based on the shutdown execution code. The shutdown specification code is used to indicate whether the slave router successfully performs the shutdown operation, and the description of the shutdown execution code may refer to the description of table 1 in the above embodiment, which is not repeated herein.

The method comprises the steps of determining a shutdown result of a slave router based on a shutdown execution code, and specifically comprises any one of the following three implementation modes.

The first mode is that if the shutdown execution code indicates that the shutdown operation is successfully executed, the shutdown result is determined to be shutdown success, otherwise, the shutdown result is determined to be shutdown failure. Therefore, the shutdown result can be conveniently and quickly determined.

For example, if the shutdown execution code is 0, it may be determined that shutdown was successful; if the shutdown execution code is not 0, the shutdown failure can be determined.

And if the shutdown execution code indicates that the shutdown operation is successfully executed, and the heartbeat packet from the slave router is not received within a preset time period after the shutdown execution code is received, determining that the shutdown result is successful, otherwise, determining that the shutdown result is failed.

For example, the preset duration may be 6 seconds, and if the received shutdown execution code is 0 and the heartbeat packet of the slave router is not received within 6 seconds after the shutdown execution code is received, it may be determined that the slave router is shutdown successfully.

Otherwise, if the shutdown execution code is not 0, or the heartbeat packet from the slave router is received within a preset time period after the shutdown execution code is received, determining that the slave router fails to shutdown.

The slave router can call the shutdown interface to execute shutdown operation while sending the shutdown execution code to the master router, if the shutdown operation is not successfully executed due to abnormal conditions, the slave router can continuously send a heartbeat packet to the master router, after the master router receives the shutdown execution code with the value of 0, if the heartbeat packet from the slave router is received within a preset duration, the slave router can be determined to fail in shutdown. Therefore, the shutdown result of the slave router is comprehensively judged through the shutdown execution code and the heartbeat packet of the slave router, so that the determined shutdown result is more accurate.

And if the shutdown execution code indicates that the shutdown operation is successfully executed, a notification message for indicating that the wired connection of the slave router is disconnected is received, and a heartbeat packet from the slave router is not received within a preset time period after the shutdown execution code is received, determining that the shutdown result is successful, otherwise, determining that the shutdown result is failed.

The third mode is applicable to the case that the access mode of the slave router is a wired connection. The notification message for indicating that the wired connection from the router has been disconnected may specifically be a lan down message.

If the master router and the slave router are connected through a wire, after the slave router is powered off and shut down, the driving layer of the master router can recognize that the slave router is powered off, and then the driving layer can report an lan down message to the application layer. The LAN down message is specifically a message which is reported by the portal driver and used for indicating (Local Area Network, LAN) that the portal has been switched to the down state after a router is powered off or the network cable connection is disconnected by a down-hanging router connected by a wire.

By adopting the third mode, whether the specified router is powered off successfully or not can be judged by integrating the power-off execution code, the lan down message and the heartbeat packet, and the determined power-off result can be more accurate.

In some embodiments, after determining the shutdown result of the slave router, the master router may send the shutdown result of the slave router to the terminal device, and then the terminal device displays the shutdown result. The shutdown result may be shutdown success or shutdown failure. And under the condition that the shutdown execution code indicates the shutdown failure and the reason of the shutdown failure, the shutdown result comprises the reason of the shutdown failure.

For example, if the shutdown execution code is 100, the shutdown result is shutdown failure, and the reason why shutdown cannot be performed is that the slave router is being upgraded. If the shutdown execution code is 101, the shutdown result is shutdown failure, and the reason why shutdown cannot be performed is that the slave router is restarting. If the shutdown execution code is 102, the shutdown result is shutdown failure, and the reason why shutdown is impossible is that the slave router is recovering from factory settings.

By adopting the method, the terminal equipment can display the shutdown result, so that a user can intuitively check the shutdown result through the terminal equipment, and if shutdown failure exists, the reason that shutdown cannot be performed can be known, the user experience is better, and the user can manage each router more conveniently.

It should be noted that, a heartbeat mechanism is provided between the master router and the slave router, that is, the slave router sends a heartbeat packet to the master router once every fixed time interval, if the master router does not receive the heartbeat packet of the slave router within a specified time period, the master router determines that the slave router has been disconnected from the power supply.

As an alternative implementation manner, after receiving the shutdown instruction, the slave router may shorten a fixed time interval for sending the heartbeat packet to the master router if it is determined that the shutdown operation can be currently performed by acquiring the file lock. For example, the heartbeat packet may be transmitted from every one minute, and the heartbeat packet may be transmitted at every 2 seconds. Therefore, the master router can timely determine whether the slave router is successfully powered off or not, and timely feed back the power-off result to the terminal equipment, so that a user can quickly know the power-off result, and user experience is improved.

S814, the slave router 1 forwards the shutdown execution code and the lan down message to the master router.

The slave router 3 and the slave router 1 are connected by a wired connection mode, and after the slave router 3 is shut down, the driving layer of the slave router 1 reports an lan down message to the application layer, and the slave router 1 forwards the lan down message to the master router.

S820, the master router receives the lan down message and determines that the heartbeat message of the slave router 1 is not received within a preset duration.
