[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] It should be noted that, if there is no conflict, the various features in the embodiments of the present application can be combined with each other, all within the scope of protection of the present application. In addition, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in a different order than the module division in the device schematic diagram or the order in the flow chart.

[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0030] Remote Wake-on-LAN (RWoL) is a technology for remotely starting a computer via a network. It is an expansion and improvement of the Wake-on-LAN (WoL) technology, providing a more flexible and powerful remote wake-up function. Traditional remote network wake-up computer technology is to send a specific network data packet through a remote device with network function (such as a mobile phone, computer), which contains the MAC address of the target computer and the wake-up command. The sent network data packet is transmitted to the target computer device through the local area network and / or wide area network. The network card of the target computer device will monitor the data packet on the network and identify it according to the MAC address contained in the network data packet. When the MAC address of the target computer device is matched, the network card of the target computer device will trigger the system wake-up process, so that the target computer device switches from the shutdown or standby state to the startup state.

[0031] When waking up a computer device using the above-mentioned remote network wake-up computer technology, it is usually not possible to directly select the system image on the target computer device, but the default system image is loaded according to the preset boot order. This means that it is not possible to remotely wake up the target computer device and directly select a specific system image to use. For example, suppose there are two different system images on the target computer device: Windows 10 and Ubuntu Linux. By default, the target computer device is set to load the Windows 10 system image first and then the Ubuntu Linux system image according to the boot order. Under this setting, if the computer device is woken up from the shutdown state using the remote network wake-up computer technology, it will automatically load the default Windows 10 system image, and it is not possible to directly select to load the Ubuntu Linux system image, because the awakened computer device will load the system image in the preset order.

[0032] Therefore, the existing remote network wake-up target computer device solution cannot flexibly select the system image to be started, which limits the flexibility of the user in selecting and operating the system image on the target computer device.

[0033] Based on this, the inventor provides a network wake-up mirror switching method, device, system and electronic device, which can not only realize remote wake-up of the target device and boot into the system mirror, but also enable the target device to boot into the specified system mirror.

[0034] The network wake-up mirror switching system of the embodiment of the present application is described below through specific embodiments.

[0035] See also Figure 1 and Figure 2 , Figure 1 is a system architecture diagram of a network wake-up mirror switching system provided in an embodiment of the present application, Figure 2 1 is a timing diagram of a network wake-up mirror switching system provided by an embodiment of the present application when performing a network wake-up mirror switching operation. Figure 1 As shown, the network wake-up mirror switching system includes: a front end 10, a back end 20, a first client 30 and a second client 40. The front end 10 is connected to the back end 20 via a network, the first client 30 and the second client 40 are also connected to the back end 20 via a network, and the first client 30 and the second client 40 are also connected to each other via a network.

[0036] The front end 10 provides an interactive method for generating switching image instructions through client tools such as mobile applications, mobile clients, and browsers, so that users can generate target switching image instructions according to specific image switching requirements. It can be understood that Figure 1 The front end 10 is merely illustrative, and the front end 10 may be a mobile communication device (such as a smart phone, a multimedia phone, a functional phone, etc.), an ultra-mobile personal computer device (such as a PDA, a MID, and a UMPC device, etc.), a portable entertainment device (such as an audio and video player, a handheld game console, a smart toy, and a portable vehicle navigation device, etc.). For example, a target mobile client for network wake-up mirror switching is installed on a certain mobile terminal, and the user interacts with the target mobile client on the mobile terminal to generate a target switching mirror command that wakes up a certain remote target computer device and switches to the Linux system. Figure 2 As shown, when a network wake-up mirror switching operation is performed, the front end 10 is used to send a mirror switching instruction to the back end 20.

[0037] The backend 20 may be a server, which may be an independent server or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms. Figure 2 As shown, when a network wake-up mirror switching operation is performed, the back end 20 is used to send a wake-up instruction to the first client 30 according to the switching mirror instruction.

[0038] When the network wake-up mirror switching system is started, all client devices (such as Figure 1 The first client 30 and the second client 40 in the example can upload their own MAC addresses to the backend 20, so that the backend 20 can uniformly manage all clients that can be awakened by the network. In addition, other software and hardware information (such as CPU model, motherboard model, user-defined client device name, etc.) that can be used for identity identification of all client devices can also be uploaded, so that each client device can be distinguished and managed from other client devices.

[0039] Optionally, what is uploaded together with the MAC address of the client device may also include the network structure of all client devices (for example, the subnet where a target client device is located, and the network path from the back end 20 to the target client device), so that the generated control instructions can be transmitted to all client devices through the network structure.

[0040] Optionally, what is uploaded together with the MAC address of the client device may also include all computer system images installed on the client device, and the system information of the computer system images. When multiple computer system images (such as Windows system images, Linux system images, MacOS system images, Unix system images, etc.) are installed on the client device, it is possible to switch between multiple computer system images. Among them, it should be specially noted that there are cases where the same type of computer system images are installed on the client device. For example, three Windows system images are installed on a certain target client at the same time (the first one is Windows 10, the second one is also Windows 10, and the third one is Windows 7). At this time, it is necessary to distinguish them according to the system information of the computer system images, such as system labels or descriptions, or system boot order, or system disk location, etc.

[0041] Optionally, after receiving the MAC addresses, network structures, installed computer system images, and system information of the computer system images of all the above-mentioned client devices, the back end 20 generates a client information interface that provides access to client device information, so that the front end 10 can obtain the MAC addresses, installed computer system images, and system information of the computer system images of the client devices according to the client interface. Among them, in some more embodiments, the security of the network wake-up image switching system can be further improved, because the network structure of all client devices is used for client management by the back end device, and the network structure can be hidden from the front end 10, that is, the network structure is not added to the client information interface, further avoiding the risk of leakage of the network structure.

[0042] Optionally, when each front end 10 accesses the back end 20 through the client information interface, the back end 20 may also check the authority of each user logged in on the front end 10, and the back end 20 may only return the client device to which the logged in user has authority. The authority of the logged in user is determined when the front end 10 first accesses the back end 20, and the allocation and management of authority may refer to the relevant technology.

[0043] The first client 30 and the second client 40 can be personal computers, laptops, etc. The first client 30 and the second client 40 are located in the same local area network. The first client 30 is in a powered-on state or a standby state, and the second client 40 is in a powered-off state. It should be noted that the second client in the same local area network can be multiple devices. The embodiment of the present application does not specifically limit the number of second clients. When the first client in the same local area network is already in a powered-on or standby state, the states of multiple second clients can all be powered-off.

[0044] like Figure 2 As shown, when a network wake-up mirror switching operation is performed, the first client 30 is used to receive a wake-up instruction, which includes information about the mirror to be switched, and then organizes the wake-up instruction and the information about the mirror to be switched into a wake-up packet, and finally sends the wake-up packet to the second client 40, so that the second client 40 is activated according to the wake-up packet and enters the power-on state.

[0045] In some embodiments, multiple first clients 30 and at least one second client 40 are included, and the back end 20 sends a wake-up instruction to the multiple first clients 30 in the local area network, and the multiple first clients 30 receive the wake-up instruction respectively, wherein each first client 30 generates a wake-up packet according to the received wake-up instruction. After obtaining the wake-up packet, the grouping information of the second client 40 is obtained according to the number of the second clients 40, and the grouping information is generated when the second client 40 initializes access to the network wake-up mirror switching system. According to the grouping information, the multiple first clients 30 respectively send a wake-up packet to the second client 40 in the group corresponding to each first client 30, so that the second client 40 in the group can be activated according to the received wake-up packet and enter the power-on state.

[0046] Optionally, the first client 30 and the second client 40 can be switched according to whether they have been powered on. After the second client 40 has been powered on successfully, it can become a new first client 30, and then perform corresponding network wake-up mirror switching management on other unpowered devices in the local area network. Similarly, after the second client 40 has been powered on successfully, if the first client 30 is turned off, the first client 30 can become a new second client 40 that can be used for network wake-up mirroring.

[0047] In other embodiments, the process of organizing the wake-up instruction and the information of the image to be switched into a wake-up packet includes: first, determining the structure and fields of the wake-up packet, and according to the determined structure and fields, using the wake-up instruction as part of the wake-up packet to indicate the operation to be performed. Then, the information of the image to be switched is added to the wake-up packet, and the information of the image to be switched includes an identifier, a version number, etc. The identifier and the version number are obtained through the above-mentioned client information interface and are used to represent the image. Finally, a check code can also be added to the wake-up packet, and the check code is used to verify the integrity of the wake-up packet. If the second client 40 verifies the received wake-up packet using the check code after receiving the wake-up packet, and obtains a verification result that the received wake-up packet is incomplete, then the received wake-up packet has security risks such as being tampered with, and the second client 40 discards the wake-up packet and does not execute the wake-up instruction at that time.

[0048] like Figure 2 As shown, when a network wake-up mirror switching operation is performed, the second client 40 is used to receive the wake-up packet, and then parse the wake-up packet to obtain the information of the mirror to be switched and the wake-up operation instruction, and finally the second client 40 enters the power-on state according to the wake-up operation instruction and the information of the mirror to be switched. After the power-on process of the second client 40 is completed, the second client 40 has switched to the mirror to be switched.

[0049] In some embodiments, the process of parsing the wake-up packet to obtain the information of the image to be switched and the wake-up operation instruction includes: first, sending the wake-up packet to the basic input and output system (BIOS) of the second client 40. The basic input and output system is a basic software located between the computer hardware and the operating system. It exists on the motherboard of the computer and is responsible for initializing the system hardware, performing self-test, and providing basic input and output functions to actively start the operating system. Then, the wake-up packet is parsed by the basic input and output system of the second client 40 to obtain the information of the image to be switched and the wake-up operation instruction, and the wake-up operation instruction is stored in the programmable read-only memory (PROM) of the second client 40. After the above-mentioned storage process is completed, the power management chip (Power Management IC, PMIC) of the second client 40 is used to start the power-on operation. The power management chip is used to manage and control the power supply and power management functions of the device. By sending a power-on signal to the main processor, the main processor is notified to start the device. The power-on signal can be a specific level or pulse to wake up or activate the processor. When the main processor receives the power-on signal from the power management chip, it starts the startup process, reads the wake-up operation instruction from the programmable read-only memory, executes the wake-up operation instruction, and switches to the image to be switched according to the information of the image to be switched. When the image to be switched is started, the second client 40 also completes the network wake-up image switching process, and returns the wake-up result of the successful network wake-up image switching to the background 20, and finally, the background 20 returns the wake-up result to the front end 10.

[0050] In some embodiments, for multiple client devices in a local area network, one of the devices in the power-on or standby state is selected as the first client 30, and the other devices in the power-off state are selected as the second client 40. The first client 30 is used to receive the wake-up instruction, and the wake-up instruction includes the information of the image to be switched; the wake-up instruction and the information of the image to be switched are organized into a wake-up packet. The first client 30 sends the wake-up packet to each other second client 40. The information of the image to be switched in the wake-up packet includes different types of images to be switched (such as Windows operating system, Linux operating system, etc.). According to the needs, multiple second clients 40 can obtain their corresponding images to be switched from the wake-up packet respectively, so that the second client 40 switches to the corresponding image to be switched and enters the power-on state. For example, one device needs to run the Windows operating system, and the other device needs to run the Linux operating system. The information of the image to be switched in the wake-up packet can include images of different operating systems, and the second client 40 extracts the corresponding operating system image according to its own identification.

[0051] The embodiment of the present application allows the first client 30 to act as a wake-up server, responsible for receiving wake-up instructions and organizing wake-up packets, while the other second clients 40 in the shutdown state can select the corresponding mirror to switch according to the information of the mirror to be switched in the wake-up packet. The beneficial effects brought by this design include: by organizing the wake-up instructions and the information of the mirror to be switched into a wake-up packet, different types of mirrors to be switched can be flexibly selected, which allows each second client device to select a suitable mirror to switch according to its own needs, providing greater flexibility and customization. The first client acts as a wake-up server, centrally managing the information of the wake-up instructions and the mirror to be switched, which can be more convenient to manage and control. The wake-up packet can be sent by the first client to control the mirror switching of multiple second client devices at one time, simplifying the management process. It can support mirror switching between multiple second client devices in a local area network, so it has good scalability, and more second client devices can be added as needed, and mirror switching can be performed according to the information in the wake-up packet to meet the needs of different devices.

[0052] The embodiment of the present application provides a network wake-up mirror switching system, which generates a switch mirror instruction at the front end and sends the switch mirror instruction to the back end, the back end generates a wake-up instruction according to the switch mirror instruction, and sends the wake-up instruction to the first client, the first client generates a wake-up packet containing information of the image to be switched according to the wake-up instruction, and then sends the wake-up packet to the second client, the second client parses the wake-up packet to obtain the information of the image to be switched and the wake-up operation instruction, and then the second client enters the boot state, executes the wake-up operation instruction, and switches to the image to be switched according to the information of the image to be switched, wherein the first client and the second client are in the same local area network. The network wake-up mirror switching system of the present application not only realizes the remote wake-up of the target device to start up and enter the system image, but also enables the target device to start up and enter the target system image according to the wake-up packet, thereby improving the user's flexibility in selecting and operating the system image on the target computer device. In addition, by generating the switch mirror instruction by the front end and sending it to the back end, the back end then sends the wake-up instruction to the first client, the first client generates the wake-up packet and sends it to the second client, this multi-level transmission method can reduce the risk of directly sending the wake-up instruction to the second client, because the wake-up instruction is transmitted through multiple layers, and the blocking effect of malicious attacks is better, thereby helping to improve the security of remote wake-up. Furthermore, after receiving the wake-up packet, the second client parses and obtains the information of the image to be switched and the wake-up operation instruction, the second client enters the boot state, and executes the corresponding wake-up operation instruction according to the information of the image to be switched, and switches to the image to be switched, thereby ensuring the accuracy and completeness of switching to the specified image and improving the success rate of remotely waking up the target device. Finally, since the first client and the second client are in the same local area network, the wake-up packet can be sent from the first client to the second client faster, thereby reducing the wake-up time and improving the response speed, and the local area network is usually subject to better security protection measures, and the network wake-up packet is less likely to be intercepted or tampered by unauthorized visitors when transmitted in the local area network.

[0053] See also Figure 3 , Figure 3 1 is a flow chart of a network wake-up mirror switching method provided by an embodiment of the present application, which can be applied to the first client 30. Figure 3 As shown, the method comprises the following steps:
