[0029] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0030] Embodiment 1

[0031] The solution provided in the embodiments of the present application can be applied to any system with network communication capabilities, such as a server system including a chip with network communication functions and related components, etc. Figure 1 A schematic diagram of an application scenario of the network communication solution provided in an embodiment of the present application, Figure 1 The scenario shown is only one of the examples to which the technical solution of the present application can be applied.

[0032] Nowadays, as users are increasingly using the Internet to work, companies can have multiple office spaces in multiple locations, and networks can be provided in each office space so that multiple terminals in the office space can access the Internet. Therefore, users can connect to remote devices that are not with them through the Internet to control the devices. Such remote control technology eliminates the obstacles of region and distance for users to use or control devices, greatly facilitating users' work and life. However, such remote control usually requires that the terminal device that the user uses to access the Internet and the remote device to be controlled are in the same network, which increases the difficulty of remote control for users.

[0033] It has been proposed in the prior art to set a page terminal server in the network where the target device that the user wants to control is located, that is, to additionally set up a page terminal server in the network of the target device that the user wants to control to provide page terminal services to the user, or to install the page terminal service on an existing device in the target device network, so that the device deployed with the page terminal service can allow the user to enter control instructions for the target device on the page of the web page by accessing the web page provided by the server. Since the page terminal server is in the same network as the target device, the page terminal server can connect to the target device and forward the control instructions entered by the user on its page to the target device. Therefore, the user can still connect to the target device and enter control instructions to the target device even if he uses a terminal that is not in the same network as the target device.

[0034] In particular, in the prior art, the target device is often connected to through the communication protocol of Secure Shell (SSH) or Telnet, and these two communication protocols usually require that the terminal where the user logs in is in the same network as the target device. Therefore, in the prior art, a web terminal server is deployed in the network of the target device to provide a web page login service to users in another network, so that the user can access the web page provided by the page terminal server to log in to the target device in the same network as the page terminal server. Therefore, the user logs in to the remote management page provided by the page terminal server on his own terminal to connect to the target device, so that various commands can be input to the target device on the page to control the target device.

[0035] For example, currently most local terminals form a local area network in their location, such as an office, and each terminal is connected to the Internet through a switch device connected to the local area network. However, such a switch device is usually set up in a computer room, and network personnel usually log in to the switch through the local area network using their own terminals to perform operations such as network configuration or daily maintenance on the switch device. However, when network maintenance personnel need to maintain and configure networks in different locations, such as branches in different regions, they need to remotely log in to the switches of these local area networks to perform corresponding operations. For this reason, it is usually necessary to deploy page terminal services in these networks. For example, if the switching device itself supports it, the page terminal service can be installed on the switching device itself, or if the switching device itself does not support it or for security reasons, the page terminal service needs to be installed on other devices, then an additional page terminal server can be set up in the network managed by the switching device to provide such page terminal services. Therefore, network maintenance personnel can directly log in to the switching device by accessing the page provided by the page terminal service, or first log in to the page terminal server in the network where the switching device is located, and then connect to the switching device through the server, thereby using various remote service protocols such as SSH or TELNET to send various control instructions to the switching device.

[0036] However, the solution in the prior art requires that a page terminal server with a page service be deployed in the same network as the target device. For example, in the case where the above-mentioned user wants to remotely control the switching device of the office LAN, it is necessary to deploy a server that can provide page terminal services to the outside in the LAN in advance, or it is necessary to deploy the page terminal service on the switching device. However, under normal circumstances, since the switching device is the only device used to manage the entire office LAN, it is usually not allowed to install such auxiliary tools on the switching device for security reasons. In addition, as the dependence of enterprises on the Internet increases, an enterprise may have multiple office LANs, and therefore if a page terminal server is set up in each network, it will inevitably greatly increase the overhead of the enterprise network.

[0037] For example, Figure 1 As shown in Figure 1 Schematic diagram showing an application scenario of a network communication method according to an embodiment of the present application. Figure 1 In the scenario shown in , when a user wants to use his own terminal to control a target device 1 in a target network different from his own network, in the prior art, the terminal used by the user and the target device are not in the same network. For example, the target device is in a local area network 1, in which there may be multiple devices including the target device, and these devices may be connected to a public network through a switching device such as a switch. Therefore, in the prior art, when the user is not in the target network, it is impossible to establish a communication connection with the target device in the local area network 1. Therefore, in the prior art, it is usually necessary to set up a page terminal server in the local area network 1 so that a user using a terminal in another network can also enter the local area network 1 by accessing the page served by the page terminal, so that the user can send control instructions to the target device in the local area network 1 through the page.

[0038] However, as mentioned above, when there are multiple target devices in different local area networks, setting up a page terminal server in each network will greatly increase the user's expenses. Figure 1 The control devices in the local area networks 1 and 2 shown in the figure establish communication channels respectively, so that a user can establish a communication connection with a target device in the target network through the communication channel established between the cloud server and the target network by accessing the cloud server.

[0039] For example, in an embodiment of the present application, a branch controller may be deployed in each target network to control data communication between devices in the target network and an external network. For example, the branch controller may be used to control a switch device in the target network, so that each target device connected to the switch device can communicate with the cloud network where the branch manager is located and / or devices in other target networks controlled by other branch controllers. The cloud server may be a branch manager corresponding to each branch controller, which is used to manage each branch controller. In particular, the branch manager may establish a dedicated channel with each branch controller, such as an IPsec tunnel, to provide secure communication between the branch manager and the branch controller, and a terminal service may be deployed in the branch manager. Therefore, in a case such as Figure 1 In the scenario shown in , the user can use his own terminal device to send a control request to the cloud branch manager to control the target device. The control request may include information such as the device identification of the target device. The branch manager determines the network identification of the target device, such as local area network 1, based on the device identification included in the request, and can establish a connection channel with the local area network 1, so that the control instructions for controlling the target device sent by the user through his own terminal to the branch manager can enter the local area network 1 with the help of the connection channel, and therefore, due to the channel established with the help of the branch manager, it can be in the same network as the target device, so that a communication connection can be established with the target device.

[0040] Specifically, the branch manager and the branch controllers it manages are usually connected by means of a VPN (virtual private network) based on the Internet. Therefore, in the embodiment of the present application, by Figure 1The page terminal service is deployed in the branch management server shown in the figure, so that the user terminal can log in to the branch management server and issue a communication request for communicating with the target device 1 in the target network 1 where the branch controller 1 is located. At this time, the above-mentioned connection characteristics between the branch management server and the branch controller it manages can determine the corresponding branch controller 1 according to the target network where the target device is located, and thus can directly establish a communication channel with the branch controller 1, such as an IPsec (Internet Security Protocol) VPN encrypted tunnel, and the branch controller 1 as a controller managing the target network can directly establish a connection with the target device in the network, so that for the user terminal, the communication data sent to the branch management server can be sent to the branch controller 1 by means of the communication channel between the branch management server and the corresponding branch controller in the target network, and the branch controller 1 can send the communication device of the user terminal to the target device through the connection with the target device after receiving the communication data. Therefore, for the user terminal, it only needs to log in to the cloud server on the public network, and can send its own communication data to the target device to be controlled or managed by means of the exclusive communication channel between the server and the target network. Compared with the solution in the prior art that requires setting up a page terminal server for user access in each target network, the embodiment of the present application only needs to deploy the service in the cloud server for the user terminal to log in, so that the user can achieve communication connection with the target device in each target network. This greatly reduces the cost of achieving communication between the user terminal and the target device in each target network.

[0041] The network communication solution provided by the embodiment of the present application receives a communication request from a user terminal to communicate with a target device, and determines the target network according to the device identifier in the communication request, thereby establishing a communication channel with the target network to send the communication data of the user terminal to the target device through the communication channel. Therefore, by establishing a communication channel with the target network where the target device is located, the communication device of the user terminal can be sent to the target device through the communication channel, thereby realizing remote control of target devices in different networks, so that a channel can be established with the target network through a cloud server that can receive the communication request of the user terminal, so that the user's communication data can be sent to the target device in the target network through the channel between the cloud server and the target network, eliminating the need for additional configuration of a server in the target network to receive the communication request of the user terminal, thereby greatly reducing the cost of realizing network communication from the user terminal to the target device.

[0042] The above embodiments are illustrations of the technical principles and exemplary application frameworks of the embodiments of the present application. The specific technical solutions of the embodiments of the present application are further described in detail below through multiple embodiments.

[0043] Embodiment 2

[0044] Figure 2 This is a flowchart of an embodiment of the network communication method provided by the present application. The execution subject of the method can be various terminals or server devices with network communication capabilities, or it can be a device or chip integrated on these devices. Figure 2 As shown, the network communication method includes the following steps:

[0045] S201, receiving a communication request sent by a user terminal to communicate with a target device.

[0046] In step S201, a communication request sent by a user terminal may be received, and the communication request may be an operation instruction for a user to log in to, for example, a cloud server and specify in the cloud server to communicate with a target device. Therefore, the communication request received in step S201 may be a request sent by a user terminal received by a cloud server running on a public network, and may include a device identifier of a target device with which the user terminal wants to establish communication.

[0047] S202: Determine the target network where the target device is located according to the device identifier.

[0048] In step S202, the target network where the target device is located can be determined according to the device identifier of the target device included in the communication request received in step S201. For example, the communication request of the user can be received by a management server in the cloud in step S202, and therefore, since the management server in the cloud is responsible for managing each target network, a list of devices in each target network can exist in the management server, and therefore, in step S202, the device identifier in the communication request received in step S201 can be searched in such a list, and the target network to be connected can be determined according to the corresponding relationship between the device and the network.

[0049] S203, establishing a communication channel with the target network.

[0050] In step S203, a communication channel may be established with the target network according to the target network determined in step S202. In the embodiment of the present application, the communication channel may be a VPN encrypted tunnel or an Internet Security Protocol channel.

[0051] S204, sending the communication data sent by the user terminal to the target device through the communication channel.

[0052] In step S204, the communication data of the user terminal may be sent to the target device in the target network by means of the communication channel with the target network established in step S203.

[0053] The network communication method provided in the embodiment of the present application receives a communication request from a user terminal to communicate with a target device, and determines the target network according to the device identifier in the communication request, thereby establishing a communication channel with the target network to send the communication data of the user terminal to the target device through the communication channel. Therefore, by establishing a communication channel with the target network where the target device is located, the communication device of the user terminal can be sent to the target device through the communication channel, thereby realizing remote control of target devices in different networks, so that a communication channel for direct communication with the target network can be established through a cloud server that can receive the communication request of the user terminal, so that the user's communication data can be sent to the target device in the target network through the channel between the cloud server and the target network, eliminating the need for additional configuration of a server in the target network to receive the communication request of the user terminal, thereby greatly reducing the cost of realizing network communication from the user terminal to the target device.

[0054] Embodiment 3

[0055] Figure 3 This is a flowchart of another embodiment of the network communication method provided by the present application. The execution subject of the method can be various terminals or server devices that can provide page terminal services to users, or it can be a device or chip integrated on these devices. Figure 3 As shown in the above Figure 2 Based on the illustrated embodiment, the network communication method provided in the embodiment of the present application may include the following steps:

[0056] S301, receiving a communication request sent by a user terminal to communicate with a target device.

[0057] In step S301, a communication request sent by a user terminal may be received. The communication request may be an operation instruction for a user to log in to a branch management server, for example, in the cloud and specify in the branch management server to communicate with the target device. In an embodiment of the present application, the target device may be in each target network different from the cloud network where the branch management server is located, and a branch controller may be deployed in each target network to control data communication between the device in the target network and the external network. For example, the branch controller may be used to control the switch device in the target network, so that each target device connected to the switch device can communicate with the cloud network where the branch manager is located and / or other target networks controlled by other branch controllers. The branch management server in the cloud can manage each branch controller by establishing a channel with these branch controllers, and then manage the target network controlled by each branch controller.

[0058] In particular, a page terminal service, for example, may be deployed in the branch management server in the cloud, and therefore, the user can first log in to the branch management server to use the terminal service by accessing the page provided by the page terminal service of the branch management server in step S201, and therefore, on the page, a communication request can be sent to the branch management server by selecting a target device to communicate with, and therefore, the communication request received in step S301 may include the device identifier of the target device with which the user terminal wants to establish communication.

[0059] S302: Determine the target network where the target device is located according to the device identifier.

[0060] In step S302, the target network where the target device is located can be determined based on the device identifier of the target device included in the communication request received in step S301. For example, in step S301, the branch management server receives a communication request sent by a user by selecting a target device to communicate on a page, so the branch management server in the cloud can search for the device identifier of the target device in each target network it is responsible for managing. Alternatively, the branch management server can also distribute the device identifier to the branch controllers in each target network it manages to instruct the branch controllers to match the device identifier in the branch networks it controls. Therefore, when a matching target device is found, the corresponding target network can be determined as the target network to be connected.

[0061] S303, establishing a communication channel with a branch controller in the target network.

[0062] In step S303, a communication channel can be established with the branch controller in the target network according to the target network determined in step S302. The branch management server and the branch controllers it manages are usually connected by means of a VPN (virtual private network) based on the Internet. Therefore, in step S303, a VPN encryption tunnel or an Internet security protocol channel can be established between the branch management server logged in by the user and the branch controller in the target network determined in step S302. Thus, the branch management server can directly communicate data with the branch controller through the channel.

[0063] S304, instructing the branch controller in the target network to establish a connection with the target device.

[0064] In step S304, after or at the same time as establishing a communication channel with the branch controller in the target network determined in step S302, the branch management server may instruct the branch controller to establish a connection with the target device indicated by the communication request received in step S301. For example, when the target device is a switch device in the target network, in step S304, the branch management server may instruct the branch controller to establish an interactive connection with the switch device to receive the user's communication data.

[0065] S305: Send the communication data sent by the user terminal to the target device through the communication channel.

[0066] In step S305, the communication data of the user terminal can be sent to the target device in the target network by means of the communication channel with the branch controller established in step S303 and the connection between the branch controller and the target device established in step S304. For example, the user logs in to the branch management server through the page terminal service provided by the branch management server in step S301 and selects, for example, Figure 1 As the communication object, the branch management server establishes a communication channel with the branch controller through step S303. Therefore, in step S305, the user can send control commands of communication protocols such as Secure Shell Protocol (SSH) or Remote Login Service (TELNET) directly to the branch controller in the target network through the channel, and the branch controller sends the user's control commands received through the channel to the target device by means of the interactive connection established with the target device such as a switch device in step S304.

[0067] The network communication method provided in the embodiment of the present application receives a communication request from a user terminal to communicate with a target device, and determines the target network according to the device identifier in the communication request, thereby establishing a communication channel with the target network to send the communication data of the user terminal to the target device through the communication channel. Therefore, by establishing a communication channel with the target network where the target device is located, the communication device of the user terminal can be sent to the target device through the communication channel, thereby realizing remote control of target devices in different networks, so that a channel can be established with the target network through a cloud server that can receive the communication request of the user terminal, so that the user's communication data can be sent to the target device in the target network through the channel between the cloud server and the target network, eliminating the need for additional configuration of a server in the target network to receive the communication request of the user terminal, thereby greatly reducing the cost of realizing network communication from the user terminal to the target device.

[0068] Embodiment 4

[0069] Figure 4 The schematic diagram of the structure of the embodiment of the network communication device provided by the present application can be used to perform Figure 2 or Figure 3 The network communication method shown in Figure 4 As shown, the network communication device may include: a receiving module 41 , a determining module 42 , an establishing module 43 and a sending module 44 .

[0070] The receiving module 41 may be configured to receive a communication request sent by a user terminal to communicate with a target device.

[0071] The receiving module 41 may receive a communication request sent by a user terminal, and the communication request may be an operation instruction for a user to log in to, for example, a cloud server and specify in the cloud server to communicate with a target device. Therefore, the communication request received by the receiving module 41 may be a request sent by a user terminal received by a cloud server running on a public network, and may include a device identifier of a target device with which the user terminal wants to establish communication.

[0072] The determination module 42 may be configured to determine the target network where the target device is located according to the device identification.

[0073] The determination module 42 may determine the target network where the target device is located according to the device identifier of the target device included in the communication request received by the receiving module 41. For example, a management server in the cloud may be used as the determination module 42 to receive the user's communication request, and therefore, since the management server in the cloud is responsible for managing each target network, a list of devices in each target network may exist in the management server, and therefore, in step S202, the device identifier in the communication request received by the receiving module 41 may be searched in such a list, and the target network to be connected may be determined according to the correspondence between the device and the network.

[0074] The establishing module 43 may be used to establish a communication channel with the target network.

[0075] The establishing module 43 may establish a communication channel with the target network according to the target network determined by the determining module 42. In the embodiment of the present application, the communication channel may be a VPN encryption tunnel or an Internet security protocol channel.

[0076] For example, the branch management server as the receiving module 41 and the branch controllers it manages can usually be connected by means of a VPN (virtual private network) based on the Internet, so the establishing module 43 can establish a VPN encryption tunnel or an Internet security protocol channel between the branch management server logged in by the user and the branch controller in the target network determined by the determining module 42. Thus, the branch management server can directly communicate data with the branch controller through the channel.

[0077] In addition, after or at the same time as the establishment module 43 establishes the communication channel between the branch management server and the branch controller in the target network determined by the determination module 42, the establishment module 43 may instruct the branch controller to establish a connection with the target device indicated by the communication request received by the receiving module 41. For example, when the target device is a switch device in the target network, the establishment module 43 may instruct the branch controller to establish an interactive connection with the switch device to facilitate receiving the user's communication data.

[0078] The sending module 44 may be configured to send the communication data sent by the user terminal to the target device through the communication channel.

[0079] The sending module 44 can send the communication data of the user terminal to the target device in the target network by means of the communication channel with the target network established by the establishing module 43.

[0080] The network communication device provided in the embodiment of the present application receives a communication request from a user terminal to communicate with a target device, and determines the target network according to the device identifier in the communication request, thereby establishing a communication channel with the target network to send the communication data of the user terminal to the target device through the communication channel. Therefore, a communication channel that can directly communicate with the device can be established with the target network where the target device is located, so that the communication device of the user terminal can send communication data such as instructions to the target device through the communication channel, thereby realizing remote control of target devices in different networks, so that a communication channel for direct communication with the target network can be established through a cloud server that can receive the communication request of the user terminal, so that the user's communication data can be directly sent to the target device in the target network through the channel between the cloud server and the target network, eliminating the need for additional configuration of a server in the target network to receive the communication request of the user terminal, thereby greatly reducing the cost of realizing network communication from the user terminal to the target device.

[0081] Embodiment 5

[0082] Figure 5 This is a schematic diagram of the structure of an embodiment of the network communication system provided by the present application. Figure 2 or Figure 3 The network communication method shown in Figure 5 As shown in , the network communication system may include: a branch management server 51 and at least one branch controller 52. The branch management server 51 may be used to manage at least one branch controller 51 and provide page terminal services to users, and at least one branch controller 51 may be used to control the network where the branch controller is located and there is at least one target device in the network.

[0083] Therefore, the branch management server 51 can be further used to: receive a communication request sent by a user terminal to communicate with a target device; determine the network where the target device is located based on the device identifier; establish a communication channel with the network; and send the communication data sent by the user terminal to the target device through the communication channel.

[0084] Specifically, a page terminal service may be deployed in the branch management server 51. For example, the branch management server 51 may provide a page terminal service to the user by including a page terminal service module. Therefore, the user may log in to the branch management server 51 through the page provided by the branch management server 51, and may select the target device that the user wants to control based on various remote service protocols such as SSH or TELNET on the page to send a communication request to the branch management server 51. Since the devices that the user wants to remotely control are usually located in target networks different from the cloud network where the branch management server is located, and each target network may be respectively deployed with a branch controller for controlling the data communication between the device in the target network and the external network, for example, the branch controller may be used to control the switch device in the target network, so that each target device connected to the switch device can communicate with the cloud network where the branch manager is located and / or other target networks controlled by other branch controllers. The branch management server in the cloud can manage each branch controller by establishing a channel with these branch controllers, and then manage the target network controlled by each branch controller.

[0085] The branch management server 51 and the branch controllers 52 it manages are usually connected by means of an Internet-based VPN (Virtual Private Network). Therefore, under normal circumstances, the branch management server 51 can determine the target network where the target device is located based on the device identifier of the target device contained in the received communication request. For example, the branch management server 51 can search for the device identifier of the target device in each target network it is responsible for managing. Alternatively, the branch management server 51 can also distribute the device identifier to the branch controllers 52 in each target network it manages to instruct the branch controllers 52 to match the device identifier in the branch network it controls. Therefore, when a matching target device is found, the corresponding target network can be determined as the target network to be connected.

[0086] The branch management server 51 can then establish a communication channel with the corresponding branch controller 52 according to the determined target network. For example, the branch management server 51 can establish a VPN encrypted tunnel or an Internet security protocol channel with the branch controller 52 as a terminal service channel for user remote management, or a logical sub-channel can be divided out from the branch management encrypted communication channel that has been established between the branch management server 51 and the branch controller 52 as a terminal service channel for user remote management, so that the user terminal can directly communicate data with the device managed by the branch controller through the channel. The branch management server 51 can instruct the branch controller 52 to establish a connection with the target device indicated by the communication request after or at the same time as establishing a communication channel with the branch controller 52. For example, when the target device is a switch device in the target network, the branch management server 51 can instruct the branch controller 52 to establish an interactive connection with the switch device to facilitate receiving the user's communication data.

[0087] Finally, the branch management server 51 can send the communication data of the user terminal to the target device in the target network by means of the communication channel with the branch controller 52 and the interactive connection between the branch controller 52 and the target device.

[0088] Therefore, in the network communication system of the embodiment of the present application, with the help of the above-mentioned connection characteristics between the branch management server 51 and the branch controller 52 managed by it, the corresponding branch controller 52 can be determined according to the target network where the target device that the user wants to control is located, and therefore the branch management server 51 can directly establish a separate communication channel with the branch controller 52, such as an IPsec (Internet Security Protocol) VPN encrypted tunnel or divide logical sub-channels in the established communication channel as the terminal service channel, and the branch controller 52 as the controller managing the target network can directly establish a connection with the target device in the network, so that for the user terminal, the communication data sent to the branch management server 51 can be sent to the branch controller 52 with the help of the communication channel between the branch management server 51 and the corresponding branch controller 52 in the target network, and after receiving the communication data, the branch controller 52 can send the communication device of the user terminal to the target device through the connection between the target device.

[0089] Therefore, for the user terminal, it only needs to log in to the branch management server 51 on the public network, and can use the exclusive communication channel between the server and the branch controller 52 to send its communication data to the target device that it wants to control or manage. Compared with the solution in the prior art that requires a page terminal server to provide user access in each target network, the embodiment of the present application only needs to deploy the service in the cloud server for the user terminal to log in, and the user can achieve communication connection with the target device in each target network. The cost of realizing communication between the user terminal and the target device in each target network is greatly reduced.

[0090] The network communication system provided by the embodiment of the present application receives a communication request from a user terminal to communicate with a target device through a branch management server capable of providing a page terminal service to the user, and determines the target network according to the device identifier in the communication request, thereby establishing a communication channel with a branch controller in the target network to send the communication data of the user terminal to the target device through the communication channel. Therefore, by establishing a communication channel with a branch controller in the target network where the target device is located, the communication device of the user terminal can be sent to the target device through the communication channel, thereby realizing remote control of target devices in different networks, thereby realizing a channel with the branch controller of the target network through a branch management server capable of receiving the communication request of the user terminal, thereby realizing the communication data of the user can be sent to the target device in the target network through the channel between the branch management server and the branch controller of the target network, thereby eliminating the need for additional configuration of a server in the target network for receiving the communication request of the user terminal, thereby greatly reducing the cost of realizing network communication from the user terminal to the target device.
