Fig. 1 is a flowchart of a network communication method provided by an embodiment of the present invention, where the embodiment of the present invention is applicable to a scenario in which a communication channel is established between a client and the internet of things, the method may be performed by a network communication device, and the device may be implemented by software and/or hardware.
As shown in fig. 1, the network communication method includes the steps of:
and S110, under the condition that a network communication request instruction sent by the client is acquired, determining the Internet of things to be connected according to the network communication request instruction.
The network communication request instruction may be an instruction sent by the client to request communication with the target internet of things. The network communication request instruction may include relevant identification information of the client and identification information of the target internet of things. The to-be-connected internet of things can be the internet of things which needs to be in communication connection with the client, and specifically, under the condition that a network communication request instruction sent by the client is obtained, the to-be-connected internet of things can be determined according to the identification information of the target internet of things in the network communication request instruction.
S120, determining a target network connection mode according to the network association relation between the client and the to-be-connected Internet of things.
The network association relationship may be an association relationship between the client and the internet to be connected in an intranet or a public network. The internal network manager may be a server that manages network connection relationships in a local area network where the client is located. The internet of things search instruction may be an instruction for requesting to search whether the internet of things to be connected exists in the local area network where the client is located. And sending the Internet of things searching instruction to the internal network manager. The internal network manager can search the internal local area network corresponding to the client for the Internet of things to be connected, so that whether a communication channel between the client and the Internet to be connected can be established based on the local area network can be conveniently determined according to the search result. By determining the target network connection mode based on the network association relation between the client and the internet to be connected, a more suitable communication connection mode can be matched according to the network connection relation between the client and the internet to be connected, and the communication connection efficiency is improved.
S130, establishing a target communication connection channel between the client and the to-be-connected Internet of things based on the target network connection mode.
The target communication connection channel may be a communication connection channel established between the client and the internet of things to be connected. Specifically, a corresponding communication connection channel can be established according to the type of the target network connection mode, and the established communication connection channel is used as a target communication connection channel.
Specifically, when a target communication connection channel is established between a client and the internet of things to be connected based on a target network connection mode, the method can be divided into multiple cases. The method comprises the steps of establishing a target local area network communication channel based on a local area network association relation between a client and an internet of things to be connected under the condition that a target network connection mode is a local area network connection mode; under the condition that the target network connection mode is a public network direct connection mode, a target public network direct communication channel is established based on a public gateway connection relation between a client and the to-be-connected Internet of things; and under the condition that the target network connection mode is a public network direct connection mode, establishing a target public network indirect communication channel according to network addresses of the client and the to-be-connected Internet of things in the public network.
The target lan communication channel may be a connection channel established based on the client lan and capable of direct communication. Specifically, under the condition that the target network connection mode is determined to be the local area network connection mode, the client side and the internet to be connected are indicated to be under the same local area network. Therefore, a target local area network communication channel can be established between the client and the to-be-connected internet of things based on the same local area network. The target public network direct communication channel may be a connection channel established based on a public network address and capable of direct communication. Specifically, when the target network connection mode is determined to be the public network direct connection mode, it is indicated that the client and the internet to be connected can directly communicate through the public network address, so that a target public network direct communication channel can be established between the client and the internet to be connected. Further, the target public network indirect communication channel may be an indirect communication connection channel that requires a public network as a communication medium. Specifically, when the target network connection mode is determined to be the public network indirect connection mode, it is indicated that the client and the internet of things to be connected cannot directly communicate through the public network address, so that the public network is required to be used as a communication medium for communication between the client and the internet of things to be connected, and a target public network indirect communication channel is established between the client and the internet of things to be connected.
According to the technical scheme provided by the embodiment of the invention, the Internet of things to be connected is determined according to the network communication request instruction under the condition that the network communication request instruction sent by the client is acquired; determining a target network connection mode according to the network association relation between the client and the to-be-connected Internet of things; and establishing a target communication connection channel between the client and the to-be-connected Internet of things based on the target network connection mode.

Fig. 2 is a flowchart of another network communication method provided by the embodiment of the present invention, where the embodiment of the present invention is applicable to a scenario in which a communication channel is established between a client and an internet of things, and further illustrates how to determine a target network connection mode according to a network association relationship between the client and the internet of things to be connected based on the above embodiment.
As shown in fig. 2, the network communication method includes the steps of:
s210, under the condition that a network communication request instruction sent by a client is obtained, determining the Internet of things to be connected according to the network communication request instruction.
The network communication request instruction may be an instruction sent by the client to request communication with the target internet of things. The network communication request instruction may include relevant identification information of the client and identification information of the target internet of things. The to-be-connected internet of things can be the internet of things which needs to be in communication connection with the client, and specifically, under the condition that a network communication request instruction sent by the client is obtained, the to-be-connected internet of things can be determined according to the identification information of the target internet of things in the network communication request instruction.
S220, determining a target network connection mode according to the network association relation between the client and the to-be-connected Internet of things.
The network association relationship may be an association relationship between the client and the internet to be connected in an intranet or a public network. The internal network manager may be a server that manages network connection relationships in a local area network where the client is located. The internet of things search instruction may be an instruction for requesting to search whether the internet of things to be connected exists in the local area network where the client is located. And sending the Internet of things searching instruction to the internal network manager. The internal network manager can search the internal local area network corresponding to the client for the Internet of things to be connected, so that whether a communication channel between the client and the Internet to be connected can be established based on the local area network can be conveniently determined according to the search result.
S230, the internal network manager searches the internal local area network corresponding to the client for the to-be-connected Internet of things, and determines the target network connection mode according to the Internet of things search result.
The internet of things search result may be a result of searching whether the internet of things to be connected is in an internal local area network corresponding to the client. Specifically, the search results of the internet of things include searched results and searched results. The fact that the internet of things to be connected are not in the internal local area network corresponding to the client is not searched. The searched result indicates that the to-be-connected internet of things is in the internal local area network corresponding to the client. The target network connection mode may be a mode of performing communication connection between the finally determined client and the internet of things to be connected. Specifically, the target network connection mode includes: at least one of a local area network connection mode and a public network connection mode.
The local area network connection mode may be a mode of performing communication connection between the client and the internet to be connected based on an internal local area network corresponding to the client. The public network connection mode can be a mode of carrying out communication connection on the client and the internet of things to be connected based on the public network. Further, the target network connection mode may be determined by the search result of the internet of things, and in an exemplary case where the search result of the internet of things is a searched result, the target network connection mode may be determined to be a local area network connection mode. Correspondingly, under the condition that the search result of the internet of things is not searched, the target network connection mode can be determined to be a public network connection mode.
Further, under the condition that the target network connection mode is determined to be the local area network connection mode, a direct communication channel between the client and the internet of things to be connected can be established based on the local area network, so that the communication rate between the client and the internet is improved. Further, under the condition that the target network connection mode is the public network connection mode, further determination can be made whether a direct communication channel between the client and the Internet of things can be established based on the public network.
Optionally, after determining that the target network connection mode is a public network connection mode, direct communication attempt instructions can be sent to the client and the internet of things to be connected respectively; the method comprises the steps that a client sends client hole punching data to the to-be-connected Internet of things based on a public network, and the to-be-connected Internet of things sends the Internet of things hole punching data to the client based on the public network; and determining a target public network connection mode based on the receiving result of the client and the to-be-connected Internet of things on the hole punching data.
The direct communication attempt instruction may be a request instruction for attempting to directly communicate between the client and the internet of things to be connected. The direct communication attempt instruction can be sent to the client and the internet of things to be connected respectively, so that the direct communication attempt is carried out between the client and the internet of things to be connected based on the public network address, and whether a communication channel between the client and the internet of things to be connected can be established is further determined. Further, the client hole punching data may be hole punching data sent by the client to attempt to directly communicate with the internet of things to be connected. The internet of things hole punching data may be hole punching data to be connected to the internet of things in an attempt to directly communicate with the client.
The target public network connection mode can be a mode of communication connection between the client and the internet to be connected based on the public network. Specifically, the target public network connection mode includes a public network direct connection mode and a public network indirect connection mode. The public network direct connection mode may be a communication connection mode that can directly communicate without a public network. The subsequent client can directly communicate with the to-be-connected internet of things without using a public network as a communication medium. The public network indirect connection mode may be a communication connection mode that can perform communication only through the public network. That is, the client cannot directly communicate with the internet of things to be connected, and a public network is required to be used as a communication medium. For example, when the client and the internet of things send messages to each other, the message sender is required to forward the message to the public network, and then forward the message to the message receiver from the public network.
Specifically, when determining the target public network connection mode based on the receiving result of the client and the internet of things to be connected on the hole punching data, the target public network connection mode can be determined to be the public network direct connection mode when the client receives the internet of things hole punching data and the internet of things to be connected receives the client hole punching data; otherwise, determining that the target public network connection mode is a public network indirect connection mode.
S240, establishing a target communication connection channel between the client and the to-be-connected Internet of things based on the target network connection mode.
The target communication connection channel may be a communication connection channel established between the client and the internet of things to be connected. Specifically, a corresponding communication connection channel can be established according to the type of the target network connection mode, and the established communication connection channel is used as a target communication connection channel.
Specifically, when a target communication connection channel is established between a client and the internet of things to be connected based on a target network connection mode, the method can be divided into multiple cases. The method comprises the steps of establishing a target local area network communication channel based on a local area network association relation between a client and an internet of things to be connected under the condition that a target network connection mode is a local area network connection mode; under the condition that the target network connection mode is a public network direct connection mode, a target public network direct communication channel is established based on a public gateway connection relation between a client and the to-be-connected Internet of things; and under the condition that the target network connection mode is a public network direct connection mode, establishing a target public network indirect communication channel according to network addresses of the client and the to-be-connected Internet of things in the public network.
The target lan communication channel may be a connection channel established based on the client lan and capable of direct communication. Specifically, under the condition that the target network connection mode is determined to be the local area network connection mode, the client side and the internet to be connected are indicated to be under the same local area network. Therefore, a target local area network communication channel can be established between the client and the to-be-connected internet of things based on the same local area network. The target public network direct communication channel may be a connection channel established based on a public network address and capable of direct communication. Specifically, when the target network connection mode is determined to be the public network direct connection mode, it is indicated that the client and the internet to be connected can directly communicate through the public network address, so that a target public network direct communication channel can be established between the client and the internet to be connected. Further, the target public network indirect communication channel may be an indirect communication connection channel that requires a public network as a communication medium. Specifically, when the target network connection mode is determined to be the public network indirect connection mode, it is indicated that the client and the internet of things to be connected cannot directly communicate through the public network address, so that the public network is required to be used as a communication medium for communication between the client and the internet of things to be connected, and a target public network indirect communication channel is established between the client and the internet of things to be connected.
Optionally, before the target communication connection channel is established, preset heartbeat data may also be sent to the candidate gateway device; and acquiring heartbeat feedback information aiming at preset heartbeat data and sent by the candidate gateway equipment, and determining target gateway equipment according to the heartbeat feedback information.
The candidate gateway device may be a gateway device with probability of being a communication connection between the client and the internet of things. The preset heartbeat data may be preset data for checking whether the candidate network device operates normally. By sending the preset heartbeat data to the candidate gateway device, whether the candidate network device operates normally can be determined based on feedback data of the candidate network device to the preset heartbeat data. Further, the heartbeat feedback data may be feedback data of the candidate gateway device to preset heartbeat data. The target gateway device may be a gateway device that is finalized as a communication connection between the client and the internet. Specifically, the heartbeat feedback information may be used to further determine the target gateway device from the candidate gateway devices. For example, whether the heartbeat feedback data and the preset heartbeat data can be successfully matched can be judged, and if the heartbeat feedback data and the preset heartbeat data can be successfully matched, the candidate gateway device sending the heartbeat feedback information can be determined as the target network device. I.e. the gateway device that is operating normally is the gateway device that connects between the client and the internet.

3c) When detecting that the Internet of things gateway to be connected does not exist in the local area network, the client module sends a channel authentication request to the public network server, the authentication success maintains a channel between the Internet through a heartbeat data packet, monitors heartbeat feedback information of the public network server, supports a disconnection reconnection function, inquires the public network server about the on-line state and address information of the designated Internet of things gateway through the communication channel between the client and the public network server, gives up the channel connection if the Internet of things gateway is not on-line, and transfers the Internet of things address between the client and the Internet of things gateway to each other by the public network server if the Internet of things gateway is on-line, and the client and the Internet of things gateway try to send UDP hole-making data packets to each other for a plurality of times, so that the method penetrates NAT equipment of the local area network where each other is located, and the establishment of the direct communication channel crossing the local area network is realized;
3d) When the public network forwarding communication channel is established, and the direct communication channel under the public network environment cannot be successfully established, the communication between the client and the gateway of the Internet of things needs to establish the forwarding communication channel through the channels of the client and the gateway of the Internet of things, the forwarding communication channel is used for sending message data to the public network server firstly, then the public network server analyzes and forwards the message data to a designated destination address through the message processing module, so that the network-based penetrating NAT communication between the client and the gateway of the Internet of things is realized, and the message data can be sent and received mutually.
And 4, the client module exits, after the client module exits, the heartbeat data packet sent to the public network server and the Internet of things gateway module is stopped, the Internet of things gateway and the public network server module both detect the exit of the client, the heartbeat feedback data is stopped to be sent to the client, the online information of the client is not maintained, and the client offline message is detected and displayed.
