[0002] The same independent network hardware on an Android device usually uses the same network protocol stack to interact with external network devices, and basically each independent network processes its own related data content. Therefore, this method has shortcomings in terms of complex on-site environments and data security requirements. For example, multiple networks on the market are usually connected to the same switch, and then multiple network data are communicated. At this time, each network on the Android device will receive a large amount of data. Since several networks parse and process data on the same network protocol, data processing will be congested, and there is a possibility of data loss. In addition, due to the complex on-site environment, if a single network device fails, the network will not be able to communicate with the outside world, and there may be situations where data is interrupted, resulting in related controls not being processed in time.

[0003] Therefore, how to improve the reliability of network communication is a problem that needs to be solved urgently. Summary of the invention

[0014] If the data reception situation of the first subnet is abnormal and the data reception situation of the second subnet is normal, the second subnet is selected as the communication subnet.

[0043] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0044] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0045] The main solution of the present application is: inputting external network data into the protocol stack processing module of the network driver transmission layer through the sub-network, and parsing and processing the external network data through the protocol stack processing module to obtain parsed data, and the sub-network corresponds to the protocol stack processing module one by one; returning the parsed data to the socket of the preset application layer, communicating with the external network through the sub-network, and the preset application layer reading and writing data through the socket.

[0046] In the market, multiple networks are usually connected to the same switch, and then multiple network data are communicated. At this time, each network on the Android device will receive a large amount of data. Since several networks parse and process data on the same network protocol, data processing will be congested, resulting in the possibility of data loss. In addition, due to the complex on-site environment, if a single network device fails, the network will be unable to communicate with the outside world, and there will be data interruptions, resulting in related controls not being processed in time.

[0047] Therefore, how to improve the reliability of network communication is a problem that needs to be solved urgently.

[0048] The present application establishes multiple protocol stack processing modules so that different sub-networks can perform data communication in different protocol stack processing modules, thereby overcoming the technical defects of using the same protocol stack processing module in complex field environments and insufficient data security requirements, and improving the reliability of the network communication method.

[0049] It should be noted that the execution subject of this embodiment may be a communication system, or a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a network communication device capable of realizing the above functions, etc., and this embodiment does not specifically limit this. The following takes the communication system as the execution subject as an example to illustrate this embodiment and the following embodiments.

[0050] Based on this, the present application proposes a network communication method of the first embodiment, please refer to Figure 1 The network communication method is executed by a communication system, the communication system includes at least two sub-networks and a network driver transmission layer, the network driver transmission layer includes at least two protocol stack processing modules, and the network communication method includes steps S10 to S20:

[0051] It should be noted that the network driver transport layer refers to the part of the communication system that is responsible for the interaction between the data link layer and the transport layer, and the protocol stack processing module is used to independently process the data of the corresponding sub-network.

[0052] Step S10, inputting the external network data into the protocol stack processing module of the network driver transmission layer through the sub-network, and parsing the external network data through the protocol stack processing module to obtain parsed data, wherein the sub-network corresponds to the protocol stack processing module one by one;

[0053] It should be noted that subnetworks refer to network entities used for data transmission and reception in a communication system, and they correspond one-to-one to protocol stack processing modules. External network data refers to data received from sources outside the communication system. These data may come from the Internet, a local area network, a wide area network, or any other type of network. Parsed data refers to data processed by a protocol stack processing module.

[0054] It can be understood that the network driver transport layer is mainly responsible for providing data transmission services on an end-to-end basis, ensuring that data can be transmitted reliably or unreliably between two terminal devices in the network. The external network sends data to the sub-network for processing through the network driver transport layer, and then sends it to the upper layers such as the application layer and presentation layer.

[0055] In a feasible embodiment, external network data enters the network processing protocol stack (protocol stack processing module) through the network driver transport layer, and is bound to the corresponding network processing protocol stack through the network device (sub-network) to perform UDP (User Datagram Protocol) / TCP (Transmission Control Protocol) data reception and transmission processing. The processed data is returned to the upper application network (preset application layer) socket handle, and the upper layer can now perform data transceiver interface recv (receive) and send (send) operations through the socket handle.

[0056] Furthermore, if Figure 2 and Figure 3 As shown, Figure 2 To illustrate the data processing situation of the communication method of this embodiment, Figure 3 The data processing of the traditional single network protocol stack network communication method is as follows:

[0057] Among them, Tcp and udp represent data types, Recv-Q is the amount of received data, Send-Q is the amount of sent data, Local Address is the local address, Foreign Address is the external address, and State is the status column showing the sending status.

[0058] pass Figure 3 It can be seen from the comparison that when multiple networks share a single network protocol stack, the protocol stack often has data that is not emptied. For example, 2056, 22684, etc. are all cases where the data on the corresponding network is not processed in time. Figure 2 It can be seen that the data retained in the communication method of this embodiment is basically 0, that is, all data has been processed in time.

[0059] In a feasible embodiment, step S10 further includes step S101:

[0060] Step S101, binding the sub-network to the protocol stack processing module, and setting a buffer of the sub-network.

[0061] It should be noted that the buffer refers to the data buffer before the sub-network receives and processes the data and sends it to the socket of the preset application layer, that is, buffer.

[0062] It is understandable that each sub-network is generated by a network device and bound to a protocol stack processing module to establish a one-to-one correspondence between the sub-network and the protocol stack processing module, thereby achieving separate processing of data in each sub-network.

[0063] In a feasible embodiment, first, the corresponding sub-network is bound through the java.net.Socket under the Android system. Then, the buffer size of the sub-network UDP / TCP socket is set in the bound sub-network. The buffer is an indispensable part of data transmission and processing. Correct use and management of the buffer is crucial to ensure system performance and security. Finally, the sizes of the respective send and receive buffers are further set through the Android system mSocket.setSendBufferSize\mSocket.ReceiveBufferSize.

[0064] This embodiment implements the binding of the sub-network with the protocol stack processing module through the java.net.Socket under the Android system, which can ensure that the network communication of the application program is targeted at a specific network interface, thereby improving the stability and performance of the connection, especially in a multi-network environment.

[0065] Step S20, returning the parsed data to the socket of the preset application layer, communicating with the external network through the sub-network, and the preset application layer reading and writing data through the socket.

[0066] It should be noted that the default application layer refers to the layer responsible for providing services or functions directly to users in network communication. The default application layer is the highest layer in the network layered model. A socket is a communication endpoint that allows a program to send data to or receive data from the network.

[0067] It can be understood that data communication at the application layer is achieved through sockets, and data communication with the external network is achieved through the sub-network bound to the network device, thereby achieving communication between the user and the external network among multiple network devices.

[0068] The communication method of this embodiment realizes network communication by establishing multiple protocol stack processing modules to individually process the data of each sub-network, thereby solving the problem of network data loss caused by untimely network protocol stack processing during network large data flow communication, and thus improving the reliability of network communication.

[0069] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and no further description will be given later. Figure 4 , the network communication method further includes:

[0070] Step S01, forming a redundant network with two of the subnets as a group, and communicating with an external network through the redundant network, wherein the redundant network includes a first subnet and a second subnet, and the first subnet is a subnet for communicating with an external network in a default setting;

[0071] It should be noted that a redundant network refers to a network that communicates by configuring two subnets. The first subnet refers to the main network in the redundant network that communicates with the external network by default, that is, in general, the first subnet is responsible for receiving and sending external network data, while the second subnet does not send data to the external network, but receives external network data from the external network.

[0072] like Figure 5 As shown, Figure 5 The figure is a schematic diagram of the principle of redundant network communicating with external network, where LAN1, LAN2, LAN3 and LANn refer to sub-networks. The sub-networks communicate with external network through switches, and sub-networks form redundant network in groups of two. Generally, the sub-network with the earlier serial number is the first sub-network by default. For example, in the redundant network of LAN1 and LAN2, LAN1 is the first sub-network by default, and LAN2 is the second sub-network.

[0073] It is understandable that there may be more than four sub-networks. When the number of sub-networks exceeds four, if two-by-two sub-networks are used to form a redundant network, it is still regarded as using the network communication method of this embodiment.

[0074] In another feasible embodiment, the redundant network is formed by more than two sub-networks, which can further improve the reliability of network communication.

[0075] In a feasible embodiment, the two sub-networks in step S01 are grouped together, and the step of forming a redundant network further includes step S011:

[0076] Step S011: The first subnet and the second subnet are combined into the redundant network through network multicast.

[0077] It can be understood that network multicast is an efficient network communication technology that allows a data packet to be sent from a source host to a specific group of recipients rather than a single destination or all devices in the network. This method can significantly save bandwidth and reduce network congestion when transmitting data to multiple recipients compared to unicast and broadcast. In this embodiment, the external network is equivalent to the source host and the subnet is equivalent to the recipient.

[0078] This embodiment uses network multicast, which can significantly save bandwidth and reduce network congestion compared to unicast and broadcast, thereby improving data transmission efficiency, reducing network load, and can transmit across network segments, only transmitting data streams to places where there are receivers, thereby avoiding traffic redundancy.

[0079] Step S02, selecting a communication subnet from the first subnet and the second subnet according to the data reception conditions of the first subnet and the second subnet, wherein the communication subnet is a subnet for communicating with the external network;

[0080] It is understandable that, under normal circumstances, the first subnet is a communication subnet, and when a communication error occurs in the first subnet, the second subnet needs to be selected as the communication subnet.

[0081] In a feasible embodiment, the step S02 of selecting a communication subnet from the first subnet and the second subnet according to the data reception conditions of the first subnet and the second subnet further includes steps A10 to A20:

[0082] Step A10, if the data reception of the first subnet is normal, selecting the first subnet as the communication subnet;

[0083] It is understandable that the normal data reception means that the first subnet can receive the external network data sent by the external network. Regardless of whether the second subnet can normally receive the external network data, the first subnet is selected as the communication subnet by default.

[0084] Step A20: If the data reception situation of the first subnet is abnormal and the data reception situation of the second subnet is normal, the second subnet is selected as the communication subnet.

[0085] It is understandable that when the first subnet cannot receive external network data, the second subnet needs to be detected. If the second subnet can normally receive external network data, the second subnet is used as a communication subnet.

[0086] This embodiment selects a communication network based on data reception conditions, thereby avoiding abnormalities in network communication of the entire communication system caused by abnormal data reception in the first subnet in the redundant network, thereby improving the reliability of the network communication method of this embodiment.

[0087] Step S03: adjusting the selection of the communication subnet according to the connection status of the communication subnet.

[0088] It is understandable that during network communication, the network connection may be temporarily disconnected, and the communication subnet cannot be replaced in time by selecting the communication subnet based on the data reception situation.

[0089] In a feasible embodiment, by constructing a process to monitor the link status (connection status) of the subnet, and by monitoring the link status in real time, after selecting the communication subnet based on the data reception situation, the communication subnet is further selected. Through this embodiment, after a communication failure occurs in the communication subnet, the communication subnet can be replaced more quickly than when the communication subnet is selected only based on the data reception situation, thereby improving the reliability and security of network communication.

[0090] In another feasible embodiment, after selecting a communication subnet according to the link status, a communication subnet is further selected according to the situation of receiving external network data by the communication subnet. The reliability of network communication can be improved by the method of this embodiment.

[0091] In another feasible embodiment, the communication subnet is selected by the data reception situation while the link status of the subnet is monitored to adjust the communication subnet. This embodiment improves the rate of network communication by comprehensively selecting the communication subnets at the same time.

[0092] In a feasible embodiment, the redundant network includes the communication subnet and the redundant subnet, the communication subnet and the redundant subnet both receive external network data, the communication subnet can send data to the external network, and step S03 also includes steps B10 to B30:

[0093] It should be noted that, generally, that is, when the first subnet can communicate with the external network normally, the first subnet is a communication subnet and the second subnet is a redundant subnet.

[0094] Step B10, if the connection status of the communication subnet is normal, communicate with the external network through the communication subnet;

[0095] It is understandable that if there is no abnormality in the connection status of the communication subnet, there is no need to replace the communication subnet, and communication with the outside is performed through the original communication subnet.

[0096] Step B20, if the connection status of the communication subnet is abnormal, and the connection status of the redundant subnet is normal, communicate with the external network through the redundant network;

[0097] It is understandable that when the connection status of the communication subnet is abnormal, it is necessary to determine whether the connection status of the redundant subnet is abnormal. When the connection status of the redundant subnet is normal, communication with the external network is performed through the redundant subnet, and the redundant subnet is equivalent to a communication network.

[0098] Step B30: If the connection status between the communication subnet and the redundant subnet is abnormal, an alarm signal is issued.

[0099] When the connection status of the communication subnet and the redundant subnet are both abnormal, an alarm signal is issued to alert the user of the abnormality and remind the user that the network communication is abnormal.

[0100] This embodiment selects a communication subnet according to the connection status, which can improve the reliability, stability and security of the communication system, and can ensure the continuous operation of network communications and continuous transmission of data even when network conditions are not ideal or a failure occurs.

[0101] For example, to help understand the technical concept or technical principle of the network communication method after combining this embodiment with the above-mentioned embodiment 1 and embodiment 2, please refer to Figure 6 , Figure 6 A brief flow chart of a network communication method is provided, as follows:

[0102] External network data enters the network processing protocol stack (pre-opened memory space) through the network driver transport layer, and is bound to the corresponding network protocol stack processing space (protocol stack processing module) through the corresponding network device to perform UDP / TCP data reception and transmission processing. The processed data is returned to the upper application network (application layer) socket handle (socket), and the upper layer can now perform data reception and transmission interface recv and send operations through the socket handle.

[0103] Before performing network read and write operations on the upper-layer socket, the redundancy judgment arbitration unit is entered, and the arbitration unit performs relevant logical judgments and selects which network is used as the main network to communicate with the external network device, that is, selects the communication subnet to communicate with the external network device.

[0104] Among them, LAN1, LAN2, LAN3 and LANn refer to sub-networks, each of which is generated by a network device and bound to a protocol stack processing module through the network device.

[0105] For further information, please refer to Figure 7 , Figure 7 A flowchart of the protocol stack processing module binding and redundancy mechanism is provided, specifically:

[0106] Protocol stack processing module binding process:

[0107] The first step is to initialize the network driver, start the network communication system, and perform necessary configuration.

[0108] The second step is to configure the network protocol stack to adapt to different network environments and requirements.

[0109] The third step is to use network-related interfaces: use interfaces such as java.net.Socket for network communication.

[0110] The fourth step is to set the size of each independent protocol stack: set the buffer size for each protocol stack, and configure the receive and send buffer of each network through the mSocket.setSendBufferSize and mSocket.setReceiveBufferSize methods.

[0111] Redundancy mechanism process:

[0112] The first step is network communication initialization: complete the initialization of network communication.

[0113] The second step is to determine the network link status: check the network connection status and determine whether both networks are in an abnormal state.

[0114] In the third step, if the network link status is abnormal, the link status of the two sub-networks in the redundant network is monitored. If the link status monitoring of the two sub-networks is abnormal, an abnormal alarm is issued. If there is a normal sub-network, the normal sub-network is selected as the communication sub-network for network sending and receiving communications.

[0115] Step 4: If the network link status is normal, enter the transceiver interface: set the network's receiving and sending interfaces.

[0116] Step 5. Select the sending network through the network receiving data: When LAN1 and LAN2 are both normal, LAN1 is selected by default for data sending.

[0117] Step 6: External network multicast communication: Communicate with external nodes through multicast, and use specific port numbers to distinguish different communication nodes.

[0118] Among them, the network refers to the redundant network, and LAN refers to the subnetwork.

[0119] It can be understood that the network communication method of the present application is aimed at the network communication under the Android system through this multi-protocol stack redundancy mechanism, which greatly improves the loss of network data caused by the untimely processing of the network protocol stack during the network large data flow communication. At the same time, the network redundancy mechanism brings a reliable and secure communication mechanism to the communication control system of the entire network. Combined with the current communication control is mainly transmitted through the network, the present invention has good security and reliable communication advantages in complex network environments.

[0120] The present application also provides a network communication device. Figure 8 , the network communication device comprises:

[0121] The data processing module 10 inputs the external network data into the protocol stack processing module of the network driver transmission layer through the sub-network, and parses and processes the external network data through the protocol stack processing module to obtain parsed data, and the sub-network corresponds to the protocol stack processing module one by one;

[0122] The communication module 20 returns the parsed data to the socket of the preset application layer, communicates with the external network through the sub-network, and the preset application layer reads and writes data through the socket.

[0125] Selecting a communication subnet from the first subnet and the second subnet according to the data reception conditions of the first subnet and the second subnet, wherein the communication subnet is a subnet for communicating with the external network;

[0126] The selection of the communication subnet is adjusted according to the connection status of the communication subnet.

[0127] Optionally, the communication module 20 is further used for:

[0128] If the data reception of the first subnet is normal, selecting the first subnet as the communication subnet;

[0130] Optionally, the redundant network includes the communication subnet and the redundant subnet, both of which receive external network data, and the communication subnet can send data to the external network, and the communication module 20 is further used for:

[0132] If the connection status of the communication subnet is abnormal, and the connection status of the redundant subnet is normal, communicating with the external network through the redundant network;

[0133] If the connection status between the communication subnet and the redundant subnet is abnormal, an alarm signal is issued.
