[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0028] To address the technical problem of low data transmission efficiency in existing technologies, this application provides a data transmission method that can improve data transmission efficiency.

[0029] Figure 1 This is a flowchart illustrating a data transmission method provided in an embodiment of this application. Figure 1 As shown, the above data transmission method includes:

[0030] S102, In user mode, establish a network connection with each of the multiple terminals and set a socket for each network connection, wherein the socket is used to uniquely identify the network connection;

[0031] S104 records network connections and sockets in kernel mode;

[0032] S106, When the first terminal among multiple terminals transmits target data to the second terminal, the second network connection established with the second terminal is found in the kernel mode through the socket;

[0033] S108, after the target data is transmitted to the kernel state through the first network connection established with the first terminal, the target data is directly transmitted to the second terminal through the second network connection.

[0034] The aforementioned terminals can be terminals running applications, and applications on different terminals can communicate with each other through an intermediary device. For example... Figure 2 In the scenario shown, the intermediate device includes kernel mode and user mode. When the target data is being transmitted, terminal A transmits the target data to the kernel mode of the intermediate device, and the kernel mode directly transmits the target data to terminal B.

[0035] The aforementioned intermediate device can establish a network connection with each participating terminal and assign a socket to each network connection, which uniquely identifies the connection. This network connection and socket can be recorded in kernel mode. When the first terminal transmits target data to the second terminal, the target data first reaches kernel mode through the first network connection between the first terminal and the intermediate device. Then, the second network connection between the intermediate device and the second terminal is located using the socket recorded in kernel mode. The target data is then directly transmitted to the second terminal through this second network connection without waiting for an application layer call.

[0036] The solution provided in this application establishes a network connection between the user space and each of the multiple terminals, and sets a socket for each network connection, wherein the socket is used to uniquely identify the network connection; the network connection and the socket are recorded in the kernel space; when the first terminal transmits target data to the second terminal, the second network connection established with the second terminal is found in the kernel space through the socket; after the target data is transmitted to the kernel space through the first network connection established with the first terminal, the target data is directly transmitted to the second terminal through the second network connection. In this way, the network connection of each terminal can be uniquely marked through the socket, the network connection can be determined in the kernel space through the socket, and the data can be transmitted from the kernel space without reporting to the application layer or waiting for the application layer to call, thus improving the efficiency of data transmission.

[0037] As an optional example, such as Figure 3 As shown, recording network connections and sockets in kernel mode includes:

[0038] S302, for each socket as the current socket, perform the following operations: determine the current socket as the main socket, determine other sockets besides the current socket as child sockets of the current socket, determine a combination of a main socket and multiple child sockets as a group of sockets, and record it in a table; or, connect all sockets to the same socket center, and record the combination of sockets and socket centers in kernel mode, where the socket center is used to mark multiple terminals.

[0039] In this embodiment, different methods can be used to record sockets. One method is to treat each socket as a primary socket and the other sockets as child sockets, recording the association between the primary socket and the other child sockets to obtain a group of sockets, which are then recorded in a table. Each socket is recorded as a primary socket, resulting in multiple tables. Another method is to record sockets as a group using pointers, with this group of sockets connected to the same socket center, and the pointers recording the order. Each time a socket is added, a pointer is added. The socket center is used to mark multiple terminals participating in the network connection.

[0040] As an optional example, recording network connections and sockets in kernel mode includes: in the event that a third network connection with a third terminal among multiple terminals is disconnected, deleting the third socket of the third network connection from kernel mode, wherein, in the case that the third socket of the third network connection is not included in kernel mode, when transmitting first data to the third terminal, sending a notification message for transmitting the first data to user mode.

[0041] In this embodiment, after the intermediate device establishes a network connection with the terminal, it can record the socket of the network connection in kernel mode. When transmitting data, it checks whether there is a corresponding network connection by searching the socket in kernel mode. Therefore, when the network connection is broken, the socket in kernel mode must be deleted. As a result, when transmitting data, since the corresponding socket cannot be found, data cannot be transmitted directly from kernel mode.

[0042] As an optional example, such as Figure 4 As shown, when the first terminal among multiple terminals transmits target data to the second terminal, the process of locating the second network connection established with the second terminal in kernel mode via sockets includes:

[0043] S402, the first socket of the first network connection established with the first terminal is used as the main socket, and the target socket combination is found from the socket combination, wherein the main socket of the target socket combination is the first socket;

[0044] S404, Locate the second socket for the second network connection from the sub-sockets of the target socket combination;

[0045] S406, if a second socket is found, determine that a second network connection has been found.

[0046] This embodiment describes how to find the second network connection when recording a socket using a primary socket and a secondary socket.

[0047] Since the first terminal is sending target data to the second terminal, the first socket can be determined first through the first network connection between the first terminal and the intermediate device. Then, based on the first socket, the second socket is searched for in a socket combination where the first socket is the primary socket. The second socket is the socket for the second network connection established between the second terminal and the intermediate device. If this socket can be found, it is determined that a second network connection exists, and the target data can be transmitted through the second network connection.

[0048] As an optional example, such as Figure 5 As shown, when the first terminal among multiple terminals transmits target data to the second terminal, the process of locating the second network connection established with the second terminal in kernel mode via sockets includes:

[0049] S502, starting from the starting point of the socket center, traverse each socket element connected to the socket center in sequence, wherein each socket element includes the socket center, the socket, and a pointer to the next socket element;

[0050] S504, if the second socket of the second network connection is found during traversal, it is determined that the second network connection has been found.

[0051] This embodiment describes how to find the second network connection when recording a socket using a socket-centric approach.

[0052] When locating a second network connection, the second socket of the second network connection is first determined. This second socket is recorded in kernel mode when the second terminal establishes the second network connection with the intermediate device. Multiple terminals involved in parameter network transmission correspond to a socket center, which can be used to identify these multiple terminals, for example, by combining the terminal identifiers of multiple terminals. Each socket can be connected to this socket center as a socket element. A socket element includes the socket center, the socket, and a pointer. The socket elements are ordered using pointers. Starting from the first socket element in the socket center, it checks if the socket within it is the second socket, and so on, searching the socket elements sequentially. If the second socket is found, it is confirmed that a second network connection exists. If the second network connection is broken, the socket element containing the second socket is deleted, and the second socket can no longer be found.

[0053] As an optional example, after the target data is transmitted to the kernel mode through the first network connection established with the first terminal, directly transmitting the target data to the second terminal through the second network connection includes: calling a read function to read the target data in the first network connection; and, if the target data is read, calling a write function to write the target data into the send function of the second network connection.

[0054] In this embodiment, the kernel state includes a read function and a write function. When the first terminal transmits the target data to the kernel state through the first network connection, the kernel state reads the target data through the read function and writes it into the send function of the second network connection, so that the target data is directly sent from the kernel state to the second terminal.

[0055] When the target data is transmitted through the first network connection, it is recorded in the sending function of the first network connection. The kernel reads the data from the sending function of the first network connection through the reading function.

[0056] As an optional example, after the target data is transmitted to the kernel mode through the first network connection established with the first terminal, and after the target data is directly transmitted to the second terminal through the second network connection, the above method further includes: recording the service identifier of the target data, the terminal identifier of the first terminal, the terminal identifier of the second terminal, the first socket of the found first network connection, and the second socket of the second network connection into the log.

[0057] In this embodiment, if the kernel sends the target data but does not report it to the upper application layer, the application layer will be unaware of it. Therefore, it is necessary to record the target data sent by the kernel and the associated information when sending the target data, such as the service identifier of the target data, the terminal identifier of the first terminal, the terminal identifier of the second terminal, the first socket of the first network connection found, and the second socket of the second network connection. All of these should be recorded in the log so that the log can be reported periodically or the user can call the log to view the sent target data.

[0058] above Figure 2 The following scenario is illustrated with examples. An intermediate device can establish network connections with terminals A and C, and these connections can be TCP connections. System function interfaces create sockets (TCP socket socks) and service IDs for the established network connections. The service ID identifies the upper-layer service, and the socket uniquely identifies the network connection. The established network connection and socket are recorded in kernel mode. When the kernel receives transmitted data from terminal A via the `tcp_recvmsg` function, it searches for the kernel mode of terminal C in the socket records using the system function `sockfd_lookup_light`. If the kernel mode of terminal C is found, it indicates that a network connection has been established between the intermediate device and terminal C, and data is sent via the `tcp_sendmsg` function. When data transmission is complete or the terminal's network connection is closed, logs are logged, including the found socket record, the data sent, and the identifiers of the sender and receiver.

[0059] Figure 6 This is a schematic diagram of a data transmission device provided in an embodiment of this application. Figure 6 As shown, the above-mentioned data transmission device includes:

[0060] The connection module 602 is used to establish a network connection with each of the multiple terminals in user mode and set a socket for each network connection, wherein the socket is used to uniquely identify the network connection;

[0061] Recording module 604 is used to record network connections and sockets in kernel mode;

[0062] The lookup module 606 is used to look up the second network connection established with the second terminal in the kernel mode through a socket when the first terminal among multiple terminals transmits target data to the second terminal.

[0063] The transmission module 608 is used to transmit the target data directly to the second terminal through the second network connection after the target data has been transmitted to the kernel state through the first network connection established with the first terminal.

[0064] The aforementioned terminals can be terminals running applications, and applications on different terminals can communicate with each other through an intermediary device. For example... Figure 2 In the scenario shown, the intermediate device includes kernel mode and user mode. When the target data is being transmitted, terminal A transmits the target data to the kernel mode of the intermediate device, and the kernel mode directly transmits the target data to terminal B.

[0065] The aforementioned intermediate device can establish a network connection with each participating terminal and assign a socket to each network connection, which uniquely identifies the connection. This network connection and socket can be recorded in kernel mode. When the first terminal transmits target data to the second terminal, the target data first reaches kernel mode through the first network connection between the first terminal and the intermediate device. Then, the second network connection between the intermediate device and the second terminal is located using the socket recorded in kernel mode. The target data is then directly transmitted to the second terminal through this second network connection without waiting for an application layer call.

[0066] The solution provided in this application establishes a network connection between the user space and each of the multiple terminals, and sets a socket for each network connection, wherein the socket is used to uniquely identify the network connection; the network connection and the socket are recorded in the kernel space; when the first terminal transmits target data to the second terminal, the second network connection established with the second terminal is found in the kernel space through the socket; after the target data is transmitted to the kernel space through the first network connection established with the first terminal, the target data is directly transmitted to the second terminal through the second network connection. In this way, the network connection of each terminal can be uniquely marked through the socket, the network connection can be determined in the kernel space through the socket, and the data can be transmitted from the kernel space without reporting to the application layer or waiting for the application layer to call, thus improving the efficiency of data transmission.
