Fig. 4 is a schematic flowchart of an example of a data transmission method provided in an embodiment of the present application, where the method includes:

s101, acquiring first configuration information; the first configuration information is used for representing flow control operation required by the electronic equipment when data is transmitted.

Specifically, in the process of developing a WLAN chip driver by research personnel, different flow control operations can be selected through function interfaces corresponding to the different flow control operations, so as to form first configuration information; wherein, the different flow control operations comprise executing different data processing on the data to be transmitted so as to achieve different flow control effects. The method can be applied to the electronic equipment after the WLAN chip driver is developed, and the first configuration information can be obtained after the electronic equipment is started under normal conditions.

It should be noted that the flow control operation may include a data processing procedure provided in this embodiment, may also include a data processing procedure provided by a WLAN chip manufacturer, and may also be a combination of two (or more) data processing procedures, so long as a corresponding function interface can be provided for a developer. In the development process, research and development personnel only need to select different flow control operations according to own needs, and do not need to redevelop different flow control operation processes. It should also be noted that the above configuration process may be applicable to electronic devices of the light device or rich device class.

And S102, if the first configuration information carries the identifier of the first flow control operation, the electronic equipment executes the first flow control operation on data to be transmitted when transmitting the data.

Alternatively, the first and second electrodes may be,

s103, if the first configuration information carries the identifier of the second flow control operation, the electronic equipment executes the second flow control operation on the data to be transmitted when transmitting the data.

Specifically, the flow control operation has a corresponding identifier, and the identifier may be a function name of a function interface corresponding to the flow control operation, or other identifiers that can distinguish different flow control operations. After the electronic equipment acquires the first configuration information, the identification carried by the first configuration information can be judged by analyzing the first configuration information; if the first configuration information carries the identifier of the first flow control operation, the electronic device executes the first flow control operation on the data to be transmitted when transmitting the data, and if the first configuration information carries the identifier of the second flow control operation, the electronic device executes the second flow control operation on the data to be transmitted when transmitting the data, wherein the first flow control operation and the second flow control operation correspond to different data processing processes.

As shown in fig. 5, the electronic device, when transmitting data, executes a first flow control operation on data to be transmitted, including:

s201, storing the data to be transmitted into a corresponding scheduling queue according to the transmission priority of the data to be transmitted; the transmission priority of the data to be transmitted is determined according to the data type of the data to be transmitted.

Specifically, the electronic device may determine a corresponding transmission priority according to a data type of the data to be transmitted, for example, the transmission priority of the video data is greater than the transmission priority of the voice data, and then store the data to be transmitted in a corresponding scheduling queue according to the transmission priority. Optionally, there may be only one scheduling queue, and the data to be transmitted are enqueued in sequence according to the transmission priority; the number of the scheduling queues can be multiple, each transmission priority corresponds to one scheduling queue, and the data to be transmitted is stored in the scheduling queue corresponding to the transmission priority according to the transmission priority.

Optionally, the data to be transmitted may further include at least one of a data frame, a management frame, and a chip control command, and the electronic device may further determine a transmission priority of the data frame or the management frame according to a priority in a TCP \ IP packet priority (TOS) or UDP \ TCP packet header custom field. The management frame refers to a communication management frame between the network chip driver and the network peer according to the network protocol, for example, the management frame in the 802.11 protocol includes a disassociation frame (disassociation) and a deauthentication frame (deauthentication).

Optionally, before the electronic device stores the data to be transmitted in the corresponding scheduling queue, the transmission priority of the data to be transmitted may also be determined according to the data type of the data to be transmitted and the corresponding relationship between the preset data type and the transmission priority. For example, the preset correspondence between the data types and the transmission priorities may be stored in the database in the form of a data table.

S202, according to the preset scheduling priority of the scheduling queue, dequeuing and scheduling the data to be transmitted.

Specifically, each scheduling queue may also correspond to its own scheduling priority, and when the electronic device needs to schedule data to be transmitted in the scheduling queue, the electronic device may dequeue and schedule the data to be transmitted according to the scheduling priority.

Optionally, when there is only one scheduling queue, the data to be transmitted is directly dequeued in a first-in first-out manner.

And S203, controlling the flow of the dequeued data to be transmitted, and sending the data to be transmitted after the flow is controlled to a target interface.

Specifically, after the data to be transmitted is dequeued, the electronic device may further perform flow control on the dequeued data to be transmitted, so as to avoid that the data to be transmitted greatly affects other working performances of the electronic device, and send the data to be transmitted after the flow control to the target interface, so as to perform data transmission.

Optionally, before storing the data to be transmitted in the corresponding scheduling queue, the electronic device may further perform format conversion on the data to be transmitted according to a preset data format, so as to standardize a network data format, reduce the number of data copies, and further improve transmission efficiency. The preset data format may be as shown in fig. 6, and includes a doubly linked list, a buffer segment, a memory buffer address, and a memory buffer length field, where the memory buffer address is a buffer address of each segment in the buffer segment. The specific definition mode can be as follows:

according to the data transmission method, the priority scheduling and the flow control are carried out on the data to be transmitted, a unified flow control mechanism is formed, the data transmission performance can be improved, and the experience degree of a user when the user uses the electronic equipment is improved.

In a possible implementation manner, the method for controlling flow of dequeued data to be transmitted in S203 may include, but is not limited to: calculating the flow rate corresponding to the data to be transmitted according to the flow of the data to be transmitted; and if the flow rate corresponding to the data to be transmitted is greater than or equal to a preset flow rate threshold value, performing flow shaping on the data to be transmitted.

Specifically, the flow rate of the data to be transmitted may be a data volume, and the electronic device may calculate a flow rate corresponding to the data to be transmitted according to the data volume and the transmission duration; if the flow rate is greater than or equal to a preset flow rate threshold (e.g., 20 ms), the electronic device needs to perform traffic shaping on the data to be transmitted. Optionally, the algorithm used for traffic shaping may be a leaky bucket algorithm, a token bucket algorithm, or the like, so as to limit the flow rate of the data to be transmitted, and further improve the transmission performance. Optionally, if the traffic of the data to be transmitted is greater than or equal to a preset traffic threshold (e.g., 200 megabytes), the electronic device may also schedule available hardware resources in the electronic device according to a preset hardware scheduling rule, so as to avoid problems of congestion, delay and the like caused when the electronic device transmits the data to be transmitted; by way of example and not limitation, this may include increasing the frequency of secure digital input and output cards (secure digital input and output), running CPU large cores, multi-threaded running, etc.

In a possible implementation manner, aiming at the currently popular electronic device operating systems, such as a Linux system, a real-time operating system RTOS and the like, a WLAN driver developed by the Linux electronic device only supports docking with a network layer on Linux, and is high in cost and incapable of being reused when being transplanted to other platforms; the WLAN driver on the RTOS directly interfaces with the protocol stack, and the modification of the protocol stack may bring about modification of the driver, increase maintenance cost, and is not easy to be transplanted to another operating system, and reusability is poor. To solve this problem, referring to fig. 1, the management module in the network device layer of this embodiment may determine a network protocol that needs to be used for transmitting data according to configuration information (referred to as second configuration information) of the decision module, where the second configuration information is formed according to a network protocol type selected by a developer in a process of developing a WLAN chip driver, that is, the developer may select a corresponding network protocol according to an operating system type of an electronic device to which the WLAN chip is to be applied in a process of developing the WLAN chip driver, so as to form the second configuration information. After the electronic device is started, the second configuration information can be obtained, the network protocol adopted by the electronic device for transmitting the data to be transmitted is determined by analyzing the second configuration information, and the data to be transmitted is transmitted by using the network protocol. In the method, research personnel only need to select different network protocols according to actual requirements to generate second configuration information, so that convenience is further provided for the research personnel in the WLAN chip drive development process, and meanwhile, the difference of network layers among different electronic devices can be shielded, and the multiplexing on the different electronic devices is realized.

In a possible implementation manner, the electronic device may include a network chip (WLAN chip) and a flow control module, where the flow control module and a chip driver are both in a kernel state, and data interaction therebetween is directly isomorphically transferred through a pointer, as shown in fig. 7, where the data transmission method may include:
