[0041] It is understandable that the above notification and the process of obtaining user authorization are merely illustrative and do not constitute a limitation on the implementation of the present disclosure. Other methods that meet relevant laws and regulations may also be applied to the implementation of the present disclosure.

[0042] The BBR (Bottleneck Bandwidth and Round-trip propagation time) algorithm is a congestion control algorithm. By running the BBR algorithm, the data transmission device can detect the actual network bandwidth and minimum round-trip delay of the network, and dynamically adjust the data transmission rate based on the detected actual network bandwidth and minimum round-trip delay to maximize the utilization of network bandwidth. Figure 1 , which is a schematic diagram of the state machine jump of the BBR algorithm. Figure 1 The state machine of the BBR algorithm mainly includes the STARTUP state, the DRAIN state, the PROBE_BW (ProbeBandwidth, bandwidth detection) state and the PROBE_RTT (Probe Round-Trip Time, round-trip delay detection) state. Among them:

[0043] The STARTUP state can also be called the startup state. In this state, the data sending device can set the sending rate gain and the sending window gain of the data sending to a larger value, so as to quickly increase the data sending rate and the sending window size. As the data sending rate and the sending window size increase, the data sending device can determine the actual network bandwidth based on the data transmission volume and the data transmission time. If the actual network bandwidth determined for three consecutive times does not change, it means that the maximum network bandwidth (i.e., the network bottleneck) has been reached. In this case, it can jump to the DRAIN state.

[0044] The DRAIN state is also called the drain state. In this state, the data sending device can set the data transmission rate gain and the transmission window gain to smaller values, so as to reduce the data transmission rate and try to drain the data that is still transmitted in the network in the STARTUP state. During the draining process, if the amount of data transmitted in the network is less than the data volume threshold, it can jump to the PROBE_BW state.

[0045] The PROBE_BW state is also called the bandwidth detection state. This state can be further divided into sub-states such as PROBE_UP, PROBE_DOWN, and PROBE_USE. In each sub-state, the sending rate gain and the sending window gain may not be exactly the same. In this way, the data sending rate is periodically increased and decreased to detect the new maximum network bandwidth. When the duration of the PROBE_BW state exceeds the duration threshold, it can jump to the PROBE_RTT state.

[0046] The PROBE_RTT state is also called the round-trip delay detection state. In this state, the sending rate gain and the sending window gain can be set to 1 to ensure that the data sending device can send data at a stable sending rate and sending window size, thereby detecting the minimum round-trip delay of network data transmission. Based on the detected minimum round-trip delay, it can be determined to jump to the STARTUP state or the PROBE_BW state.

[0047] It should be noted that, in the above STARTUP state, DRAIN state, PROBE_BW state and PROBE_RTT state, if certain conditions are met, it is also possible to directly jump from the STARTUP state to the PROBE_RTT state, or from the DRAIN state to the PROBE_RTT state, or from the PROBE_BW state to the PROBE_RTT state. For example, in any of the STARTUP, DRAIN and PROBE_BW states, if the minimum round-trip delay detected by the data sending device for 10 consecutive seconds does not change, it can jump to the PROBE_RTT state to re-detect the minimum round-trip delay.

[0048] Based on the above description, it can be known that in the state machine jump process of the BBR algorithm, the jump is made when the specified conditions are met. For example, if the actual network bandwidth detected by the data sending device for three consecutive times has not changed, it jumps from the STARTUP state to the DRAIN state; for another example, if the duration of the data sending device in the PROBE_BW state exceeds the duration threshold, it jumps from the PROBE_BW state to the PROBE_RTT state. However, these specified conditions for triggering the jump do not take into account the data transmission requirements of the data acquisition device. For example, when the data acquisition device obtains a video file from the data sending device and plays the video, it may hope that the delay is smaller; when the data acquisition device downloads a file from the data sending device, it may hope that the average download speed is faster. The data transmission rate determined by the current state machine jump conditions of the BBR algorithm cannot meet these requirements of the data acquisition device, that is, the data transmission rate determined by the data sending device based on the BBR algorithm cannot match the actual business scenario.

[0049] In view of this, the present disclosure first provides a data transmission control method, which can improve the matching degree between the data transmission rate and the business scenario. The data transmission control method can be applied to data transmission devices. The data transmission devices include but are not limited to servers, tablet computers, laptops, desktop computers, etc. Figure 2 , which is a flow chart of a data transmission control method provided by an embodiment of the present disclosure. Figure 2 In the data transmission control method, the data transmission control method comprises the following steps:

[0050] Step S21: receiving a data acquisition request, where the data acquisition request includes a target network bandwidth required by a data acquisition device to acquire target data.

[0051] Specifically, the target data may be a video file, picture, text file, etc. that the data acquisition device needs to acquire from the data transmission device. For different types of files, the data acquisition device may have different data transmission requirements (as mentioned above, which will not be repeated here). The target network bandwidth may be the ideal network bandwidth determined by the data acquisition device based on the actual data transmission requirements.

[0052] After the data sending device obtains the data acquisition request, if the BBR algorithm is running in any of the STARTUP state, the DRAIN state and the PROBE_BW state, it can continue to execute steps S22 to S24.

[0053] Step S22: Send target data to the data acquisition device based on the initial sending rate and the first sending rate gain.

[0054] Specifically, the initial transmission rate and the first transmission rate gain may be the initial transmission rate and the first transmission rate gain corresponding to the current target state in the BBR algorithm. The target state is one of the STARTUP state, the DRAIN state, and the PROBE_BW state.

[0055] For example, when the target state is the STARTUP state, the initial sending rate can be a pre-set fixed value, or a value determined based on the actual network state between the data sending device and the data acquisition device. The first sending rate gain can be the sending rate gain corresponding to the STARTUP state. For another example, when the target state is the DRAIN state, the initial sending rate can be the data sending rate when jumping out of the STARTUP state, and the first sending rate gain can be the sending rate gain corresponding to the DRAIN state. For another example, when the target state is the PROBE_BW state, the current target sub-state can be further determined. The initial sending rate can be the data sending rate corresponding to jumping out of the previous sub-state of the target sub-state. The first sending rate gain can be the sending rate gain corresponding to the target sub-state.

[0056] Step S23: in the process of sending the target data to the data acquisition device according to the first sending rate gain, determining the actual network bandwidth between the local device and the data acquisition device.

[0057] Specifically, the data sending device can detect the target data transmission volume within the specified time, and determine the actual network bandwidth between the local device and the data acquisition device based on the detected target data transmission volume. For example, the target data transmission volume is divided by the specified time, and the result can be used as the actual network bandwidth.

[0058] Step S24: When the actual network bandwidth reaches the target network bandwidth, the target data is sent to the data acquisition device according to the second sending rate gain.

[0059] The second transmission rate gain may be a transmission rate gain corresponding to the next state of the target state. In simple terms, when it is detected that the actual network bandwidth reaches the target network bandwidth, the target state is jumped to the next state of the target state.

[0060] It can be seen from step S24 that the technical solution of the present disclosure has improved the BBR algorithm. In the STARTUP state, DRAIN state and PROBE_BW state, the jump between different states can be triggered by the target network bandwidth in the data acquisition request. Therefore, when the transmission rate of the target data is controlled based on the BBR algorithm, it can be ensured that the actual network bandwidth between the data sending device and the data acquisition device can meet the data transmission requirements of the data acquisition device as much as possible. In this way, the data sending rate determined based on the BBR algorithm can be a rate that matches the business scenario.

[0061] In the scheme disclosed in the present invention, it can be understood that when the original jump condition of the BBR algorithm has not been met (for example, the actual network bandwidth has not been detected to be unchanged for three consecutive times), if the actual network bandwidth reaches the target network bandwidth, the current target state is exited in advance, and the next state of the target state is entered in advance. In this way, the actual network bandwidth between the data sending device and the data acquisition device is guaranteed to be the target network bandwidth that meets the data transmission requirements as much as possible. For ease of understanding, for example. Assuming that in the STARTUP state, the actual network bandwidth reaches the target network bandwidth, but the actual network bandwidth has not been detected to be unchanged for three consecutive times, if the STARTUP state is not exited in advance, then under the larger transmission rate gain corresponding to the STARTUP state, the transmission rate of the target data will also increase. At this time, the data transmitted in the network will also increase, and the actual network bandwidth between the data sending device and the data acquisition is also likely to deviate further and further from the target network bandwidth, thereby failing to meet the data transmission requirements of the data acquisition device.

[0062] It should be noted that in steps S22 to S24 of the present disclosure, since the actual network bandwidth detection between the data sending device and the data acquisition device is involved, and the PROBE_RTT state of the BBR algorithm is used to detect the minimum round-trip delay of the network (not directly detecting the actual network bandwidth), therefore, the steps in steps S22 to 24 can be based on the STARTUP state, DRAIN state and PROBE_BW state in the BBR algorithm. In short, after executing step S21, if the BBR algorithm runs in any of the STARTUP state, DRAIN state and PROBE_BW state, steps S22 to S24 can be executed, and steps S22 to S24 can be repeated and executed in a loop, that is, each time the STARTUP state, or DRAIN state, or PROBE_BW state is entered, steps S22 to S24 can be executed once until the target data is sent.

[0063] For example, assuming that after executing step S21, the BBR algorithm is running in the STARTUP state, the specific execution process of steps S22 to S24 can be as follows:

[0064] 11) Based on the initial transmission rate and transmission rate gain corresponding to the STARTUP state, send the target data to the data acquisition device;

[0065] 12) in the process of sending the target data to the data acquisition device, determining the actual network bandwidth between the local device and the data acquisition device;

[0066] 13) When the actual network bandwidth reaches the target network bandwidth, the target data is sent to the data acquisition device according to the transmission rate gain corresponding to the DRAIN state.

[0067] After the above steps 11) to 13), the BBR algorithm enters the DRAIN state. At this time, steps S22 to S24 can be continued, and the specific process can be as follows:

[0068] 21) sending target data to the data acquisition device based on the initial sending rate and the sending rate gain corresponding to the DRAIN state;

[0069] 12) in the process of sending the target data to the data acquisition device, determining the actual network bandwidth between the local device and the data acquisition device;

[0070] 13) When the actual network bandwidth reaches the target network bandwidth, the target data is sent to the data acquisition device according to the sending rate gain corresponding to the PROBE_BW state.

[0071] And so on.

[0072] In summary, in the technical solutions of some embodiments of the present disclosure, based on the target network bandwidth required by the data acquisition device when acquiring the target data, to trigger the switch between different transmission rate gains, it is possible to ensure that the actual network bandwidth between the data acquisition device and the data transmission device meets the data transmission requirements as much as possible. In other words, the time point for triggering the switching of the transmission rate gain based on the target network bandwidth is in line with the actual business scenario, so the data transmission rate determined based on the transmission rate gain before and after the switch is also more in line with the actual business scenario, thereby improving the matching degree between the data transmission rate and the business scenario.

[0073] In some embodiments, corresponding to the above step S24, if the actual network bandwidth does not reach the target network bandwidth, and the network status between the data sending device and the data acquiring device reaches the preset network status, the method of the present disclosure may further include:

[0074] The target data is sent to the data acquisition device according to the second sending rate gain.

[0075] Specifically, the preset network state may be a network state when the BBR algorithm before improvement triggers a state jump, and may specifically include one or more of the following network states:

[0076] 31) The actual network bandwidth reaches the maximum network bandwidth between the data sending device and the data acquiring device. This network state is the trigger condition for the BBR algorithm to jump from the STARTUP state to the DRAIN state before the improvement.

[0077] 32) The amount of data in transit between the data sending device and the data acquisition device is less than the quantity threshold. The amount of data in transit refers to the amount of data being transmitted in the network between the data sending device and the data acquisition device. This network state is the trigger condition for the BBR algorithm to jump from the DRAIN state to the PROBE_BW state before the improvement.

[0078] 33) The duration of sending the target data to the data acquisition device according to the first transmission rate gain reaches the duration threshold. This network state is the trigger condition for the BBR algorithm before improvement to jump from the PROBE_BW state to the PROBE_RTT state.

[0079] Simply put, when the actual network bandwidth has not yet reached the target network bandwidth, if the jump condition of the BBR algorithm before the improvement has been met, it is necessary to jump in time to avoid network congestion.

[0080] In the above embodiment, the jump is started when the actual network bandwidth has not yet reached the target network bandwidth. It can be understood that when the actual network status between the data acquisition device and the data sending device has not yet reached the ideal target network bandwidth, the status jump is performed in time based on the jump condition of the BBR algorithm before improvement, which can avoid network congestion and prevent the network status from further deteriorating.

[0081] In some embodiments, corresponding to the above step S24, if the actual network bandwidth does not reach the target network bandwidth, and the network status between the data sending device and the data acquiring device does not reach the preset network status, the method of the present disclosure may further include:

[0082] Continue to send the target data to the data acquisition device according to the first sending rate gain.

[0083] In this way, the actual network bandwidth between the data sending device and the data acquiring device can be controlled to be as close to the target network bandwidth as possible, so as to obtain the target network bandwidth that meets the data transmission requirements.

[0084] In some embodiments, based on the acquired data acquisition request, the method of the present disclosure may further include:

[0085] Determine the target transmission protocol corresponding to the data acquisition request;

[0086] Determining a target storage location of a target network bandwidth in a data acquisition request according to a protocol format of a target transmission protocol;

[0087] Get the target network bandwidth from the target storage location.

[0088] Specifically, since different transmission protocols may have different protocol formats, the storage location of the target network bandwidth in the data acquisition request may be different in the data acquisition request transmitted based on different transmission protocols. For example, when the target transmission protocol is a TCP (Transmission Control Protocol)-like protocol, the target network bandwidth may be obtained from the HTTP (HyperText Transfer Protocol) request header of the data acquisition request. When the target transmission protocol is a QUIC (Quick UDP Internet Connections)-like protocol, the target network bandwidth may be obtained from the QUIC frame of the data acquisition request.

[0089] In the above embodiment, the target network bandwidth is stored at different locations of the data acquisition request based on different transmission protocols, which has better adaptability.

[0090] Corresponding to the above data transmission control method, the present disclosure also provides a data acquisition method. The data acquisition method can be applied to a data acquisition device. The data acquisition device includes but is not limited to a tablet computer, a laptop computer, a desktop computer, etc. Figure 3 , which is a flow chart of a data acquisition method provided by an embodiment of the present disclosure. Figure 3 In the method, the data acquisition method comprises the following steps:

[0091] Step S31, in response to generating a data acquisition instruction, determining target data to be acquired and data transmission requirements of the target data during transmission.

[0092] Specifically, when a preset operation occurs in the data acquisition device, a data acquisition instruction may be generated. The data acquisition instruction may be used to specify the target data to be acquired. For example, when a button associated with video file A in the data acquisition device is triggered, a data acquisition instruction may be generated to acquire video file A from the data sending device.

[0093] Data transmission requirements refer to the transmission conditions that the target data must meet during the transmission process, such as the transmission rate and transmission delay that must be met. Specifically, after determining the target data, the data attributes of the target data can be determined, and based on the data attributes, the data transmission requirements can be determined. Among them, the data attributes may include but are not limited to the data type of the target data (such as video files, text files, pictures, etc.), the size of the data, etc. Based on the above description, it can be seen that due to the different data attributes of target data, different transmission conditions may be required (for example, when playing video files online, a lower delay is required; when downloading files, a higher average transmission rate is required). Therefore, the data transmission requirements of the target data can be determined first based on the data attributes of the target data.

[0094] Step S32: determining the target network bandwidth required for the target data during transmission according to the data transmission requirement.

[0095] Specifically, for example, for video files that require a lower delay, the file size of the video file can be divided by the required delay to obtain the target network bandwidth. For another example, for text files that require a higher download rate, the required maximum file download rate can be used as the target network bandwidth.

[0096] Step S33, construct a data acquisition request including the target network bandwidth, and send the data acquisition request to the data sending device. The data sending device is used to determine the actual network bandwidth between the local and the data acquisition device during the process of sending the target data at the first sending rate gain, and send the target data at the second sending rate gain when the actual network bandwidth reaches the target network bandwidth.

[0097] Specifically, similar to the above-mentioned data transmission control method, the protocol format of the target transmission protocol can be determined according to the target transmission protocol corresponding to the data acquisition request; and based on the protocol format, the target storage location of the target network bandwidth in the data acquisition request can be determined; and the target network bandwidth can be written into the target storage location.

[0098] The data acquisition method disclosed in the present invention has the same technical features as the data transmission control method, and therefore has the same beneficial effects as the data transmission control method, which will not be described in detail herein.

[0099] Corresponding to the data transmission control method, the present disclosure also provides a data transmission control device. Figure 4 , which is a module schematic diagram of a data transmission control device provided in some embodiments of the present disclosure.

[0109] The amount of data in transit between the data sending device and the data acquiring device is less than a quantity threshold;

[0110] The duration for sending the target data to the data acquisition device according to the first sending rate gain reaches a duration threshold.

[0111] In some embodiments, if the actual network bandwidth does not reach the target network bandwidth, and the network status between the data sending device and the data acquiring device does not reach the preset network status, the policy switching module 404 is further used to:

[0112] Continue to send the target data to the data acquisition device according to the first sending rate gain.
