[0042] Figure 1 This is a flowchart illustrating a data download process control method provided in an embodiment of the present disclosure. This embodiment is applicable to scenarios involving data transmission process management. The method can be executed by a data download process control device, which can be implemented in software and / or hardware. Optionally, the data download process control device can be implemented by an electronic device, such as a mobile terminal, a PC, or a server.
[0043] like Figure 1 As shown, the data download process control method includes:
[0044] S110. Obtain the actual network state parameters during the download of the first data segment.
[0045] The first data segment is any data segment of the target data download object that is in the downloading state.
[0046] Typically, during data downloads, especially for large datasets, the entire dataset is not downloaded at once. Instead, multiple data segments are downloaded sequentially to alleviate memory pressure during the download process.
[0047] Network status refers to the overall operating condition of a network at a certain moment. Status data such as whether the network connection is normal, whether the network equipment is working properly, and the degree of network congestion can be used to characterize network quality.
[0048] The real network status parameters are the real network status parameters obtained during the download of the first data segment, which represent the network status during the data download process based on the data transmission protocol configuration for downloading the first data segment.
[0049] S120. Based on the preset mapping relationship between the receive buffer size and network status parameters, determine the reference network status data under different receive buffer parameter configurations.
[0050] In the process of data downloading, it was found that different terminal operating systems have different receive buffer configurations that affect network performance during data transmission based on the TCP protocol (Transmission Control Protocol).
[0051] The preset mapping relationship between receive buffer size and network status parameters can be determined by obtaining network status measurement results during actual data download, and then performing statistical analysis based on the measurement results. For example... Figure 2 and Figure 3 The diagrams shown below illustrate the preset mapping relationship between the receive buffer size and network status parameters. Figure 2 This is a preset mapping relationship between TCP receive buffer size and average speed (bandwidth). Figure 3 A preset mapping relationship between TCP receive buffer size and network latency (Round-Trip Time, RTT).
[0052] The impact of receive buffering on network quality can be divided into two aspects: transmission speed and latency, and there is a trade-off between these two. During data download, increasing the receive buffer will increase speed but increase latency; conversely, speed will decrease but latency will decrease. Therefore, it is necessary to adjust the receive buffer to find the optimal balance between bandwidth and latency, thereby achieving the best overall network service quality.
[0053] Different receive buffer parameter configurations can be any receive buffer size value within the predicted buffer size configuration range. During the process of determining the control parameters during data download, it is necessary to iterate through each configurable receive buffer size value.
[0054] For each configurable receive buffer size, the network status parameter corresponding to each configurable receive buffer size can be found in the preset mapping relationship between receive buffer size and network status parameters, thus obtaining the reference network status data for different receive buffer parameter configurations.
[0055] S130. Based on the actual network state parameters and the reference network state parameters, determine the estimated network state parameters for downloading the second data segment based on different receive buffer sizes.
[0056] The second data segment is the next data segment adjacent to the first data segment in the target data download object. After downloading the first data segment, the second data segment can be downloaded based on a TCP request for the second data segment.
[0057] It can be understood that this refers to the size of the TCP receive buffer when downloading the first data segment, or it can be one of the different receive buffer size configurations.
[0058] Therefore, the reference network state parameters and the actual network state parameters corresponding to the size of the TCP receive buffer when downloading the first data segment are known.
[0059] The system can establish a numerical relationship, such as the change in buffer size or a proportional value, between different receive buffer sizes and the TCP receive buffer size when downloading the first data segment. Within a pre-defined mapping, it can determine the change in network state parameters when the buffer size changes from one size to another. Based on the actual network state parameters, and then using this change, it can obtain the estimated network state parameters for downloading the second data segment.
[0060] S140. Based on the estimated network state parameters, calculate the estimated download time for downloading the second data segment according to different receive buffer size configurations.
[0061] Based on the estimated network state parameters and the data size of the second data segment under different receive buffer size configurations, the estimated download time for downloading the second data segment can be calculated. The download time can be calculated by dividing the total data volume by the download speed. The download speed can be determined based on the estimated network state parameters.
[0062] S150. Set the receive buffer size corresponding to the shortest estimated download duration as the receive buffer size when downloading the second data segment.
[0063] After the first data segment is downloaded, when downloading the second data segment, the receive buffer size corresponding to the shortest estimated download time can be set as the receive buffer size when downloading the second data segment, thereby controlling the data download process to adapt to network conditions.
[0064] In this embodiment, the actual network state parameters during the download of the first data segment are obtained; wherein the first data segment is any data segment of the target data download object that is in the download state; based on the preset mapping relationship between the receive buffer size and the network state parameters, reference network state data under different receive buffer parameter configurations are determined; based on the actual network state parameters and the reference network state parameters, the estimated network state parameters for downloading the second data segment based on different receive buffer size configurations are determined; wherein the second data segment is the next data segment of the target data download object adjacent to the first data segment; based on the estimated network state parameters, the estimated download duration for downloading the second data segment based on different receive buffer size configurations is calculated respectively; the receive buffer size corresponding to the shortest estimated download duration is set as the receive buffer size when downloading the second data segment. The technical solution of this embodiment solves the problem that the receive buffer configuration parameters cannot be flexibly configured, and the receive buffer can be dynamically adjusted during the data download process to reduce the overall data download time.
[0065] Figure 4 This is a flowchart illustrating a data download process control method provided in an embodiment of this disclosure. Based on the above embodiment, it further explains the process of calculating the estimated network state parameters. This method can be executed by a data download process control device, which can be implemented in software and / or hardware, optionally through an electronic device such as a mobile terminal, PC, or server.
[0066] like Figure 4 As shown, the data download process control method includes:
[0067] S210. Obtain the actual network state parameters during the process of downloading the first data segment.
[0068] The first data segment is any data segment of the target data download object that is in the downloading state.
[0069] S220. Based on the preset mapping relationship between the receive buffer size and network status parameters, determine the reference network status data under different receive buffer parameter configurations.
[0070] S230. For each different receive buffer size configuration, based on the receive buffer candidate value corresponding to the different receive buffer size configuration and the reference network state parameter corresponding to the receive buffer configuration value when downloading the first data segment, determine the buffer adjustment coefficient corresponding to each receive buffer candidate value.
[0071] Assume the receive buffer configuration value when downloading the first data segment is represented as recv_buf i Each candidate value in the receive buffer can be represented as recv_bufi+1 Where i represents the sequence number of the first data segment in the target data download object. i+1 represents the sequence number of the second data segment following the first data segment in the target data download object. y i (recv_buf i This refers to the reference network state parameter corresponding to the receive buffer configuration value when downloading the first data segment, y. i+1 (recv_buf i+1 This represents the reference network state parameter corresponding to the receive buffer candidate value. The buffer adjustment coefficient can be expressed as...
[0072] In one optional implementation, based on the candidate receive buffer values configured for different receive buffer sizes and the reference network state parameters corresponding to the receive buffer configuration values when downloading the first data segment, a buffer adjustment coefficient corresponding to each candidate receive buffer value is determined. This can be achieved by first calculating the ratio of the reference network state parameters corresponding to the receive buffer configuration values when downloading the first data segment to the reference network state parameters corresponding to each candidate receive buffer value, corresponding to Tune(recv_buf). i ,recv_buf i+1 Then, based on the prediction error of the historical network state parameter estimation results, each ratio is adjusted to obtain the corresponding ratio adjustment result, and the ratio adjustment result is determined as the buffer adjustment coefficient corresponding to each candidate value of the receive buffer.
[0073] The process of adjusting each ratio based on the prediction error derived from historical network state parameter estimation can be expressed as follows: err k It can be or Where k represents the k-th network parameter prediction performed before downloading the first data segment. β is the time decay coefficient, representing the weight of the historical error reference.
[0074] It is understandable that prediction errors can take other forms, such as mean absolute error, mean square error, and KL hash error. In actual control, it is necessary to correct future predictions while taking historical errors into account. The actual configurations in the above formulas can be constrained and weighted according to the actual application and the device's memory situation to achieve the optimal configuration.
[0075] S240. Based on the buffer adjustment coefficient and the actual network state parameters, determine the estimated network state parameters for downloading the second data segment according to different receive buffer sizes.
[0076] The estimated network state parameters can be expressed as: y i =bandi or rtt i Represents the actual network state parameters.
[0077] S250. Based on the estimated network state parameters, calculate the estimated download time for downloading the second data segment according to different receive buffer size configurations.
[0078] The estimated download time can be calculated based on the bandwidth, data transmission latency, and data size of the second data segment in each estimated network state parameter, thus obtaining the estimated download time for downloading the second data segment based on different receive buffer size configurations.
[0079]
[0080] Among them, T i+1 The size of the second data segment is band. i+1 and band i+1 To predict network state parameters The two parameters in it.
[0081] S260. Set the receive buffer size corresponding to the shortest estimated download duration as the receive buffer size when downloading the second data segment.
[0082] The technical solution of this disclosure involves obtaining real network state parameters during the download of a first data segment; the first data segment is any data segment of the target data download object that is in the download state; based on a preset mapping relationship between the receive buffer size and network state parameters, reference network state data is determined under different receive buffer parameter configurations; for each different receive buffer size configuration, a buffer adjustment coefficient is determined based on the receive buffer candidate value corresponding to the different receive buffer size configuration and the reference network state parameter corresponding to the receive buffer configuration value when downloading the first data segment. Based on the buffer adjustment coefficient and the real network state parameters, estimated network state parameters for downloading a second data segment based on different receive buffer size configurations are determined; based on the estimated network state parameters, estimated download durations for downloading the second data segment based on different receive buffer size configurations are calculated respectively. The receive buffer size corresponding to the shortest estimated download duration is set as the receive buffer size when downloading the second data segment. The technical solution of this disclosure solves the problems of inflexible configuration of receive buffer parameters and how to determine accurate buffer adjustment coefficients. It allows dynamic adjustment of the receive buffer during data download to achieve the best balance between network latency and bandwidth, thereby reducing overall data download time.
[0083] Figure 5This is a flowchart illustrating a data download process control method provided in an embodiment of this disclosure. Based on the above embodiment, the closed-loop control process of the data download process is further explained. This method can be executed by a data download process control device, which can be implemented in software and / or hardware, optionally through an electronic device, such as a mobile terminal, PC, or server.
[0084] like Figure 5 As shown, the data download process control method includes:
[0085] S310. When the first data segment is the first data segment of the target data download object, configure the data download protocol parameters for downloading the first data segment according to the preset receive buffer size value.
[0086] The preset receive buffer size is determined based on the object type of the target data being downloaded. Different object types correspond to different preset receive buffer sizes. For example, the preset receive buffer size when the target data is video data can be larger than the preset receive buffer size when the target data is text data. It can also be set in conjunction with the device's memory size.
[0087] The preset receive buffer size can be used as the initial receive buffer parameter value during the download process of the target data download object, that is, the protocol memory during the data download link startup phase.
[0088] S320. Obtain the actual network state parameters during the download of the first data segment.
[0089] S330. Based on the preset mapping relationship between the receive buffer size and network status parameters, determine the reference network status data under different receive buffer parameter configurations.
[0090] S340. Based on the actual network state parameters and the reference network state parameters, determine the estimated network state parameters for downloading the second data segment based on different receive buffer sizes.
[0091] The second data segment is the next data segment in the target data download object that is adjacent to the first data segment.
[0092] S350. Based on the estimated network state parameters, calculate the estimated download time for downloading the second data segment according to different receive buffer size configurations.
[0093] S360: Set the receive buffer size corresponding to the shortest estimated download duration as the receive buffer size when downloading the second data segment.
[0094] S370. Determine whether the second data segment is the last data segment of the target data download object.
[0095] S380. When the second data segment is not the last data segment of the target data download object, during the download process of the second data segment, update the corresponding data segments of the first and second data segments in the target data download object to continuously control the data download process.
[0096] When the second data segment is not the last data segment of the target data download object, it indicates that the target data download object has not been completely downloaded, and the remaining data segments need to be downloaded. Therefore, during the download of the second data segment, the above steps can be repeated to determine the receive buffer for data segments following the second data segment. Updating the corresponding data segments of the first and second data segments in the target data download object can be done by updating the data segment corresponding to the first data segment in the target data download object to the data segment corresponding to the original second data segment that is currently being downloaded, and updating the data segment corresponding to the second data segment in the target data download object to the next data segment of the original second data segment that is currently being downloaded.
[0097] When the second data segment is the last data segment of the target data download object, the data download protocol parameters are reconfigured according to the preset receive buffer size in order to download the data segment of the new target data download object.
[0098] In a specific application instance where video is the data download object, the protocol receive buffer during the video download initiation phase can be configured first to download the first video segment and measure the initial network state data. Then, based on historical measurement data and the network state parameter prediction implementation method (prediction model) provided in the above embodiments, and using historical errors for prediction correction, the expected download time of the next video segment is obtained. Finally, the TCP receive buffer corresponding to the shortest download time is selected as the control parameter for downloading the next video segment. Based on the adjusted control parameters, the data download of the next video segment is performed. After completion, the actual download speed and latency are recorded and fed back to the prediction model until the entire video data object is downloaded or the download process is terminated. During the data download process based on the data download process control method provided in this embodiment, latency and network speed can be effectively balanced to achieve the shortest overall data download time and optimize the network quality of practical applications. For example, in short video applications, it can effectively alleviate video stuttering and loading time.
[0099] The technical solution of this disclosure embodiment includes the following steps: When the first data segment is the first data segment of the target data download object, the data download protocol parameters for downloading the first data segment are configured according to a preset receive buffer size value, wherein the preset receive buffer size is determined based on the object type of the target data download object; the actual network status parameters during the downloading of the first data segment are obtained; based on a preset mapping relationship between the receive buffer size and the network status parameters, reference network status data is determined under different receive buffer parameter configurations; based on the actual network status parameters and the reference network status parameters, estimated network status parameters for downloading the second data segment are determined based on different receive buffer size configurations; wherein the second data segment is the next data segment in the target data download object adjacent to the first data segment. Based on the estimated network state parameters, the estimated download time for downloading the second data segment is calculated for different receive buffer sizes. The receive buffer size corresponding to the shortest estimated download time is set as the receive buffer size when downloading the second data segment. It is determined whether the second data segment is the last data segment of the target data download object. When the second data segment is not the last data segment of the target data download object, during the download of the second data segment, the corresponding data segments of the first and second data segments in the target data download object are updated to continuously control the data download process. Alternatively, when the second data segment is the last data segment of the target data download object, the data download protocol parameters are reconfigured according to the preset receive buffer size to download the new data segment of the target data download object. The technical solution of this disclosure solves the problem of the inflexible configuration of receive buffer parameters and the problem of how to control the data download process in a closed loop throughout the entire data download process. It can dynamically adjust the receive buffer during the data download process, optimize the buffer allocation and usage method when transmitting data based on the TCP protocol without changing the operating system kernel implementation, and reduce the overall data download time.

The technical solution of this disclosure solves the problem of inflexible receive buffer configuration parameters, allowing dynamic adjustment of the receive buffer during data download to reduce overall data download time.
[0104] In one optional implementation, the network state parameter estimation module 430 is specifically used for:
