Description

Data downloading method, device, equipment, system and readable storage medium

Technical Field

The present invention relates to the field of data processing technologies, and in particular, to a data downloading method, apparatus, device, system, and readable storage medium.

Background

Electronic equipment such as a mobile phone and a computer accesses a website in the internet, establishes a connection with the website to download data provided by the website, and becomes an important way for people to acquire data in daily life.

As the internet users have increasingly large scales and limited internet resources, users usually need to access the internet through mechanisms such as network competition, and meanwhile, the website providing data downloading usually limits the speed of each connection in order to avoid that the data downloading speed of a single connection is too high to affect the data downloading of other connections, so that the website establishing multiple connections with the website to download data concurrently in the scene of single connection speed limit and network competition is an important means for improving the data downloading speed.

Currently, some application software providing data downloading services (e.g. a data downloading tool such as a network disk, or a streaming application supporting loading of streaming data, etc.) supports configuring the number of concurrent connections, which may be a default configuration provided by an application or may be manually configured by a user. The user can establish the connection of the number of concurrent connections with the site providing data downloading through the application software, so as to realize the multi-connection concurrent data downloading. However, once the number of concurrent connections is configured, the number of concurrent connections does not change in the whole data downloading process, however, different users have different network conditions for accessing the network, different sites for providing data downloading services have different actual data downloading conditions, and the actual data downloading conditions may also change dynamically in the data downloading process along with the change of the network conditions and other reasons, so that it is difficult to adapt to the difference and change of the actual data downloading conditions no matter the number of concurrent connections is set by default configuration of application software or according to user experience, and in some cases, the number of concurrent connections is set simply, which may not effectively increase the data downloading speed, but may affect the data downloading speed. For example, in a data download scenario where the network condition is good and the speed limit of a single site of a site providing data download is high, a large number of concurrent connections are set, which not only cannot effectively increase the speed of downloading data from the site, but also may cause large interaction overhead and processing resource consumption due to establishment and maintenance of a large number of connections with the site, thereby affecting the data download speed.

The general concept of the embodiment of the invention is to provide a data downloading scheme, which can determine the number of concurrent connections to be established for downloading data from a current station according to the network state of the current network and the single connection speed limit record value of the current station, continuously acquire the average downloading speed of each connection established with the current station in each observation time window in the data downloading process after establishing connection with the current station according to the number of concurrent connections and starting to download data, and when the average downloading speed of each connection established with the current station in the current observation time window meets the connection increasing condition, additionally establish a preset number of connections with the current station for downloading data, so as to adaptively configure and adjust the number of concurrent connections to implement concurrent downloading data according to the actual conditions of different stations and different networks, and acquire the optimal data downloading speed adapting to the current network and the current station, and the data downloading efficiency is improved. The method is particularly suitable for downloading scenes or loading scenes of streaming media data such as video data.

< first embodiment >

In the present embodiment, a data downloading method is provided. The data is any content that can be downloaded via a network, such as streaming media data, web page data, file data uploaded by a third party, and the like. The data downloading method may be implemented by an electronic device such as a mobile phone, a notebook computer, a desktop computer, etc., and may also be implemented by the client 1200 shown in fig. 1.

As shown in fig. 2, the data downloading method may include: steps S2100-S2300.

Step S2100, obtaining the single connection speed limit record value of the current site, and determining the number of concurrent connections to be established for downloading data from the current site according to the network state of the current network and the single connection speed limit record value of the current site.

The current site is a site that provides data that is currently to be downloaded. Generally, some sites providing downloadable data generally limit the download speed of data from a single connection in order to ensure load balance among connections when supporting multiple connections to download data. The single-connection speed limit record value of the current site is the highest data download speed value which can be supported by a single connection in the current site.

In this embodiment, the saved single connection speed limit record value of the current site may be read locally, or a request may be made to other data downloading devices (for example, a server for recording the single connection speed limit record values of the respective sites) to obtain the single connection speed limit record value of the current site.

It should be understood that "locally" in the descriptions of "locally save", "save in local", and the like, refers to relevant storage that is locally available for saving data in the device implementing the embodiment, and includes a local cache, a local memory, or a local file for persistently saving data, and the like, and when implemented specifically, corresponding data may be saved through the local cache, the local memory, or the local file according to a specific application scenario or an application requirement. The number of concurrent connections is the number of connections concurrently established when downloading data from the current site. After the single connection speed limit record value of the current site is obtained, the number of concurrent connections required to be established for downloading data from the current site can be determined according to the network state of the current network and the single connection speed limit record value of the current site, the situation of the current site and the network state of the current network can be automatically adapted, the initial concurrent connections are set when the data are downloaded from the current site, the initial speed of downloading the data from the current site is effectively guaranteed, and the number of concurrent connections can be adjusted by rapidly adapting to the change of the subsequent network state in combination with the subsequent steps.

In one example, the network status of the current network includes at least one of a network type, a network signal strength, a recent network speed test value, and a historical network speed record value of the current network. The network type of the current network is the network type of the current network, and can include GSM/WCDMA/TD-SCDMA/TD-LTE/LTE-FDD/WIFI and the like. The network signal strength of the current network can be detected in real time or requested to be provided by the detected and acquired equipment by calling or triggering the corresponding test equipment. The latest network speed measurement value of the current network is a data download speed value obtained by testing the current network in the latest statistical time period, and can call or trigger corresponding testing equipment to perform real-time detection or request equipment which has detected and obtained a value to provide. The historical wire speed record value is a data download speed value of the current network recorded in the historical statistic time period, and can be read from a log of the recorded historical data stored locally or provided by a device requesting to record the historical data.

In this example, the step of determining the number of concurrent connections to be established for downloading data from the current site according to the current network state and the single connection speed limit record value of the current site may include: steps S2110-S2120.

Step S2110, acquiring the network speed of the current network according to the network state of the current network.

By acquiring the network speed of the current network, the performance of downloading data of the current network at the current time point can be accurately determined.

In this example, step S2110 may include steps S2111-S2113.

Step S2111, when the network state includes the latest network speed test value, the latest network speed test value is taken as the network speed of the current network.

The latest network speed test value reflects the data downloading speed of the current network in the latest statistical time period away from the current time point, can reflect the truest data downloading performance of the current network at the current time point, and can be combined with the subsequent steps to obtain the concurrent connection number which is most suitable for the current network and the current station situation by taking the latest network speed test value as the network speed of the current network.

Step S2112, when the network state does not include the latest network speed test value but includes the network type and the network signal strength, determining the network speed of the current network according to the network type and the network signal strength.

When the network state does not include the latest network speed test value, the network speed of the current network can be determined through the network type and the network signal strength reflecting the data downloading performance of the current network, and the concurrent connection number which is most suitable for the current network and the current site condition is obtained by combining the subsequent steps. Generally, under different network systems, the optimal data downloading speed of a corresponding network under ideal signal intensity can be determined through a large amount of test data, the corresponding optimal data downloading speed can be determined through the network systems, a speed weight is set according to the ideal signal intensity corresponding to the optimal data downloading speed and the network signal intensity of the current network, and the speed weight and the optimal data downloading speed are multiplied to obtain a numerical value which can be used as the network speed of the current network.

It should be understood that, when the network state only includes the network type or the network signal strength, the optimal data downloading speed may also be determined according to the network type, or a value obtained by multiplying the optimal data downloading speed by a preset weight after selecting the optimal data downloading speed from the historical test data according to the network signal strength is used as the network speed of the current network.

And step S2113, when the network state only comprises the historical network speed record value, taking the historical network speed record value as the network speed of the current network.

The historical network speed record value reflects the data downloading speed of the current network obtained in the historical statistical time period, although the data downloading speed may not be the latest data downloading speed of the current network, the data downloading performance of the current network is reflected to a certain extent, when other information reflecting the network state cannot be obtained due to the network system, the equipment capacity and the like, the historical network speed record value is used as the network speed of the current network, and the concurrent connection number which is most suitable for the conditions of the current network and the current site can be obtained by combining with the subsequent steps.

After acquiring the network speed of the current network in step S2110, the method proceeds to:

and S2120, acquiring the number of concurrent connections according to the network speed of the current network and the single-connection speed limit record value.

Suppose that the network speed of the current network is V_netThe single-connection speed limit record value of the current station is V_limitCorresponding number of concurrent connections N_linkComprises the following steps:

in some cases, due to reasons such as communication abnormality and limited processing resources, a single-connection speed limit record value of a current site may not be obtained in time, and for this reason, the data downloading method provided in another example in this embodiment may further include:

and when the single-connection speed limit record value of the current site cannot be acquired, taking the preset default number of concurrent connections as the number of concurrent connections.

The default number of concurrent connections can be preset according to engineering experience values or experimental simulation data for a specific data download scene.

When the single-connection speed-limit record value of the current site cannot be acquired, the preset default concurrent connection number is used as the concurrent connection number, so that the data downloading method provided by the embodiment can be normally started, the concurrent connection number is configured in a self-adaptive manner according to the actual condition of the current network in combination with the subsequent steps, the optimal data downloading speed adaptive to the current network and the current site is acquired, and the data downloading efficiency is improved.

After determining the number of concurrent connections in step S2100, the method proceeds to:

step S2200 is that after the connection with the current station is established according to the number of concurrent connections and the data starts to be downloaded, the average download speed of each connection established with the current station in each observation time window is continuously obtained during the data download process.

The observation time window is a period for observing the average download speed for acquiring the connection established with the station, the period is a period lasting before the current observation time point, specifically, the period duration may be set according to a specific application scenario or application requirement, for example, set to 3 seconds, and then each corresponding observation time duration is a period within 3 seconds before the current observation time point.

The average download speed of each connection established with the current site is the average speed of downloading data from the current site based on the connection in the corresponding observation time window, and can reflect the data download performance of the connection.

By continuously acquiring the average downloading speed of each connection established with the current site in each observation time window in the data downloading process, the change of the data downloading performance of each connection for downloading data from the current site based on the current network can be continuously monitored, so that the connection with the current site is increased to adapt to the change of the data downloading performance in combination with the subsequent steps, the concurrent data downloading is implemented by adaptively configuring and adjusting the number of concurrent connections according to the actual conditions of different networks and different sites, the optimal data downloading speed adapted to the current network and the current site is acquired, and the data downloading efficiency is improved.

In this embodiment, a test device or a test module that implements the electronic device setting in this embodiment may be invoked, and an average download speed of each connection established with the current site in each observation time window is obtained by monitoring the data volume of the transceiving data packets of each connection established with the current site, where no limitation is made herein.

In practical application, in order to ensure that the obtained average downloading speed of each connection established with the current station is effective, the average downloading speed of each connection established with the current station in each observation time window can be observed and obtained based on the observation time window after the connection is established with the current station according to the number of concurrent connections and waiting for the preset time, so that the situation that the average downloading speed is observed and obtained when the connection established with the current station does not actually start downloading data is avoided, and the real and effective average downloading speed cannot be obtained. The preset time may be set to a specific duration according to an engineering experience value, and is not specifically limited herein.

Step S2300, when the average downloading speed of each connection established with the current site in the current observation time window meets the connection increasing condition, additionally establishing a preset number of connections with the current site for downloading data.

The connection increasing condition is a condition for judging whether to newly establish a connection with the current site in the data downloading process according to the average downloading speed of each connection established with the current site. When the average download speed of each connection established with the current site in the current observation time window meets the connection increase condition, it means that the performance of downloading data concurrently based on multiple connections established between the current network and the current site in the current observation time window cannot adapt to the actual conditions of the current network and the current site, and the connection established with the current site needs to be increased to realize adaptation to the actual conditions of the current network and the current site and obtain the current optimal data download speed.

The preset data for establishing the connection can be set according to engineering experience values or experimental simulation data according to actual requirements, and is not limited herein.

In one example, the connection addition condition may include that a speed similarity condition is satisfied between average download speeds of each connection established with the current station, an average download speed of all connections established with the current station is not less than a value obtained by subtracting a difference threshold from a highest speed record value of a single connection of the current station, and a suspected speed limit record value of the single connection of the current station is not locally recorded, or, when a suspected speed limit record value of the single connection is locally recorded, the average download speed is not less than a value obtained by subtracting the similarity threshold from the suspected speed limit record value of the single connection.

The speed proximity condition is a condition for judging whether the average download speed of each connection established with the current station belongs to a proximity speed. The average downloading speed of each connection established with the current site is consistent with the speed approximation condition, which means that the average downloading speed of each connection established with the current site is approximate, and the data downloading performance of each connection is balanced.

The speed similarity condition may specifically be that a ratio between a maximum speed value and a minimum speed value selected from the average download speeds of each connection established with the current station is not less than a similarity ratio. The maximum speed value and the minimum speed value may be selected after sorting the average download speed of each connection established with the current station, and may also be selected after sorting to remove the maximum value and the minimum value and avoid distortion. The ratio of the minimum speed value and the maximum speed value selected from the average downloading speeds of each connection established with the current station is not smaller than the similar ratio, which means that the ratio is similar to the maximum speed value and the minimum speed value of the average downloading speed of each connection established with the current station, and further means that the ratio is similar to the average downloading speed of each connection established with the current station. The approximation ratio may be set to a value close to 1, for example, to 0.9, meaning that the ratio of the minimum speed value and the maximum speed value is not less than 0.9, and the values are close to each other.

The download speed average is the average of the average download speeds of all connections established with the current site. The average download speed of all connections established with the current site is not less than the value obtained by subtracting the difference threshold from the highest speed record value of the single connection of the current site, which means that the average download speed of all connections established with the current site is not significantly lower or higher than the highest speed record value of the single connection of the current site, i.e. the average download speed of all connections established with the current site is similar to the highest speed record value of the single connection of the current site, and the average download speed of each connection established with the current site is similar to the average download speed of each connection established with the current site, i.e. the average download speed of each connection established with the current site is similar to the highest speed record value of the single connection of the current site, and each connection established with the current site is already close to the upper download speed limit. The difference threshold may be a threshold for determining whether the two values are close to each other according to a difference between the two values, and a smaller value may be set according to engineering experience data, which is not specifically limited herein.

The single-connection suspected speed-limit recorded value of the current site is a suspected highest data download speed value that can be supported by the current site for a single connection, and the single-connection suspected speed-limit recorded value can be updated to the single-connection speed-limit recorded value of the current site after multiple observations and confirmations, which will be described later in this embodiment.

The suspected speed limit record value of the single connection of the current site is not recorded locally, which means that the current site does not acquire the suspected speed limit record value of the single connection before. When a single-connection suspected speed-limit record value is locally recorded, the average downloading speed is not less than a value obtained by subtracting a similar threshold value from the single-connection suspected speed-limit record value, which means that the average downloading speed is similar to the single-connection suspected speed-limit record value or higher than the single-connection suspected speed-limit record value, but is similar to the average downloading speed of each connection established with the current site, that is, the average downloading speed of each connection established with the current site is similar to the single-connection suspected speed-limit record value of the current site, and each connection established with the current site is already close to the upper limit of the data downloading speed which may be set by the current site. The similar threshold may be a threshold for judging whether the two values are close to each other according to a difference between the two values, and a smaller value may be set according to engineering experience data, which is not specifically limited herein.

In this example, by setting the connection increase condition as described above, when the average download speed of each connection established with the current station is similar to, neither significantly lower than or higher than the highest speed record value of the single connection of the current station, or on the basis of the average download speed of each connection established with the current station, both of the connections are further close to or higher than the suspected speed limit record value of the single connection of the current station, it is correspondingly determined that each connection established with the current station is close to the limit of the data download performance of the connection, the connection establishment with the current station can be correspondingly triggered to effectively increase the data download speed, and the number of concurrent connections is adjusted to implement data concurrent download for changes in the actual data download performance based on the current network and the concurrent data download of the current station.

In a more specific example, the single-connection suspected speed limit recorded value may be recorded according to the following step S2301, which includes:

and when the average downloading speed of each connection established with the current site in the current observation time window meets the connection increasing condition and the single-connection suspected speed-limiting record value is not recorded locally, recording the average downloading speed as the single-connection suspected speed-limiting record value and storing the single-connection suspected speed-limiting record value locally.

The average download speed of each connection established with the current site in the current observation time window meets the connection increasing condition in the above example, which means that the corresponding download speed average value also meets the connection increasing condition in the above example, so that the download speed average value can represent the upper limit of the data download performance of each connection established with the current site in the current observation time window and under the current network, and when the single-connection suspected speed-limit recorded value is not recorded locally, the download speed average value is recorded as the single-connection suspected speed-limit recorded value, so that the follow-up judgment of whether the connection increasing condition is met or not can be more accurate according to the single-connection suspected speed-limit recorded value.

In another more specific example, the single-connection suspected speed limit record value may be updated according to the following step S2302, which includes:

and when the average downloading speed of each connection established with the current site in the current observation time window meets the connection increasing condition and the average downloading speed is greater than the numerical value obtained by adding the similar threshold to the single-connection suspected speed-limiting record value, updating the single-connection suspected speed-limiting record value into the average downloading speed.

The average download speed of each connection established with the current site in the current observation time window conforms to the connection increasing condition in the above example, meaning that the corresponding download speed mean also conforms to the connection increasing condition in the above example, then the download speed mean can represent the data download performance upper limit of each connection established with the current site in the current observation time window under the current network, and the download speed mean conforming to the connection increasing condition in the above example is greater than the value obtained by adding the single-connection suspected speed-limit record value to the similar threshold, meaning that the download speed mean is significantly higher than the recorded single-connection suspected speed-limit record value, the currently recorded single-connection suspected speed-limit record value is not accurate enough, and the single-connection suspected speed-limit record value is updated to the download speed mean, so that the subsequent single-connection suspected speed-limit record value can be based on the single-connection suspected speed-limit record value, whether the connection increasing condition is met or not is judged more accurately.

In still another more specific example, there may be further provided the step S2303 of locally recording the single connection speed limit record value, including:

and when the single-connection speed limit record value is acquired from other data downloading equipment, reporting the speed limit record comprising the site information of the current site and the single-connection suspected speed limit record value, and sending the speed limit record to the data downloading equipment providing the single-connection speed limit record value.

In the current observation time window and the preset number of observation time windows before the current observation time window, the average download speed of each connection established with the current site meets the connection increasing condition in the above example, which means that the download speed mean values in the corresponding observation time windows are confirmed for multiple times to meet the requirements of the connection increasing condition and are close to the upper limit of the data download performance of the single connection in the corresponding observation time window, and the difference value between the download speed mean value in the observation time windows and the single-connection suspected speed-limit record value is not more than the close threshold, which means that the recorded single-connection suspected speed-limit record value is confirmed for multiple times to be close to the download performance of the single connection in the corresponding observation time window, that the recorded single-connection suspected speed-limit record value is confirmed for multiple times to be close to the upper limit of the data download performance of the single connection in the current supportable single site, then, the single-connection suspected speed-limit record value can be confirmed to accurately represent the current site in the The upper limit of the connected data downloading speed is set as the single-connection suspected speed limit record value of the current site and stored locally, and the data downloading method provided by the embodiment can be implemented by using the single-connection speed limit record value which is newly recorded locally when data downloading is implemented at the current site next time, so that the connection concurrency number is determined to establish concurrent connection with the current site, concurrent data downloading is implemented, and the data downloading performance is further improved.

As described above, in this embodiment, the single-connection speed-limit record value of the current site may also request other data downloading devices (for example, a server recorded with the single-connection speed-limit record value of the current site) to obtain the speed-limit record value, and then, when it is determined that the single-connection suspected speed-limit record value can accurately represent the upper limit of the data downloading speed of the current supportable single connection at the current site, the speed-limit record including the site information of the current site and the single-connection suspected speed-limit record value is reported and sent to the data downloading device providing the single-connection speed-limit record value, and the data downloading device may be triggered to update the recorded connection speed-limit record value of the current site, so as to ensure that the newly recorded single-connection speed-limit record value can be obtained when data downloading is performed at the current site next time, and implement the data downloading method provided in this embodiment, and determining the connection concurrency number to establish the concurrent connection with the current site, implementing concurrent data downloading, and further improving the data downloading performance.

As shown in fig. 3, based on the connection addition condition set in the above example, the process of determining whether to add the established connection to the current station according to the average download speed of each connection established with the current station in the current observation time window may include: steps S201-S213.

Step S201, obtaining an average download speed of each connection established with the current station in the current observation time window.

Step S202, judging whether the average download speed of each connection established with the current station accords with the speed similar condition, if so, entering step S203, otherwise, returning to step S201, and continuously observing and obtaining the average download speed of each connection established with the current station in the next current observation time window.

Step S203, judging whether the average value of the download speed calculated according to the average download speed of each connection established with the current site is not less than the value obtained by subtracting the difference threshold from the highest speed record value of the single connection of the current site, if so, entering step S204, otherwise, returning to step S201, and continuously observing and obtaining the average download speed of each connection established with the current site in the next current observation time window.

And step S204, judging whether the single-connection suspected speed-limiting record value of the current site is recorded locally, if the single-connection suspected speed-limiting record value of the current site is not recorded, entering step S205, otherwise, entering step S207.

And step S205, recording the average downloading speed as a single-connection suspected speed limit record value and storing the single-connection suspected speed limit record value locally.

Step S206, a preset number of connections with the current station are added to download data, and then the process returns to step S201 to continue to observe and obtain the average download speed of each connection established with the current station in the next current observation time window.

And step S207, judging whether the average downloading speed is not less than a numerical value obtained by subtracting a similar threshold value from a single-connection suspected speed limit record value recorded locally, if so, entering step S208, otherwise, returning to step S201, and continuously observing and obtaining the average downloading speed of each connection established with the current site in the next current observation time window.

Step S208, judging whether the average value of the download speed is larger than a numerical value obtained by adding a similar threshold to the single-connection suspected speed-limiting record value of the local record, if so, entering step S209, otherwise, indicating that the average value of the download speed is similar to the single-connection suspected speed-limiting record value of the local record, and entering step S206 and step S210 respectively.

In step S209, the single-connection suspected speed limit record value is updated to the average download speed, and the process goes to step S206.

Step S210, determining whether the average download speed is close to the single-connection suspected speed limit record value of the local record in the current time observation window and the preset number of time observation windows before, if yes, going to step S211, otherwise, ending the process.

And step S211, setting the single-connection suspected speed limit record value as the single-connection speed limit record value of the current site and storing the single-connection suspected speed limit record value in the local.

Step S212, judging whether the previous single-connection speed limit record value is acquired from other data downloading equipment, if so, entering step S213, otherwise, ending the process.

And step S213, reporting the speed limit record comprising the site information of the current site and the single-connection suspected speed limit record value, sending the speed limit record to the data downloading equipment providing the single-connection speed limit record value, and ending the process.

In the example of the connection addition condition set according to the above example, there may be further provided a step of recording, managing a single-connection maximum speed recording value, including: steps S2304-S2306.

Step S2304, when the maximum average download speed in the average download speeds of each connection established with the current site in the current observation time window is greater than the locally stored maximum speed record value of the single connection, updating the maximum speed record value of the single connection to the maximum average download speed.

And step S2305, when the single-connection speed-limit recorded value is locally stored and the difference value of the updated single-connection highest speed recorded value higher than the single-connection speed-limit recorded value is greater than the abnormal threshold value, the locally stored single-connection speed-limit recorded value is cleared.

The abnormal threshold is a threshold used for judging whether the updated highest speed record value of the single connection is abnormally higher than the speed-limiting record value of the single connection, and can be set according to engineering experience or experimental simulation data.

The difference value that the updated single-connection maximum speed record value is higher than the single-connection speed limit record value is larger than the abnormal threshold value, which means that the single-connection maximum speed record value is abnormally higher than the single-connection speed limit record value, and the currently recorded single-connection speed limit record value cannot accurately reflect the upper limit of the single-connection data downloading speed supported by the current site, so that the locally stored single-connection speed limit record value is cleared, the influence of the locally stored single-connection speed limit record value on next data downloading can be avoided, and the data downloading efficiency is reduced.

Step S2306, when the single connection speed limit record value is obtained from other data downloading equipment, and the difference value of the updated single connection highest speed record value higher than the single connection speed limit record value is larger than the abnormal threshold value, the speed limit record error correction information at least including the indication information of the current site is sent to the data downloading equipment providing the single connection speed limit record value, and is used for correcting the single connection speed limit record value provided by the data downloading equipment.

The difference value that the updated single-connection maximum speed record value is higher than the single-connection speed limit record value is larger than the abnormal threshold value, which means that the single-connection maximum speed record value is abnormally higher than the single-connection speed limit record value, and means that the single-connection speed limit record value obtained from other data downloading equipment can not accurately reflect the upper limit of the single-connection data downloading speed supported by the current site, therefore, the data downloading equipment providing the single-connection speed limit record value can be triggered through sending the speed limit record error correction information, the provided single-connection speed limit record value of the current site is correspondingly corrected, the influence of the provided single-connection speed limit record value on next data downloading is avoided, and the data downloading efficiency is reduced.

As shown in fig. 4, the process of managing the single connection maximum speed record value in this example based on the connection addition condition set in the above example may include: steps S221-S227.

Step S221, selecting the largest average download speed from the average download speeds of each connection established with the current station in the current observation time window.

Step S222, determining whether the maximum average download speed is greater than the maximum speed record value of the single connection already stored locally, if yes, going to step S223, if no, going back to step S221, and selecting the maximum average download speed from the average download speeds of each connection established with the current station in the next current observation time window to implement the present process.

Step S223, the single-connection highest speed record value of the current site is updated and set to the maximum average download speed.

And step S224, judging whether the updated highest speed record value of the single connection is higher than the difference value of the speed limit record value of the single connection and is larger than an abnormal threshold value, if so, entering step S225, otherwise, returning to step S221, and selecting the largest average downloading speed from the average downloading speeds of each connection established with the current site in the next current observation time window to implement the process.

Step S225, judging whether the single connection speed limit record value is obtained from local, if yes, entering step S226, otherwise, the single connection speed limit record value is obtained from other data downloading equipment, and entering step S227.

Step S226, the locally stored speed limit record of the single connection is cleared, and then the process returns to step S221, where the largest average download speed is selected from the average download speeds of each connection established with the current station in the next current observation time window to implement the process.

Step S227, sending the error correction information of the speed limit record at least including the indication information of the current station to the data downloading device providing the single-connection speed limit record value, and then returning to step S221, and selecting the largest average downloading speed from the average downloading speeds of each connection established with the current station in the next current observation time window to implement the present process.

In the process of downloading data from the current site according to the data downloading method provided by the present embodiment, any one connection established with the current site may end due to completion of data downloading or due to an abnormal connection. For this case, in one example, the provided data downloading method further includes:

when any connection established with the current site finishes data downloading or abnormally finishes, and the number of the remaining connections established with the current site is determined to be less than the preset default number of concurrent connections, the connection is additionally established with the current site, so that the number of the connections established with the current site is in accordance with the default number of concurrent connections.

The default concurrent connection number is a preset concurrent connection number supported by the default of the current site, and may be set for a specific scene according to an engineering experience value or experimental simulation data, or a concurrent connection number determined when a connection is initially established with the current site is used as the default concurrent connection number.
