Detailed Description

Embodiments of the present application are described below with reference to the accompanying drawings.

In order to control the download flow of the background resource, the embodiment of the application provides a resource downloading method, which downloads the background resource in a heartbeat flow control manner based on the size of the resource fragment and the download interval, so that the download speed of the background resource is effectively controlled, and the download efficiency of the application resource is improved.

The resource downloading method provided by the embodiment of the application can be applied to equipment with data processing capacity, such as terminal equipment or a server, the method can be independently executed through the terminal equipment, can also be independently executed through the server, can also be applied to a network scene of communication between the terminal equipment and the server, and can be executed through the cooperation between the terminal equipment and the server. The terminal equipment can be a mobile phone, a desktop computer, a portable computer and the like; the server may be understood as an application server or a Web server, and in actual deployment, the server may be an independent server or a cluster server. The resource downloading method provided by the present application is described below with a terminal as an execution subject.

Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a resource downloading method according to an embodiment of the present application. In the scenario shown in fig. 1, a terminal 101 and a server 102 are included.

The terminal 101 may be a device for a user to execute a certain network behavior, and is configured to download resource data for a resource download task corresponding to the network behavior. And the server 102 is configured to receive and respond to the fragment downloading request sent by the terminal 101.

In the resource downloading process, the terminal 101 determines the size of the resource fragment and the downloading interval according to the resource information. The resource information refers to the total data amount of the background resource downloaded by the terminal 101, the size of the resource fragment refers to the data amount of the background resource downloaded by the terminal 101 at one time, and the download interval refers to the time interval between two times of downloading the resource fragment by the terminal 101.

After determining the size of the resource fragment and the download interval, the terminal 101 sends a fragment download request to the server 102, where the fragment download request identifies the size of the resource fragment and the data size of the background resource downloaded by the terminal 101. After the time passes the duration of the downloading interval, the terminal 101 sends the fragment downloading request to the server 102 again until the background resource is downloaded.

In the scenario shown in fig. 1, if the total amount of data of the background resource downloaded by the terminal 101 is 100M, that is, the resource information is 100M, the terminal 101 determines that the size of the resource fragment is 10M according to the resource information, and the download interval is 1 s.

Based on the above, the terminal 101 sends a fragment downloading request to the server, requesting to download the background resource with a data volume of 10M. The terminal 101 starts downloading at the beginning of one second (the head of line downloading time, for example, 300ms) with 1s as the downloading interval, and waits idle (the alignment idle time, for example, 700ms) after the resource fragment downloading is completed.

The terminal 101 starts downloading the resource, and after 1s, sends the fragment downloading request to the server 102 again to request to download the background resource with the data volume of 10M. After the terminal 101 requests downloading for 10 times, the background resource with the downloaded data volume of 100M is completed.

Based on the size of the resource fragment and the downloading interval, the terminal 101 realizes downloading the background resource in a heartbeat flow control manner. By monitoring the traffic in the process of downloading the background resource by the terminal 101, the traffic graph shown in fig. 1 can be obtained, where the horizontal axis represents time and the vertical axis represents the number of packets. Since the terminal 101 determines that the size of the resource fragment is 10M, the background resource data amount requested to be downloaded by the terminal 101 each time is identified as 10M by the fragment downloading request, and the background resource data amount requested to be downloaded by the terminal 101 each time is 10M. Based on this, the flow characteristics in the process of downloading the background resource by the terminal 101 are as a curve of the heartbeat, so this manner of downloading the background resource is called as heartbeat flow control. As can be seen from the above, the terminal 101 partitions the background resource, that is, partitions the background resource with a large data size into resource partitions with a small data size, and downloads the resource partitions in a quantitative manner for multiple times, thereby implementing the downloading of the entire background resource. Because the data volume of the resource fragments downloaded each time is fixed, the bandwidth occupied by the background resource in the downloading process is reduced, and meanwhile, the downloading time of the resource fragments is controlled by combining the downloading interval, the downloading speed of the background resource is effectively controlled, and therefore, the response speed to the network behavior is improved.

Referring to fig. 2, fig. 2 is a schematic flow chart of a resource downloading method provided in the embodiment of the present application, and the resource downloading method provided in the embodiment of the present application is described below. In fig. 2, the resource downloading method includes the following steps:

s201: and determining the resource information of the background resource according to the resource downloading task.

In practical application, the terminal may determine a resource downloading task corresponding to a network behavior when executing the network behavior. The resource downloading task can be understood as a task that the network behavior terminal needs to execute the downloading resource. Aiming at one network behavior, the corresponding resource downloading task comprises at least one resource downloading task. The resources that need to be downloaded for performing each resource download task include application resources and background resources. The application resource refers to a resource directly related to the response of the terminal to the network behavior, and the background resource refers to a resource which is not directly related to the network behavior realized by the terminal.

Take the example that the terminal opens the video software. In the process of opening the video software by the terminal, resources needing to be downloaded comprise a video home page interface and special effect rendering textures. The video home page interface is a resource directly related to video software opening, namely an application resource; and the special effect rendering texture is a resource which is not directly related to the opening of the video software, namely a background resource.

The resource information of the background resource determined by the terminal refers to the total data amount of the background resource downloaded by the terminal. For example, when the terminal opens the video software, the total amount of data required by the terminal to download the special effect rendering texture is 50M. In practical application, the terminal can establish connection with the server, and the server determines the resource information of the background resource to be downloaded.

S202: and determining the size and the downloading interval of the resource fragment according to the resource information.

Generally, the data size of the background resource far exceeds the data size of the application resource. Under the condition that downloading is not limited by flow, because the data transmission bandwidth is limited, in the process of downloading resources by the terminal, the background resources occupy too much bandwidth, so that the speed of downloading the application resources by the terminal is too slow, the response time of the terminal to network behaviors is longer, and the user experience is influenced.

The application provides a feasible implementation mode, namely the size and the downloading interval of each resource fragment are determined for the background according to the resource information of the background resources, and the background resources are downloaded in a heartbeat flow control mode.

The size of the resource fragment refers to the data amount of the background resource that can be downloaded by the terminal for each transmitted fragment download request. For example, if the size of the resource fragment is 1M, the amount of background resource data that can be downloaded by the terminal at one time is 1M.

The downloading interval refers to a time interval between two times of downloading the resource fragment by the terminal. For example, if the download interval is 1s, the terminal starts downloading at the beginning of one second, the terminal starts downloading the next time after the resource fragments are downloaded for 100ms, and the terminal waits for 900 ms.

The terminal controls the data volume of the background resource downloaded each time by determining the size of the resource fragment, thereby ensuring that the background resource occupies excessive bandwidth under the condition of limited bandwidth, and correspondingly, the bandwidth occupied by the application resource is increased. Meanwhile, the terminal controls the downloading speed of the whole background resource by combining the size of the resource fragment with the downloading interval of the resource fragment, and improves the downloading speed of the application resource, so that the response speed of the terminal to network behaviors is improved, and the user experience is improved.

S203: sending a fragmented download request for the background resource based on the download interval; the shard download request identifies a size of the resource shard.

And after determining the size and the downloading interval of the resource fragment, the terminal sends a fragment downloading request to the server based on the downloading interval. The fragment downloading request carries background resource information to be downloaded, and the size of the resource fragment downloaded by the terminal each time aiming at the background resource.

The background resource information to be downloaded in the fragmentation downloading request can identify the resource content for data transmission between the terminal and the server. The size of the resource fragment can identify the size of the data volume for data transmission between the terminal and the server.

Based on the size and the downloading interval of the resource fragment, the terminal firstly sends a fragment downloading request to the server, and the terminal starts to download the resource fragment after the server responds to the fragment downloading request. And after the downloading interval time passes, the terminal sends the next fragment downloading request to the server again.

For example, the size of the resource slice is 1M, and the download interval is 1 s. When the time begins, the terminal sends a first time fragment downloading request to the server, and the fragment downloading request marks that the size of the resource fragment is 1M. The server responds to the fragmentation download request after 100ms and distributes 1M background resources to the terminal. The terminal starts downloading in 100ms, and finishes downloading the resource fragment with the data volume of 1M after 400 ms. And after waiting for 500ms, the terminal sends a second sub-fragment downloading request to the server. And after 100ms, the terminal starts the second downloading until the background resource downloading is completed.

Based on the above, the terminal identifies the size of the resource fragment in the fragment downloading request, and fixes the data size of the background resource downloaded each time. Meanwhile, the background resource is downloaded in a heartbeat flow control mode through multiple times of fragment downloading in combination with the downloading interval, and the downloading speed of the background resource is effectively controlled.

The present application provides a feasible implementation manner, where a terminal may send an http protocol message to a server through an Access Point (AP) by using a hypertext transfer protocol (http), for example, http 1.1, and request the server to distribute a background resource with a fixed data size, that is, a resource fragment, by using a range field in a header of the http message to identify a background resource to be downloaded and a size of the resource fragment to be downloaded each time.

The AP may be used as a network extension, and may be connected to other APs or a master AP to extend a wireless coverage area. The http protocol can realize data transmission between the terminal and the server, is low in cost, and can reduce resource consumption in the data transmission process.

S204: and downloading the resource fragment returned according to the fragment downloading request, wherein the resource fragment is a part of the background resource.

The terminal can establish connection with a server through an AP and a Content Delivery Network (CDN), send a fragment downloading request to the server by using the AP, respond to the fragment downloading request by the server, and distribute a resource fragment identified by the fragment downloading request to the terminal by using the CDN, so that the terminal finishes downloading the resource fragment.

The CDN can avoid bottlenecks and links which possibly influence the data transmission speed and stability on the Internet as far as possible, so that the content transmission is faster and more stable, a user can obtain required content nearby, the network congestion condition is solved, and the response speed of the user for accessing a website is improved. In practical application, the data transmission network between the terminal and the server may also adopt other manners, which is not limited herein.

Further, after downloading the resource fragment each time, the terminal may cache the resource fragment for waiting processing. In a feasible implementation manner, the terminal may perform resource merging on the resource fragments according to the downloading order after downloading all the resource fragments, so as to obtain a complete background resource. In another feasible implementation manner, the terminal may merge the downloaded resource fragments in real time according to the downloading sequence after downloading each resource fragment, and when downloading of the resource fragments is completed, the merged background resource may be obtained in time.

The resource downloading method provided in the foregoing embodiment may determine the size of the resource fragment and the downloading interval according to the resource information, and download the background resource in the resource fragment manner through the fragment downloading request, where the size of the resource fragment may identify how large the resource fragment is downloaded each time, and the downloading interval specifies a time interval for downloading adjacent resource fragments. Therefore, the downloading speed of the background resource is effectively limited from the downloading amount and the downloading interval each time, the high-efficiency flow control is realized, and the situation that the background resource downloading occupies too much bandwidth is avoided. Therefore, the resource downloading efficiency directly related to the resource downloading task is ensured, and the response speed to the network behavior is improved.

It can be understood that, since the speed of the terminal responding to the network behavior is affected by the network environment, the embodiment of the present application further provides another resource downloading method for the case of the dynamic change of the network state.

Referring to fig. 3, fig. 3 is a schematic flowchart of another resource downloading method according to an embodiment of the present disclosure. As shown in fig. 3, the method includes the following S301-S307.

After the terminal starts to execute the network behavior, resource information of the background resource is determined according to the resource downloading task corresponding to the network behavior (S301).

Since data transmission between the terminal and the server is affected by dynamically changing network conditions, the present application provides a feasible implementation manner, that is, the terminal determines the size of the resource fragment and the download interval according to the resource information and the network download parameters. The network download parameter may include a data transmission bandwidth. When the network condition is good, the terminal determines that the resource fragment is large and the downloading interval is small; and when the network condition is not good, the resource fragment determined by the terminal is small, and the downloading interval is large.

The size and the downloading interval of the resource fragments determined based on the resource information and the network downloading parameters can be adapted to the network state in the actual data transmission process, the downloading speed of the background resources is controlled more effectively, and the response speed to the network behavior is improved.

Typically, the data volume of the background resource far exceeds the data volume of the application resource. The terminal can adaptively adjust the size and the downloading interval of the resource fragment after finishing the downloading of the application resource by controlling the downloading speed of the background resource, so that the terminal can more quickly finish the downloading of the background resource.

In a feasible implementation manner, after the terminal finishes downloading the ith resource fragment, the terminal determines the size of the (i + 1) th resource fragment and the (i + 1) th download interval according to the resource information and the current network download parameter (S302). Furthermore, after sending the fragment downloading request for the ith resource fragment, the terminal waits for the (i + 1) th downloading interval to send the fragment downloading request for the (i + 1) th resource fragment, wherein the fragment downloading request for the (i + 1) th resource fragment identifies the size of the (i + 1) th resource fragment.

Based on the (i + 1) th download interval, the terminal sends an (i + 1) th fragment download request to the server for the background resource, where the fragment download request identifies the size of the (i + 1) th resource fragment (S303). After the server responds to the fragment downloading request, the (i + 1) th resource fragment is downloaded (S304). After the (i + 1) th resource fragment is downloaded, the (i + 1) th resource fragment is cached and the resource merging is waited (S305). Further, the terminal determines whether the background resources are completely downloaded (S306), and determines whether the downloading needs to be continued. If not, continuing to execute S303 and sending the (i + 2) th fragment downloading request. If yes, the terminal performs resource merging on the cached resource fragments according to the downloading sequence to obtain background resources (S307).

Based on the size and the downloading interval of the resource fragments determined in real time, the terminal sends the fragment downloading request identification to the server each time, the sizes of the resource fragments of the fragment downloading request identification are different, and the time interval of sending the fragment downloading request to the server before and after the terminal is also dynamically changed. Based on the method, the terminal can change the size and the downloading interval of the resource fragment in real time according to the network state, dynamically control the downloading speed of the background resource and ensure the downloading efficiency of the application resource.

In practical applications, there may be abnormal conditions in the network state, such as network disconnection, network signal degradation, etc., which may cause that the terminal does not complete the current resource fragment when the current download interval is over, that is, the terminal fails to download the resource fragment, so that the resource fragment cannot be used.

Aiming at the abnormal situation of downloading the resource fragments, the application provides a feasible implementation manner, if the (i + 1) th downloading interval is finished, the terminal detects that the data downloading amount of the (i + 1) th resource fragment is different from the predetermined size of the (i + 1) th resource fragment, so that the situation that the (i + 1) th resource fragment is not successfully downloaded is determined, and the terminal can send a fragment downloading request aiming at the (i + 1) th resource fragment according to the (i + 1) th downloading interval again. Or, the terminal may re-determine the size and the download interval of the (i + 1) th resource fragment according to the resource information and the current network download parameter, and send a fragment download request according to the re-determined (i + 1) th download interval, where the fragment download request identifies the re-determined size of the (i + 1) th resource fragment.

When the terminal downloads the resource fragment and meets abnormal conditions, the terminal requests the resource fragment to be downloaded again by resending the fragment downloading request. Or, the size and the downloading interval of the resource fragment are determined again, and the background resource downloading parameters are adaptively adjusted according to the network state, so that the normal downloading of the resource fragment is ensured.

Next, with reference to fig. 4, a heartbeat flow control component structure for implementing the resource downloading method shown in fig. 3 is described. In the structure shown in fig. 4, a traffic controller, a fragment downloader, a task group, a single resource download task, a download thread, a fragment data transmission channel, a file processing thread, and a file are included.

Aiming at a single resource downloading task in a task group, after a terminal determines resource information of a background resource according to the resource downloading task, the terminal firstly determines the size of an ith resource fragment and an ith downloading interval according to the resource information and network downloading parameters by using a flow controller, and then sends a fragment downloading request aiming at the background resource to a server for the ith time, wherein the fragment downloading request marks the ith downloading interval.

And after the server responds to the fragment downloading request, the terminal enters a downloading thread and downloads the ith resource fragment by using the fragment downloader. And after the ith resource fragment is downloaded, entering a file processing thread through a fragment data transmission channel, and waiting for resource combination. Meanwhile, the terminal calculates the size of the (i + 1) th resource fragment and the (i + 1) th download interval by using the flow controller. And after the ith downloading interval is finished, the terminal sends a fragment downloading request to the server for the (i + 1) th time.

And the terminal downloads all the resource fragments by circularly calling the flow controller and the fragment downloader. And after the resource fragment downloading is finished, the terminal carries out resource combination on the resource fragments according to the downloading sequence to obtain a background resource file.

In the following, with reference to the accompanying drawings, a comparison between downloading resources in a non-rate-limiting manner and downloading resources in a heartbeat flow control manner is performed, so as to describe beneficial effects of the method for implementing resource downloading in a heartbeat flow control manner provided in the embodiment of the present application.

Referring to fig. 5a and 5b, fig. 5a is a schematic flow curve diagram for implementing resource downloading in a non-rate-limiting manner according to an embodiment of the present application, and fig. 5b is a schematic flow curve diagram for implementing resource downloading in a heartbeat flow control manner according to an embodiment of the present application. The horizontal axis represents time and the vertical axis represents resource download traffic.

And the terminal opens the app to test the two modes. In the testing process, the cache in the terminal app is emptied, and in the WIFI environment, in the process from the start of clicking the app to the finish of displaying the home page picture of the app, a network data acquisition and analysis tool (such as TcpLock) can be used for capturing the flow data packet cached by the terminal as a testing parameter.

Comparing the flow graphs shown in fig. 5a and fig. 5b, in the manner shown in fig. 5a, the background resource download occupies 96.9% of the flow in the app starting process from the time when the terminal clicks the app to the time when the app home page picture display is completed. In the manner shown in fig. 5b, the terminal starts clicking the app until the first page picture display of the app is completed, and the background resource download occupies 17.7% of the flow in the app starting process.

Based on the test result, in the process of downloading the resources in a speed-limit-free mode, a large amount of bandwidth is occupied by background resource downloading; compared with a non-speed-limiting mode, the background resource flow occupation is obviously reduced and the application resource downloading speed is higher in the process of downloading the resources in the heartbeat flow control mode. Based on this, the resource downloading method provided by the embodiment of the application can effectively control the downloading speed of the background resource and improve the response speed of the terminal to the network behavior.

Based on the above described resource downloading method, the embodiment of the present application provides an application scenario suitable for the resource downloading method. Referring to fig. 6, fig. 6 is a schematic view of an application scenario of another resource downloading method provided in the embodiment of the present application. In the scenario shown in fig. 6, a terminal 601, a terminal 602, and a server 603 are included.

The user executes a certain network behavior by using the terminal 601, and at least one resource downloading task is required to be executed to complete the network behavior. As shown in fig. 6, the terminal 601 executes a network behavior a, and its corresponding resource downloading Task TaskQueue includes Task1, Task2 and Task 3; the terminal 602 executes the network behavior B, and the corresponding resource downloading tasks TaskQueue include Task1 and Task 2. When the terminal executes different network behaviors, the corresponding resource downloading tasks have differences, and the resource downloading tasks are determined according to the actually executed network behaviors.

In the scenario shown in fig. 6, a terminal 601 and a terminal 602 establish a connection with a server 603 through an AP and a CDN.

The terminal 601 determines the resource information of the corresponding background resource according to the resource downloading tasks Task1, Task2 and Task3, and further determines the size and downloading interval of the resource fragment according to the resource information. The terminal 601 sends a request for downloading a piece of request CDN1, a request CDN2 and a request CDN3 to the server 603, and downloads corresponding background resources from the CDN1, the CDN2 and the CDN3 in a heartbeat flow control manner.

Similarly, the terminal 602 determines the resource information of the corresponding background resource according to the resource downloading tasks Task1 and Task2, respectively, and further determines the size of the resource fragment and the downloading interval according to the resource information. The terminal 602 downloads the corresponding background resource from the CDN3 in a heartbeat flow control manner by sending the request for fragmented download request CDN1 and the request CDN2 to the server 603.

It should be noted that different CDNs have different resource data, and therefore, the CDN may respond to the segment download request sent by the terminal 601 according to its own setting. The terminal requests the CDN to distribute the resource fragments by generating a fragment downloading request with an identifier of the CDN. In the application scenario shown in fig. 6, the CDN1 is configured with resource data corresponding to the resource download Task1, and may respond to the request CDN1 for the fragmented download. The CDN2 is configured with resource data corresponding to the resource download Task2, and may respond to the request CDN2 for the fragmented download. The CDN3 is configured with resource data corresponding to the resource download tasks Task1, Task2, and Task3, and may respond to the fragmented download requests request CDN1, request CDN2, and request CDN 3.
