[0046] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

It should also be understood that the term "and / or" used in one or more embodiments of the present application refers to and includes any or all possible combinations of one or more associated listed items.

[0048] It should be understood that, although the terms first, second, etc. may be used to describe various information in one or more embodiments of the present application, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0049] First, the terms involved in one or more embodiments of the present invention are explained.

[0050] CDN: (Content Delivery Network), which is a content distribution network. Its basic idea is to avoid bottlenecks and links on the Internet that may affect the speed and stability of data transmission as much as possible, so as to make content transmission faster and more stable.

[0051] HTTP: (Hypertext Transfer Protocol), the Hypertext Transfer Protocol, is a simple request-response protocol that usually runs on top of TCP. It specifies what kind of messages a client may send to a server and what kind of response it may get.

[0052] Range: Used to anchor a portion of a file.

[0053] In the present application, a data packet downloading method is provided. The present application also relates to a data packet downloading device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0054] Figure 1 A flowchart of a method for downloading a data packet according to an embodiment of the present application is shown, which specifically includes the following steps:

[0055] Step S102: Divide the local cache space of the target device to obtain a pre-download window space, wherein the target device is used to download the target data packet;

[0056] Step S104: querying the data volume parameter of the target data packet according to the download address received by the target device, and dividing the target data packet according to the data volume parameter to obtain a plurality of data segments to be downloaded;

[0057] Step S106: downloading the data segment to be downloaded based on the pre-download window space;

[0058] Step S108: receiving a download request through the download program of the target device, and in response to the download request, the download program reads the to-be-downloaded data segment in the pre-download window space.

[0059] In actual usage scenarios, the size of data packets is getting larger and larger. For example, the size of game installation packages is generally above 40G, and users have higher and higher requirements for the download speed of data packets. However, even if gigabit broadband is installed, the ideal full-speed download speed cannot be achieved. The reason for this problem is that CDN has no cache, and CDN cannot achieve cache at every edge node.

[0060] Among the existing data packet download solutions, most use the HTTP protocol for data download and combine it with multiple streams for downloading. That is, the client initiates multiple HTTP sessions to the CDN node. Each HTTP session downloads a different Range, which are then merged after the download is completed. In this way, different parts of the same file can be downloaded at the same time, realizing segmented downloading to achieve the purpose of speeding up. However, this segmented download method still cannot achieve the ideal speed of full-speed download.

[0061] Based on this, the pre-download window space is obtained by dividing the local cache of the target device, where the target device is the client device from which the user downloads the target data packet. Then, the size of the data packet, i.e., the data volume parameter, is queried through the download position of the target data packet, and then the target data packet is divided to obtain multiple data segments to be downloaded, so as to achieve the purpose of segmented downloading.

[0062] Afterwards, the data segment to be downloaded is downloaded through the pre-download window space. It should be noted that the download process of the data segment to be downloaded in the pre-download window space can be performed in the background, which does not affect the user's other operations on the target device. When the user downloads the target data packet through the download program, the user triggers the download action through the preset UI control. After generating the corresponding download request, the download program responds to the download request, grabs the data that has been downloaded in the pre-download window space, and realizes the high-speed download of the target data packet. It should be noted that the download program can be a partial management system program, an upgrade program or an accelerator of the software to be upgraded, etc. The specific download program type is determined by the actual use scenario and is not limited by the embodiment itself.

[0063] Furthermore, the process of dividing the local cache space of the target device to obtain the pre-download window space is specifically implemented as follows in this embodiment:

[0064] Determine the local cache space capacity of the local cache space; calculate the window space capacity of the pre-download window space by a preset proportionality coefficient according to the local cache space capacity; divide the local cache space based on the window space capacity to obtain the pre-download window space.

[0065] Among them, the pre-download window space is divided out from the local cache space to ensure the normal operation of the target device. Therefore, the capacity of the divided pre-download window space should not be too large. According to actual measurements, the capacity of the pre-download window space is 5%-20% of the local cache space, which will not affect the normal use of the target device.

[0066] Based on this, the capacity of the local cache space, i.e., the local cache space capacity, is determined, and then the capacity of the divided pre-download window space, i.e., the window space capacity, is calculated according to a preset ratio coefficient. In actual usage scenarios, the ratio coefficient is generally set to 5% to minimize the impact on the normal use of the target device. The local cache space is divided according to the determined window space capacity to obtain the pre-download window space.

[0067] Furthermore, in addition to setting a fixed proportional coefficient to divide the local cache space to obtain the pre-download window space, the proportional coefficient can also be associated with the utilization rate of the local cache space of the target device. In this embodiment, the specific implementation method is as follows:

[0068] Query the historical space utilization of the local cache space; select a target proportional coefficient in a preset proportional coefficient interval according to the historical space utilization; and calculate the window space capacity through the target proportional coefficient according to the local cache space capacity.

[0069] Among them, by calling the log of the target device, the historical space utilization of the local cache space is determined, that is, the average utilization of the local cache space during the operation of the target device; the target proportional coefficient is selected according to the historical space utilization. Specifically, when the utilization rate of the local cache space is not high, it proves that there is long-term unused space in the local cache space. In this case, the selected target proportional coefficient will be larger to obtain a larger capacity pre-download window space. Conversely, when the utilization rate of the local cache space is high, it proves that the space in the local cache space has been occupied for a long time. In this case, the selected target proportional coefficient should be smaller to avoid the division of the pre-download window space from affecting the normal use of the target device.

[0070] Furthermore, in some scenarios, the historical space utilization rate of the local cache space is high, while during the current download of the target data packet through the pre-download window space, the space utilization rate of the local cache space is not high. In this case, the capacity of the pre-download window space can be increased. In this embodiment, the specific implementation method is as follows:

[0071] The space utilization rate of the local cache space is collected during the period when the download program responds to the download request; the local cache space is divided according to the space utilization rate, and the window space capacity of the pre-download window space is adjusted based on the division result.

[0072] Among them, since the space utilization rate of the local cache space is not high during the download of the target data packet through the pre-download window space, the capacity increase of the pre-download window space will not affect the normal operation of the target device.

[0073] Based on this, the space utilization rate of the local cache space is collected during the download program's response to the download request, and the local cache space is divided secondary according to the collected space utilization rate to increase the space capacity of the pre-download window space, thereby further improving the download speed of the target data packet without affecting the normal operation of the target device.

[0074] Furthermore, in response to the download request, the download program reads the data segment to be downloaded in the pre-download window space. In this embodiment, the specific implementation is as follows:

[0075] According to the download node included in the download request, a target data segment to be downloaded among the multiple data segments to be downloaded is determined; the storage location of the target data segment to be downloaded in the pre-download window space is queried; according to the storage location, the download program reads the target data segment to be downloaded in the pre-download window space.

[0076] Among them, in the prior art, after the user starts the download program, the download program downloads the target data packet according to the network, and the network quality and bandwidth conditions will restrict the download speed. Through the pre-download window space, the target data packet is downloaded continuously, and the data segment to be downloaded of the target data packet is cached until the download program needs to execute the download task, and the corresponding download target, that is, the target data segment to be downloaded, is read from the pre-download window space. The network quality and bandwidth conditions have no effect on the download speed, thereby improving the download speed.

[0077] Based on this, in actual usage scenarios, the target device downloads the data segment to be downloaded through the pre-download window space according to the HTTP request initiated by the client. After starting the download program of the target device, when the client's Range request reaches the download program, the target data segment to be downloaded is determined, and the download program reads the target data segment to be downloaded from the corresponding storage location of the pre-download window space.

[0078] Furthermore, the process of downloading the data segment to be downloaded based on the pre-download window space is specifically implemented as follows in this embodiment:

[0079] Determine a predicted download node according to the download node included in the download request; determine a predicted data segment to be downloaded among the multiple data segments to be downloaded according to the predicted download node; and download the predicted data segment to be downloaded based on the pre-download window space.

[0080] Among them, since the target data packet is downloaded in segments, the data segment to be downloaded currently can be determined according to the download node contained in the download request, and then the data segment to be downloaded that needs to be downloaded later is predicted, that is, the data segment to be downloaded including the predicted download node, and the predicted data segment to be downloaded is downloaded through the pre-download window space. When the download program subsequently reads the data segment to be downloaded, it can directly read it without waiting, thereby improving the download efficiency.

[0081] Specifically, in the actual usage scenario, assuming that the target data packet A (x 0 , x 4 ) is divided into a 1 (x 0 ,x 1 )、a 2 (x 1 ,x 2 )、a 3 (x 2 ,x 3 )、a 4 (x 3 ,x 4 ) These four data segments to be downloaded, among which x 0 -x 4 For downloading nodes. In the downloading program, the download data segment a 1 (x 0 ,x 1 ) is in the process of downloading, at this time, according to the download node x contained in the download request 0 , determine the current download is from the download node x 0 Start by predicting the subsequent download nodes, that is, predicting the download node to be x 1 , then it can be predicted that the data segment a to be downloaded will be downloaded later 2 (x 1 ,x 2 ), the pre-download window space can be used to download data segment a 2 (x 1 ,x 2 ) to download.

[0082] Furthermore, during the process of downloading the data segments to be downloaded in the pre-download window, the data segments to be downloaded may be downloaded in segments to increase the download speed. In this embodiment, the specific implementation is as follows:

[0083] The data segments to be downloaded are divided to obtain a plurality of data fields to be downloaded; and the plurality of data fields to be downloaded are asynchronously downloaded based on the pre-download window space.

[0084] Among them, the pre-download window space in the above example is used to treat the download data segment a 2 (x1 ,x 2 ) is used to download data. At this time, the data segment to be downloaded is divided into a 21 (x 1 ,x 1.2 ), a 22 (x 1.2 ,x 1.4 ), a 23 (x 1.4 ,x 1.6 )a 24 (x 1.6 ,x 1.8 ), a 25 (x 1.8 ,x 2 ) These five data fields to be downloaded are then downloaded asynchronously to increase the download speed.
