Description
Technical Field
The present disclosure relates to the field of internet technologies, and in particular, to a method and apparatus for downloading resources, a computing device, and a computer readable storage medium.
Background
The conventional resource downloading method in the prior art generally comprises HTTP downloading and BT downloading, wherein the downloading mode of HTTP downloading is downloading sequentially according to a file sequence, along with the development of the game field, pre-update downloading can be preset before the game needs to be updated greatly, a client firstly inquires whether a pre-update resource package exists on a server and downloads, for most players, normal games can be performed after the pre-update resource package is downloaded, and then other resource packages except the pre-update package are downloaded. However, the HTTP download method still requires downloading resources from the central server, so there is a bandwidth limitation, and there is a limitation on the number of clients downloaded at the same time, resulting in a slow download speed.
Another downloading method in the prior art is BT downloading, and the clients download and upload resources at the same time, and the clients mutually upload resources. Early downloads required a central server for coordinating the download relationships of the individual users. The present development to the BT2.0 stage is a distributed hash algorithm, and the resource of the client can be found to realize downloading without a central server. However, BT download has a major drawback that the distribution of resources is very uneven, and for resources with more sources, the download speed is fast, but for scarce resources, the download speed is slow due to fewer uploadable clients, which severely limits the efficiency and speed of BT download.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is, however, susceptible of embodiment in many other ways than those herein described and similar generalizations can be made by those skilled in the art without departing from the spirit of the application and the application is therefore not limited to the specific embodiments disclosed below.
The terminology used in the one or more embodiments of the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the one or more embodiments of the specification. As used in this specification, one or more embodiments and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used in one or more embodiments of the present specification refers to and encompasses any or all possible combinations of one or more of the associated listed items.
It should be understood that, although the terms first, second, etc. may be used in one or more embodiments of this specification to describe various information, these information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, a first may also be referred to as a second, and similarly, a second may also be referred to as a first, without departing from the scope of one or more embodiments of the present description. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.
First, terms related to one or more embodiments of the present invention will be explained.
Target file to be downloaded: and the client downloads all resources corresponding to the file in the current downloading task.
Resource sequence: and the sorting queue of the plurality of resource packages to be downloaded forming the target file to be downloaded.
And (5) waiting for downloading the resource package: dividing a target file to be downloaded into a plurality of resource packages according to the seed file;
the target waits for the resource package to be downloaded: refers to a resource package that the client is about to download.
Scarce resources: in BT download, there are fewer resource packages with fewer resource distributions and more requested downloads.
Scarcity degree: and under the P2P file transmission protocol, each client calculates the scarcity of each resource to be downloaded according to the request number and the resource distribution condition of each resource package to be downloaded in the current period.
Threshold of scarcity: and the client side carries out repeated feedback adjustment according to the experience data to obtain a threshold value for judging the resource scarcity.
Hypertext transfer protocol HTTP download: file transfer between client-server based on TCP/IP protocol.
Bit stream BT download: based on the downloading mode of the bit stream BitTorrent protocol, the bit stream BitTorrent protocol is a P2P file transfer protocol which is constructed on top of the TCP/IP protocol and is in an application layer of the TCP/IP structure, and the BitTorrent protocol itself also comprises a plurality of specific content protocols and expansion protocols and is in continuous expansion. According to the BitTorrent protocol, a file issued by a file issuer generates a seed file for providing a file, wherein the seed file is essentially a text file and comprises two parts of trace (Tracker) information and file information, the trace information is mainly an address of a trace server required to be used in BT downloading and a setting for the trace server, the file information is generated according to calculation of a target file, and a calculation result is encoded according to a B encoding rule in the BitTorrent protocol, the main principle is that the file for providing downloading is virtually divided into blocks with the same size, the block size is an integer multiple of 2k (because the blocks are virtual blocks, each block file is not generated on a hard disk), and index information and a Hash verification code of each block are written into the seed file, so that the seed file is an index of the downloaded file. The downloading of file content by the downloading person needs to obtain the corresponding seed file and then uses the BT client software for downloading. During downloading, the BT client firstly analyzes the seed file to obtain a tracking address, and then connects with the tracking server. The tracking server responds to the request of the downloadable and provides the IP address of other downloadable (including the publisher) to the downloadable. The downloadable connects with other downloadable, according to the seed file, the two informs the opposite party of the own resource package, and then exchanges the data.

In the above embodiment, after the BT download is started, each user establishes a connection with other users who download the same target download file, in the downloading process, each user sends a request to other users to obtain a specific resource package, and, at the same time, when any client finishes downloading the specific resource package in the HTTP download manner, the client also informs other clients based on the connection relationship established by the users, so that the client in other clients, which does not download the specific resource package, downloads the specific resource package preferentially in the BT download manner.
In an embodiment of the present application, the method further comprises:
and under the condition that the target resource package to be downloaded is downloaded in a second downloading mode through a second connection, if the target resource package to be downloaded cannot be obtained, the target resource package to be downloaded is downloaded in a first downloading mode through a first connection, and a notice of completion of downloading the target resource package to be downloaded is sent to other clients.
In the above embodiment, in the initial downloading stage, no scarce resources are defaulted between the clients, BT downloading is defaulted between the clients, in the subsequent downloading process, if the client cannot find resources through BT downloading or the target resource package to be downloaded is scarce resources, the target resource package to be downloaded is downloaded by using HTTP downloading, and after the downloading is completed, other clients are notified, so that the client in other clients, which does not download the specific resource package, downloads the specific resource package preferentially by BT downloading.
