Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.
The terminology used in the description of the one or more embodiments is for the purpose of describing the particular embodiments only and is not intended to be limiting of the description of the one or more embodiments. As used in one or more embodiments of the present specification 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 and all possible combinations of one or more of the associated listed items.
It will be understood that, although the terms first, second, etc. may be used herein in one or more embodiments 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 can also be referred to as a second and, similarly, a second can also be referred to as a first without departing from the scope of one or more embodiments of the present description.
First, the noun terms to which one or more embodiments of the present invention relate are explained.
Bit stream protocol: namely, the BitTorrent protocol (BT protocol), which is a P2P file transfer protocol built on top of the TCP/IP protocol, at the application layer of the TCP/IP architecture. The BitTorrent protocol itself also contains many specific content protocols and extension protocols, and is expanding. According to the BitTorrent protocol, a file publisher will provide a torrent file, i.e., a torrent file, from the file to be published.
Bit stream downloading: the main principle of Bitstream (BT) downloading is to virtually divide the file providing the download into equal-sized blocks, the block size must be an integer power of 2k (since it is a virtual partition, no individual block file is generated on the hard disk), and write the index information and Hash (Hash) verification code of each block into the seed file (. torrent).
A tracking server: namely, the Tracker server, is used for collecting the information of the downloader, and provides the information to other downloaders, so that the downloaders are mutually connected to transmit data.
Seed: all files in a downloading task are completely downloaded by a certain downloader, and the downloader becomes a seed. The file published by the publisher itself is the primordial seed. The torrent file is essentially a text file and comprises two parts, namely Tracker information and file information. The Tracker information mainly includes addresses of Tracker servers required in bit stream downloading and settings for the Tracker servers, the file information is generated according to calculation of target files, and calculation results are encoded according to B encoding rules in a BitTorrent protocol.
Local service discovery protocol: local Service Discovery Protocol (LSDP) provides a mechanism similar to Simple Service Discovery Protocol (SSDP) for discovering devices and services within a Local area network to advertise presence in a particular group to Local neighbors. It can either serve as the primary peer source for local transmissions or supplement other sources that only run on global unicast addresses.
Distributed hash table: namely, DHT (distributed Hash table), is a distributed storage method, and this kind of network does not need a central node server, but each client is responsible for a small range of routing and for storing a small part of data, thereby implementing addressing and storage of the whole DHT network. Different from the central node server, each node in the DHT network does not need to maintain the information of the whole network, but only stores the information of the adjacent subsequent nodes in the node, thereby greatly reducing the occupation of bandwidth and the consumption of resources. The DHT network also copies the backup redundant information on the node closest to the keyword, thereby avoiding the problem of single node failure.
In the present application, a file downloading method and apparatus, a computing device and a computer readable storage medium are provided, which are described in detail in the following embodiments one by one.
FIG. 1 shows a block diagram of a computing device 100, according to an embodiment of the present description. The components of the computing device 100 include, but are not limited to, memory 110 and processor 120. The processor 120 is coupled to the memory 110 via a bus 130 and a database 150 is used to store data.

Step 202: and acquiring the characteristic identifiers corresponding to at least two files to be downloaded respectively, and generating a characteristic identifier list.
By adjusting the bit stream protocol, the method and the device for downloading the game file add the feature identifier for identifying the corresponding specific content of each data block in the file to be downloaded, for example, in the case that the file to be downloaded is the game file, the game file may include a map file, a character model file, an animation special effect file, a program file, and the like, and the adjusted bit stream protocol may add the corresponding feature identifier to the map file, the character model file, the animation special effect file, and the program file, respectively.
In the embodiment of the present application, the step 202 specifically includes steps 302 to 304.
Step 302: the method comprises the steps of respectively obtaining seed files corresponding to at least two files to be downloaded, and obtaining a characteristic identifier corresponding to each file to be downloaded according to the seed file corresponding to each file to be downloaded.
For a plurality of download initiating nodes which are mutually connected in a local area network, the download initiating nodes include but are not limited to a computer terminal, an intelligent terminal, a server and the like, under the condition that a download platform running on any download initiating node needs to download at least two files to be downloaded, the download platform respectively obtains a seed file corresponding to each file to be downloaded, and obtains a feature identifier corresponding to each file to be downloaded from the seed file corresponding to each file to be downloaded, wherein the feature identifier can be a Hash value generated by a Secure Hash Algorithm (Secure Hash Algorithm).
It should be noted that, in a standard bitstream protocol, the file to be downloaded may be split into a plurality of data blocks to be downloaded, and each data block to be downloaded may correspond to one hash value to form a set of complete hash value sets for identifying the whole file to be downloaded, and therefore, the present application may also use the hash value set corresponding to the file to be downloaded as the feature identifier.
Step 304: and generating the characteristic identifier list according to the characteristic identifier corresponding to each file to be downloaded.
Further, a feature identifier list corresponding to at least two files to be downloaded is constructed by collecting feature identifiers corresponding to each file to be downloaded, for example, for a file a to be downloaded and a file B to be downloaded, the file a to be downloaded includes a data block a1, a data block a2 and a data block a3, the file B to be downloaded includes a data block B1, a data block B2 and a data block B3, and feature identifiers Id corresponding to the data block a1 are respectively obtaineda1The characteristic identifier Id corresponding to the data block a2a2The characteristic identity Id corresponding to the data block a3a3And the characteristic identifier Id corresponding to the data block b1b1The characteristic identifier Id corresponding to the data block b2b2The characteristic identity Id corresponding to the data block b3b3Thereby formingBuild a list of feature identifiers (Id)a1、Ida2、Ida3、Idb1、Idb2、Idb3}。
According to the method and the device, the BT protocol is adjusted, and the characteristic mark for marking the specific content of the current download file is added, so that the download platform can simultaneously analyze a plurality of download files, and the problem that only one hash value can be matched in the labeling bit stream protocol is solved.

Step 404: and sending the broadcast information containing the characteristic identification list to each neighbor node in the local area network through a user datagram protocol.
Further, a download initiating node operating the download platform sends broadcast information containing the feature identifier list to each neighbor node in a local area network through a user datagram protocol, so that each neighbor node can receive the feature identifier list, and each file to be downloaded, which needs to be downloaded by the download platform, is determined according to each feature identifier in the feature identifier list.
According to the method and the device, the neighbor nodes are discovered through the local service discovery protocol, so that the neighbor nodes of the download initiating node can analyze at least two files to be downloaded, which are required to be downloaded by the download initiating node, and then download connection is respectively established with the download initiating node through a bit stream downloading mode, so that the download platform can download the at least two files to be downloaded simultaneously, and the download time is saved.
Step 206: and establishing connection with the at least one neighbor node according to the response of the at least one neighbor node to the broadcast information, and synchronously downloading the at least two files to be downloaded from the at least one neighbor node.
According to the method and the device, the bit stream protocol is optimized and adjusted, the unique characteristic mark for marking the files to be downloaded is added, and the formed characteristic marks are recorded in the characteristic mark list, so that the node can synchronously acquire a plurality of files to be downloaded when requesting the files through a P2P mechanism, and a downloading platform for simultaneously downloading a plurality of files is realized.
In the embodiment of the present application, the step 206 specifically includes steps 502 to 510.
Step 502: and each neighbor node in the at least one neighbor node checks the acquired feature identification list with a local download list.
Specifically, after each neighbor node acquires the feature identifier list, the local download list of each neighbor node is called, and the feature identifier list is checked with the download list.
Step 504: judging whether the download list contains a file to be downloaded corresponding to any feature identifier in the feature identifier list; if yes, go to step 506; if not, the process is ended.
Furthermore, each neighbor node analyzes the feature identifier list to determine the data block corresponding to each feature identifier column in the feature identifier list, and then judges whether the neighbor node has downloaded any corresponding data block according to the download list of the neighbor node.
Step 506: the at least one neighbor node establishes a connection with the download initiating node.
Step 508: and the download initiating node respectively requests at least two files to be downloaded from the at least one neighbor node.
Step 510: and the at least one neighbor node synchronously transmits the at least two files to be downloaded to the download initiating node.
In the above embodiment, if any data block in the at least two files to be downloaded has been downloaded in at least one neighbor node, the at least one neighbor node establishes a bit stream downloading connection with the download initiating node, and the download initiating node requests the at least one neighbor node to download the data blocks in the at least two files to be downloaded, so that the at least one neighbor node transmits the data blocks in the at least two files to be downloaded to the download initiating node synchronously, and the download platform of the present application can download a plurality of files to be downloaded simultaneously.
According to the method and the device, on the basis of adjusting the bit stream protocol, at least two files to be downloaded, which need to be downloaded by a downloading platform, are analyzed by neighbor nodes in a local area, and bit stream connection is respectively established with the downloading initiating node, so that the downloading initiating node can simultaneously download the at least two files to be downloaded, the downloading efficiency is greatly improved, and the time required by downloading is saved.

Step 604: and communicating with a tracking server and sending the feature identifier list to the tracking server.
In the above embodiment, since a network node cannot directly obtain an Internet Protocol Address (Internet Protocol Address) of a network node in another wide area network in the wide area network, a download initiating node operating the download platform needs to communicate with a tracking server and send the feature identifier list to the tracking server.
