Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than those herein described, and those skilled in the art will readily appreciate that the present application may be similarly embodied without departing from the spirit or essential characteristics thereof, and therefore the present application is 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.
First, terms related to one or more embodiments of the present invention will be explained.
Bit stream protocol: i.e., bitTorrent protocol (BT protocol), which is a P2P file transfer protocol that is structured above the TCP/IP protocol, at the application layer of the TCP/IP architecture. The BitTorrent protocol itself also contains many specific content protocols and extensions, and is under constant expansion. According to the BitTorrent protocol, a file publisher generates and provides a torrent file, i.e., a seed file, from the file to be published.
Bit stream download: the main principle of bit stream (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 (no individual block files are generated on the hard disk due to the virtual division), and the index information and Hash (Hash) verification code of each block are written into a seed file (.torret).
The tracking server: i.e., a Tracker server, for collecting information about the downloadable, and providing this information to other downloadable, so that the downloadable is interconnected to transmit data.
Seed: meaning that all files in a download task are completely downloaded by a certain downloadable, which 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 comprises the address of a Tracker server required to be used in downloading the bit stream and the setting of the Tracker server, the file information is generated according to the calculation of the target file, and the calculation result is encoded according to the B encoding rule in the BitTorrent protocol.
Local service discovery protocol: the local service discovery protocol (Local Service Discovery Protocol, LSDP) provides a mechanism similar to the simple service discovery protocol (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 be used as a primary peer source for local transmissions as well as supplementing other sources running only on global unicast addresses.
Distributed hash table: i.e. DHT (Distributed Hash Table), is a distributed storage method, which does not require a central node server, but rather each client is responsible for a small range of routes and for storing a small portion of data, thus enabling the addressing and storage of the whole DHT network. Unlike 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 next nodes nearby 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 key, 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, and detailed descriptions are provided in the following embodiments.
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, a memory 110 and a processor 120. Processor 120 is coupled to memory 110 via bus 130 and database 150 is used to store data.

It should be understood that the block diagram of the computing device shown in FIG. 1 is for exemplary purposes only and is not intended to limit the scope of the present description.

Wherein the processor 120 may perform the steps of the method shown in fig. 2. Fig. 2 is a schematic flow chart illustrating a file downloading method according to an embodiment of the present application, applied to a download initiating node in a local area network, comprising steps 202 to 206.
Step 202: and obtaining the feature identifiers corresponding to the at least two files to be downloaded respectively, and generating a feature identifier list.
The application adjusts the bit stream protocol, thereby adding the characteristic identification 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 a game file, the game file can comprise a map file, a character model file, an animation special effect file, a program file and the like, and the corresponding characteristic identification can be respectively added to the map file, the character model file, the animation special effect file and the program file through the adjusted bit stream protocol.
In an embodiment of the present application, the step 202 specifically includes steps 302 to 304.
Step 302: and respectively acquiring seed files corresponding to at least two files to be downloaded, and acquiring the characteristic identifiers corresponding to each file to be downloaded according to the seed files corresponding to each file to be downloaded.
For a plurality of download initiating nodes which are connected with each other in a local area network, the download initiating nodes comprise, but are not limited to, a computer terminal, an intelligent terminal, a server and the like, and when a download platform running on any download initiating node needs to download at least two files to be downloaded, the download platform respectively acquires seed files corresponding to each file to be downloaded, and acquires feature identifiers corresponding to each file to be downloaded from the seed files corresponding to each file to be downloaded, wherein the feature identifiers can be hash values generated by a secure hash algorithm (Secure Hash Algorithm).
It should be noted that in the standard bit stream protocol, the file to be downloaded is split into a plurality of data blocks to be downloaded, and each data block to be downloaded corresponds to one hash value, so that a complete hash value set is formed for identifying the whole file to be downloaded, and therefore, the application can also be identified by taking the hash value set corresponding to the file to be downloaded as a feature.
Step 304: and generating the feature identifier list according to the feature identifiers corresponding to each file to be downloaded.
Further, by aggregating the feature identifiers corresponding to each file to be downloaded, at least two feature identifier lists corresponding to the files to be downloaded are constructed, for example, for the file to be downloaded a and the file to be downloaded B, the file to be downloaded a includes a data block a1, a data block a2 and a data block a3, the file to be downloaded B includes a data block B1, a data block B2 and a data block B3, and the feature identifiers Id corresponding to the data block a1 are respectively obtained a1 Characteristic identifier Id corresponding to data block a2 a2 Characteristic identifier Id corresponding to data block a3 a3 And the characteristic identifier Id corresponding to the data block b1 b1 Characteristic identifier Id corresponding to data block b2 b2 Characteristic identifier Id corresponding to data block b3 b3 Thereby constructing a feature identification list { Id } a1 、Id a2 、Id a3 、Id b1 、Id b2 、Id b3 }。
According to the method and the device, the BT protocol is adjusted, and the characteristic identification for identifying the specific content of the current downloaded file is added, so that the downloading platform can analyze a plurality of downloaded files at the same time, and the problem that only one hash value can be matched in the marking bit stream protocol is avoided.
Step 204: searching at least one neighbor node corresponding to the downloading initiating node in the local area network, and sending broadcast information containing the characteristic identification list to each neighbor node.
In an embodiment of the present application, the step 204 specifically includes steps 402 to 404.
Step 402: and announcing the existence of the downloading initiating node to all neighbor nodes in the local area network through a local service discovery protocol.
The application searches other neighbor nodes adjacent to the download initiating node running the download platform in the local area network through the local service discovery protocol, and announces the existence of the download initiating node to each neighbor node.
Step 404: and transmitting broadcast information containing the characteristic identification list to each neighbor node in the local area network through a user datagram protocol.
Further, the download initiating node running the download platform sends broadcast information containing the feature identification list to each neighbor node in the local area network through the user datagram protocol, so that each neighbor node can receive the feature identification list, and each file to be downloaded, which needs to be downloaded by the download platform, is determined according to each feature identification in the feature identification list.
The application discovers the neighbor node through the local service discovery protocol, so that the neighbor node of the download initiating node can analyze at least two files to be downloaded required by the download initiating node, and thus, download connection is respectively established with the download initiating node in a bit stream downloading mode, the download platform can download the at least two files to be downloaded simultaneously, and the downloading 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 application, through optimizing and adjusting the bit stream protocol, the unique characteristic identifiers for identifying the files to be downloaded are added, and a plurality of formed characteristic identifiers are recorded in the characteristic identifier 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 downloading a plurality of files simultaneously is realized.
In an 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 characteristic identification list with a local download list.
Specifically, after each neighbor node obtains the feature identification list, each neighbor node invokes a download list local to the neighbor node, and checks the feature identification list with the download list.
Step 504: judging whether the download list contains files to be downloaded corresponding to any feature identifier in the feature identifier list; if yes, go to step 506; if not, ending.
Further, each neighbor node analyzes the feature identification list to determine a corresponding data block of each feature identification column in the feature identification list, and then judges whether the neighbor node has downloaded any corresponding data block according to a downloading list of the neighbor node.
Step 506: and the at least one neighbor node establishes 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 downloading initiating node.
In the above embodiment, if any one of the at least two files to be downloaded has already been downloaded in at least one neighboring node, the at least one neighboring node establishes a bit stream downloading connection with the downloading initiating node, and the downloading initiating node requests the at least one neighboring node to download the data blocks in the at least two files to be downloaded, so that the at least one neighboring node transmits the data blocks in the at least two files to be downloaded to the downloading initiating node synchronously, thereby realizing that the downloading platform of the present application can download a plurality of files to be downloaded simultaneously.
The application analyzes at least two files to be downloaded which need to be downloaded by the downloading platform through the neighbor nodes in the local area on the basis of adjusting the bit stream protocol aiming at the downloading initiating node in the local area, and establishes bit stream connection with the downloading initiating node respectively, thereby enabling the downloading initiating node to simultaneously download at least two files to be downloaded, greatly improving the downloading efficiency and saving the time required by downloading.
Wherein the processor 120 may also perform the steps of the method shown in fig. 6.

Step S6021: and respectively acquiring seed files corresponding to at least two files to be downloaded, and acquiring the characteristic identifiers corresponding to each file to be downloaded according to the seed files corresponding to each file to be downloaded.
In which step S6021 is the same as step 302, the details of step 302 may be referred to, and the disclosure is not repeated here.
Step S6022: and generating the feature identifier list according to the feature identifiers corresponding to each file to be downloaded.
The step S6022 is the same as the step 304, and the disclosure of step S304 may be referred to herein.
Step 604: and communicating with a tracking server and transmitting the characteristic identification list to the tracking server.
In the above embodiment, since in the wide area network, the network node cannot directly obtain the internet protocol address (Internet Protocol Address) of the network node in the other wide area network, for this purpose, the download initiating node running the download platform needs to communicate with the tracking server, and send the feature identifier list to the tracking server.
Step 606: and establishing connection with at least one network node according to a tracking result returned by the tracking server, so that the downloading initiating node downloads the at least two files to be downloaded synchronously.

S605: and searching for a target network node with the at least two files to be downloaded from at least one network node according to the characteristic identification list.
S607: and synchronously downloading the at least two files to be downloaded through the target network node.
It should be noted that tracking servers and subsequently developed DHT's are commonly used for bit stream downloads for wide area networks, but if a stable server exists in a particular application, it is possible to use the current stable server as the tracking server, so that no DHT network has to be set up, and the application is not limited herein.
Correspondingly, the processor 120 may also perform the steps of the method shown in fig. 7. Fig. 7 is a schematic flow chart diagram illustrating a file downloading method applied to a tracking server in a wide area network according to an embodiment of the present application, including steps 702 to 708.
Step 702: and acquiring a characteristic identification list sent by the downloading initiating node.

Step 704: and determining at least two files to be downloaded which need to be downloaded by the downloading initiating node according to at least two feature identifiers in the feature identifier list.
In the above embodiment, the tracking server analyzes and identifies the feature identifier in the feature identifier list, so as to determine at least two files to be downloaded that need to be downloaded by the download initiating node and a plurality of data blocks corresponding to each downloaded file.
Step 706: and determining at least one network node which is downloading the at least two files to be downloaded according to the downloading list recorded by the tracking server.
In the above embodiment, the internet protocol addresses of a plurality of network nodes in the wide area network are recorded in the download list of the tracking server, and the file or the data block downloaded correspondingly for each network node in a specific time period is also recorded in the download list. Thus, the tracking server is able to compare the at least two files to be downloaded with the files in the download list, thereby determining at least one network node that is downloading the at least two files to be downloaded.
