Background
Peer to peer (P2P) downloads may pick up data from multiple points and provide the data externally. For example, when a certain user watches a certain video at a terminal, the terminal may share the video to other users as a node, thereby saving bandwidth cost of a Content Delivery Network (CDN). Has high efficiency when the heat door resources are heated.
However, for a video being watched by a user, one video file is generally cut into a plurality of small files, and a terminal generally saves a played video in units of small files, reports relevant information to a scheduling service, and finally saves the relevant information in a remote dictionary service (Redis) cluster. Since the same popular video may be watched by more users (for example, hundreds of thousands or even millions of users) at the same time, the hash value of a small file is used as a key (key) for storage, the Redis cluster needs to store a large amount of videos, and the data amount is too large. Whereas if the Redis cluster takes the hash value of the entire video file as key, there may be a case where the p2p user only viewed a partial segment of the video, resulting in no data requested by the user.

In order to facilitate understanding of the technical solutions of the present application, some technical terms related to the present application are described below.
Peer to peer (P2P) downloads may pick up data from multiple points and provide the data externally. In general, when a user watches videos, the watched videos are retained in the cache of the terminal, and in the case of downloading P2P, the terminal may serve as a node to share the cached videos with other users. As described above, the P2P download can save the bandwidth cost of the Content Delivery Network (CDN), and is highly efficient in downloading portal resources.
Typically, a video (for example, HTTP Live Streaming (HLS)) viewed by a user is cut into small videos in a multiple Transport Stream (TS) format. The terminal saves the played (or cached) video by taking the TS as a unit, reports the progress information to a scheduling service, and finally saves the progress information to a Remote Dictionary service (Redis) cluster. In this way, when other users need to watch the video, the other users can obtain the TS file from the scheduling service, and at the same time, which terminal users have the requested TS file content, so as to obtain the TS file from the terminal.
Since there may be millions to tens of millions of users online at the same time, a popular video may be viewed by hundreds of thousands or even millions of users simultaneously, and each user may save 1 to 3 complete video files, while a video file may be divided into hundreds to thousands of ts files.
Therefore, if the hash value of the ts file is used as a key (key) to store all the user information of the ts file in the redis cluster, the redis cluster needs to store more information, and the data volume may exceed the TB level, which may cause the data volume in the redis cluster to explode and require more machines.
However, if only the hash value of the video file is taken as a key, there may be a case where a certain user only views a certain segment in the video, and thus a certain segment is also stored in the terminal thereof, so that there may be a case where data not including the data intended by the requesting user is included.
In view of the foregoing, the present application provides a peer-to-peer downloading method, which may be executed by an electronic device. An electronic device refers to a device having data processing capabilities and may be, for example, a server or a terminal. The terminal includes, but is not limited to, an id system, a smart phone, a tablet computer, a notebook computer, a Personal Digital Assistant (PDA), and the like. The server may be a cloud server, such as a central server in a central cloud computing cluster, or an edge server in an edge cloud computing cluster. Of course, the server may also be a server in a local data center. The local data center refers to a data center directly controlled by a user. In this embodiment, the electronic device may be a service scheduling device, and undertakes a service scheduling function.
Specifically, the service scheduling device obtains a download request of a requesting user including a target video file and target transport stream TS information in the target video file, and then obtains a user identification ID corresponding to the user including the target video file according to the target video file, where the user identification ID represents that the user includes the target video file. Further, TS information included in the target video file and included by the user is obtained according to the user identification ID, the user including the target transport stream TS information is determined as the target user, and then the user identification ID of the target user is returned to the requesting user, so that the requesting user can obtain the target transport stream TS information in the target video file to be downloaded according to the target user identification ID.
The service scheduling device may obtain a user identifier ID corresponding to a user including the target video file according to the target video file, and then determine whether TS information of the target video file included by the user includes target transport stream TS information according to the user identifier ID, thereby determining whether the user is determined to be the target user. The required space is small because the corresponding user identification ID is saved by taking the video file as a unit, and the TS information can be further determined according to the user identification ID, so that the method has high accuracy.
In order to make the technical solution of the present disclosure clearer and easier to understand, the following describes a peer-to-peer downloading method provided by the embodiment of the present disclosure, taking an electronic device as a service scheduling device as an example. Fig. 1 is a flowchart illustrating a peer-to-peer downloading method provided in the present application.
As shown in fig. 1, the method comprises the steps of:
s102: the service scheduling device obtains a download request of a requesting user.
The downloading request includes information of a target video file to be downloaded by a requesting user and information of a target Transport Stream (TS) in the target video file. The target video file may be represented by a hash value of the video file, which may be denoted as a cluster identifier (swarmID), for example. The TS information of the target transport stream in the target video file can be represented by a file Index number of the TS information, for example, TS Index, which indicates that the TS information is the several TS in the target video file.
S104: and the service scheduling equipment acquires the user identification ID corresponding to the user comprising the target video file according to the target video file information.
The service scheduling device includes a plurality of video files and an Identity Document (ID) of the video files. The user identifier including the video file indicates that the user equipment includes the video file, and specifically, may be any one of TS information included in the video file in the user equipment.
When a user watches the video file, the video file is included in the cache of the user terminal. When the user only watches the partial segment of the video file, the TS information corresponding to the partial segment of the video file is included in the cache.
In some possible implementations, the service scheduling device may periodically acquire P2P node information of the hot video from the redis cluster and cache the information to the local. Therefore, after acquiring the download request, the service scheduling device may acquire the user identifier ID including the target video file according to the target video file.
Specifically, the service scheduling apparatus may query a user identification ID (peerID) including the sweep ID as a value (value) with the sweep ID of the target video as a key (key). As shown in fig. 2, in the primary index, one sweep ID may be queried to obtain a plurality of user ID: peer1ID, peer2ID, etc.
S106: and the service scheduling equipment acquires the TS information in the target video file included by the user according to the user identification ID.
The user identification ID acquired by the service scheduling device is the user identification ID comprising the target video file. The service scheduling device may further query and obtain TS information of the target video file included in the user identification ID according to the obtained user identification ID.
Specifically, the service scheduling device uses the user identifier ID as a key to search and acquire the sweep ID and ts information respectively included in the user identifier ID. As shown in the secondary index of fig. 2, one peerID may correspond to one sweep ID and a plurality of TS information.
The TS information may be an index number of the target video segment in the target video file. A video file may be divided into a plurality of video segments according to a fixed length of time. For example, a video file having a duration of 1 hour may be divided into 60 video segments in units of one minute. The video segments can be indexed in chronological order, for example, a video segment with an index number of 1 represents 0 to 1 minute of a video file.
The TS information may be stored in the form of a bitmap string. The bitmap is used for marking the value corresponding to a certain element (key) by a Bit, and the Bit is used as a unit for storing data, so that the storage space can be greatly saved. As shown in fig. 2, if ts information is stored in the bitmap character string manner, it can be determined whether a corresponding ts file is stored according to whether the corresponding bit data is 1. For example, if the bit data is 1, it indicates that a ts file corresponding to the index number is stored.
The TS information may also be stored in a section manner. For example, the TS information corresponding to the user ID may be a [ startTsIndex, endTsIndex ] interval. startTsIndex represents the minimum index number of the ts file corresponding to the current user identification ID, and endTsIndex represents the maximum index number of the ts file corresponding to the current user identification ID. In some possible implementations, a vacant ts is allowed between startTsIndex and endTsIndex. When the TS information of the target transport stream of the requesting user is located within the [ startTsIndex, endTsIndex ], it indicates that the user ID owns the TS file desired by the requesting user.
S108: the service scheduling apparatus determines a user including the target transport stream TS information as a target user.
The user including the target transport stream TS information indicates that the cache of the user includes the target transport stream TS information in the target video file desired by the requesting user, so that the requesting user can obtain the target transport stream TS information from the cache of the target user. Accordingly, the service scheduling apparatus can determine a user including the target transport stream TS information as a target user.
S110: and the service scheduling equipment returns the user identification ID of the target user to the requesting user.
The target user is a user including the TS information required by the requesting user, so that after the service scheduling device returns the user identification ID of the target user to the requesting user, the requesting user can obtain the required TS information from the target user according to the user identification ID, thereby implementing point-to-point downloading.
In some possible implementation manners, the service scheduling device obtains, from the redis cluster, a user identification ID corresponding to a user including the video file and TS information in a target video file included by the user. When the TS information in the target video files respectively included by the users does not include the target transport stream TS information, the service scheduling device may obtain again the user identification ID corresponding to the user including the video file and the TS information in the target video file included by the user from the redis cluster to determine again whether the TS information in the target video files respectively included by the users includes the target transport stream TS information, thereby determining the target user.
Based on the above description, the present application provides a peer-to-peer downloading method, which may be performed by a scheduling service device. As shown in fig. 3, a requesting user inquires about which nodes have requested TS data from a scheduling service device, the scheduling service device obtains a download request of the requesting user, obtains a user identifier ID corresponding to a user including a video file according to a target video file in a REDIS cluster, obtains TS information in the target video file respectively included by the user according to the user identifier ID, determines the user including the TS information of a target transport stream as a target user, and returns the ID corresponding to the target user to the requesting user. The query of the scheduling service device based on the target video file may be performed in a redis cluster, or the corresponding information may be obtained from the redis cluster in advance. Therefore, the point-to-point downloading method with less storage capacity and high accuracy is realized.
Although the operations are depicted in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order. Under certain circumstances, multitasking and parallel processing may be advantageous.
It should be understood that the various steps recited in method embodiments of the present disclosure may be performed in a different order, and/or performed in parallel. Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.
