Problems solved by technology

[0003] However, in the above process, if the user only plays the audio and video for a short period of time, it will be closed (that is, the edge node only needs to send part of the playback data to the user node to meet the user's needs), while the central node sends all the playback data to the edge at one time The mode of the node (for example, the user only plays for 1 second, that is, the edge node only sends 1 second of playback data to the user node to meet the user's needs, but the central node sends 10 seconds of playback data to the edge node), will This makes the central node send unnecessary playback data, resulting in an increase in the data transmission cost of the central node, resulting in unnecessary waste of resources

Embodiment Construction

[0044] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0045] An embodiment of the present invention provides a method for sending data, which is applied to a central node in a CDN. The central node is connected to at least one edge node, and the edge node is connected to at least one user node, such as figure 1 As shown, the method includes:

[0046] Step 101: When receiving the data transmission request sent by the edge node for obtaining the cached data played on the user node, obtain the historical playback duration of at least one audio and video played by the user node in history;

[0047] Step 102: Calculate the current playback duration of the user node's current playback buffer data according to the historical playback duration of at least one audio and video;

[0048] Step 103: Based on the playing time of this time, send the cached data played by the user node to the edge node in multiple time...

Abstract

The invention discloses a data sending method, device and system, electronic equipment and a storage medium. The method comprises the following steps: when a data sending request, which is sent by an edge node and is used for obtaining cache data played at a user node, is received, obtaining the historical playing duration of at least one audio / video historically played by the user node; according to the historical playing duration of the at least one audio / video, calculating the current playing duration of the cached data played by the user node; and based on the current playing duration, sending the cached data played by the user node to the edge node in multiple times. By adopting the scheme provided by the invention, the cached data can be differentially sent for multiple times, and the sending cost of the cached data is reduced.

Description

technical field [0001] The present invention relates to the technical field of data buffering, in particular to a data sending method, device, system, electronic equipment and storage medium. Background technique [0002] At present, in the audio and video live broadcast business, after the user node initiates an audio and video playback request to the edge node, the edge node will request the playback data of the audio and video from the central node, and the central node will send the playback data to the edge node at one time. So that the edge node caches the playback data, realizing barrier-free and delay-free playback of user nodes. [0003] But in the above process, if the user only plays the audio and video for a short time, it will be closed (that is, the edge node only needs to send part of the playback data to the user node to meet the user's needs), while the central node sends all the playback data to the edge at one time The mode of the node (for example, the u...
