Embodiment Construction

[0132] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0133] Before explaining the embodiment of the present application in detail, the system structure involved in the embodiment of the present application is firstly introduced.

[0134] figure 1 It is a schematic diagram of the P2P live broadcast system involved in the embodiment of the present application. Such as figure 1 As shown, the P2P live broadcast system includes a CDN server 10 , a P2P server 20 , multiple root nodes 30 , multiple child nodes 40 , and a retransmission server 50 .

[0135] Wherein, the CDN server 10 may send video streams in FLV format to multiple root nodes 30 . Each root node 30 may divide the received video stream in FLV format into multiple sub-streams. Each sub-node 40 can obtain at least one sub-strea...

Abstract

The invention discloses a method and a device for adjusting a root node in a peer-to-peer network live broadcast system. According to the method, the root node up-regulation quantity and the root nodedown-regulation quantity are determined by acquiring the total number of forced subscription sub-streams and the total number of idle sub-streams within the first time length, so that a plurality ofroot nodes in the P2P live broadcast system are regulated according to the root node up-regulation quantity and the root node down-regulation quantity. Namely, the CDN server does not need to select the root node according to the number of the root nodes of each substream. According to the method and the device, the problem that the root node cannot be adjusted when the video stream pushed by theCDN server is the FLV format video stream in the prior art is solved, so that the sharing rate when the CDN server pushes the FLV format video stream is effectively improved.

Description

technical field [0001] The present application relates to the field of live broadcast technology, and in particular to a method, device and storage medium for adjusting a root node in a peer-to-peer network live broadcast system. Background technique [0002] In order to solve the problems of high pressure on server resources and bandwidth and low video quality in the C / S live video mode, the industry has proposed a P2P live broadcast system based on P2P (peer to peer, peer-to-peer network) technology. Wherein, the P2P live broadcast system includes a Content Delivery Network (Content Delivery Network, CDN) server, a P2P server, multiple root nodes and multiple sub-nodes. Wherein, multiple root nodes refer to terminals that obtain video streams from a CDN server, and multiple sub-nodes refer to terminals that obtain video streams from the root node or other sub-nodes. [0003] In related technologies, a video stream in a P2P live broadcast system can be divided into n sub-s...
