Problems solved by technology

[0007] In a large-scale live video distribution network, multiple edge servers located in the same geographical location may all need to request the same live video stream from relay node servers deployed in different places, which will cause multiple live video streams with the same content to Transmission on the backbone network causes a waste of backbone network bandwidth, and also increases the transmission load of the relay node server

Embodiment Construction

[0041] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] Such as figure 1 As shown, in the live video distribution network, as the global server of the video distribution network, the global server 1 is responsible for centralized control, management, monitoring and scheduling of all video distribution network node servers in the network. For each live video service distributed in the network, the global server 1 will create an independent live video distribution tree for it to be responsible for the real-time distribution of the live media stream of the live video service.

[0043] In the existing implementation scheme, the live video distribution tree of the live video service is established when the live video service registers with the video distribution network, and the video distribution network responsible for the distribution of the live video service is pre-configured by the glo...

Abstract

The invention relates to the technical field of information and communication, in particular to a method of managing cluster type dynamic network distribution trees of a video live broadcast distribution network. The method of managing the cluster type dynamic network distribution trees of the video live broadcast distribution network aims to further reduce the needs of video live broadcast services on network transmission bandwidth and reduce the transmission load of a relay node server. When a fringe node server needs to access the video live broadcast distribution trees of one video live broadcast serve, a video distribution network global server firstly searches a video distribution network node server nearest to the fringe node server in the video live broadcast distribution trees, and distributes the video distribution network node server to the fringe node server as the higher-level access node of the fringe node server, and therefore the fringe node servers located on identical geographic positions are enabled not to acquire an identical media stream from a far-end relay node server repeatedly.

Description

technical field [0001] The invention relates to a communication network, in particular to a clustering dynamic network distribution tree management method of a live video distribution network in a live video distribution network. Background technique [0002] With the wide application of video technology, the demand for live video services based on the Internet is increasing, and the large-scale video traffic distribution based on the Internet is a severe challenge for live video services. Although CDN technology is widely used to distribute web traffic and video-on-demand traffic, realize nearby access to network content, alleviate the pressure brought by the high throughput rate of streaming media transmission on backbone network bandwidth, and improve service response speed, but the current CDN technology cannot It is a good solution to the traffic distribution problem of large-scale live video services. [0003] Such as figure 1 As shown, for large-scale live video ser...
