Embodiment Construction

[0066] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0067] 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. In the existing solution, the live video distribution tree of the live video service is pre-configured when the live video service registers with the video distribution network, including all video distribution network node servers responsible for the live media stream distribution of the live video service A collect...

Abstract

The invention relates to the technical field of information and communication, in particular to a method of managing dynamic network distribution trees of a video live broadcast distribution network. Aiming at each video live broadcast service, an independent video live broadcast distribution trees are set up in the video live broadcast distribution network. The video live broadcast distribution trees of the video live broadcast services are not in static allocation when the video live broadcast services are registered rather than in dynamic creation when a user client-side applying the access services of the video live broadcast services triggers the dynamic creation process of the video live broadcast distribution trees, when the video live broadcast services are played. When the last receiving user of the video live broadcast services stops receiving the services, the dynamic dismantling process of the video live broadcast distribution trees is triggered, and the video broadcast distribution trees of the video broadcast services are dismantled dynamically.

Description

technical field [0001] The invention relates to a communication network, in particular to a dynamic network distribution tree management method of 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 day by day, and the large-scale video traffic distribution based on the Internet has become 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 services, it is possible to impr...
