Embodiment Construction

[0047] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0048] 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 live video distribution network. For each live video service distributed in the live video distribution network, when the live video service is started, the global server 1 will control all video distribution network node servers responsible for the distribution of live media streams of the live video service as the live video service. The live media stream distribution allocates related network transmission resources, but the relevant video distribution network node server does not immediately start the live media stream distribution process of the live video ser...

Abstract

The invention relates to the technical field of information and communication, in particular to a passive media flow distribution method for a live video distribution network. The passive media flow distribution method for the live video distribution network aims at reducing waste of backbone network bandwidth. When a live video service is started, a video distribution network global server is used for controlling all video distribution network node servers which are in charge of the service distribution to be distribution relevant resources of the service, but a live media streaming distribution process is not started. Aiming at each live video service, both a live source station node server which receives live media streaming and a relay node server are not initiative to forward live streaming to a downstream node server. A superior node server does not forward live media streaming to a lower level node server until the lower level node server requests the superior node server to push live media streaming.

Description

technical field [0001] The invention relates to a communication network, in particular to a passive media stream distribution 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 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 servic...
