Abstract

An embodiment of the invention discloses a video content playing method, device and system. The method includes receiving a playing request for video content to be played and transmitted by a terminal device; selecting the optimum target Internet data center IDC node serving for the terminal device according to the playing request; acquiring the node information of the target IDC node; acquiring the real-time bandwidth of the target IDC node from the state information collected in real time; determining the code rate information of the video content to be played according to the obtained real-time bandwidth and the corresponding rule of the code rate information of the video content to be played and the code rate information; transmitting the node information of the target IDC node and the code rate information to the terminal device to enable the terminal device to select the video content to be played and adapting to the code rate information from the target IDC node to play. By means of the method, device and system, IDC bandwidth occupation can be reduced, or the IDC bandwidth utilization rate is improved.

Description

technical field [0001] The present invention relates to the field of network multimedia technology, in particular to a scheduling method, device and system for video content distribution. Background technique [0002] With the development of network multimedia technology, more and more users play some network multimedia applications, such as video and audio, through terminal devices. However, network multimedia applications, especially video, generally occupy relatively large bandwidth. When multiple users request video playback services, it will cause network congestion, causing users to be unable to quickly obtain video content. [0003] In the prior art, a CDN (Content Distribution Network, content distribution network) is used to schedule video playback requests sent by users, by adding a new layer of network architecture to the existing network. Such as figure 1 As shown, the system includes a plurality of IDC nodes 10 (Internet Data Center, Internet Data Center) and ...
