Video network system, back-to-source network node device, method and storage medium

Abstract

The invention discloses a video network system, a data center device, a back-to-source network node device, an edge network node device, a video data distribution method and a storage medium. The method comprises the following steps: when a back-to-source calling request of video data, sent by the edge network node device, is received by the back-to-source network node device, judging whether theback-to-source network node device stores the video data; if so, sending the video data to the edge network node device; and if not, sending the back-to-source calling request to the data center device by the back-to-source network node device, receiving the video data fed back by the data center device and sending the video data to the edge network node device. By the technical scheme of the invention, bandwidth resource occupation of a computer room can be reduced, bandwidth cost is reduced, moreover, data processing pressure of the data center device is reduced.

Description

technical field [0001] The present invention relates to the technical field of video data processing, in particular to a video network system, data center equipment, back-to-source network node equipment, edge network node equipment, a video data processing method, a video data distribution method, and a computer-readable storage medium. Background technique [0002] At present, for the field of live video broadcasting, the architecture of the live broadcast network system is usually that the live broadcast end device provides the live video data to one or more data center devices through the source station server (the data center device includes one or more servers, and each data center device can Corresponding to different pre-determined regions, for example, one data center device can correspond to the South China region of China and provide communication support for the computer room in the region, and another data center device can correspond to the North China region of...

AI Technical Summary

Problems solved by technology

[0004] The existing data center equipment and each network node equipment carry out direct video live broadcast content back-to-source retrieval schemes. The existing technical defects are: the bandwidth resource occupation of the computer room is serious, and the bandwidth cost of the computer room is high; the data center equipment The resource consumption is large, the data processing pressure is high, and the response ability is greatly reduced
