Problems solved by technology

[0003] 1. If users want to see real-time streams, there will be layer-by-layer forwarding in internal nodes, which will cause delays, freezes, and complicated troubleshooting, which will bring users a bad experience;
[0004] 2. Even if only one person watches the video stream, there will be layer-by-layer transfer between different CDN nodes, resulting in a large waste of bandwidth resources. At the same time, manufacturers need to lay a large number of CDN and IDC resources, and bear a large amount of hardware costs and bandwidth. waste of resources

Abstract

The invention relates to the technical field of video monitoring, in particular to a telescopic video CDN distribution system and method, and the system comprises: a real-time water line evaluation module which is used for receiving an external playing request and outputting the change trend of the water level of a current video stream system; and a video stream node tree branching and cutting module which is connected with the real-time water line evaluation module and is used for receiving the change trend of the water level of the current video stream system and carrying out node branching,node cutting recovery and node keeping according to the change trend of the water level. According to the invention, dynamic scaling of a video stream CDN is realized by using a dynamic water line assessment AI model and a multi-way tree branch and cutting method.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a scalable video CDN distribution system and method. Background technique [0002] In the video surveillance scenario, the current technology generally uses a CDN (Content Delivery Network, Content Delivery Network) distribution network after the camera is connected to the cloud. Although the CDN has been greatly improved compared with the traditional network transmission, there are also the following technical defects: [0003] 1. If users want to see real-time streams, there will be layer-by-layer forwarding in internal nodes, which will cause delays, freezes, and complicated troubleshooting, which will bring users a bad experience; [0004] 2. Even if only one person watches the video stream, there will be layer-by-layer transfer between different CDN nodes, resulting in a large waste of bandwidth resources. At the same time, manufacturers need to lay a large number ...
