Embodiment 1

[0031] A method for realizing seamless disaster recovery of video-on-demand based on HLS of the present invention is a method for realizing seamless disaster recovery of video-on-demand in a video-on-demand system. The video-on-demand system includes a server, a network, a client, and a server and a client Through network communication; on the server side, by adding multiple servers and adopting a load balancing method to form a streaming scheduling server group, the streaming scheduling server group monitors the health information and load information of all streaming servers under its jurisdiction in real time through the heartbeat mechanism; customers All user video-on-demand requests on the terminal are intercepted and recorded by the streaming scheduling server group first, and the streaming scheduling server group assigns healthy streaming servers to the client to provide video streaming services; when a streaming server fails, The streaming scheduling server group switch...

Abstract

The invention discloses a method for realizing video on demand seamless disaster tolerance based on HLS (HTTP Live Streaming), belongs to the technical field of video on demand, and solves the problem of delay or incapability of watching due to failure of a streaming server when a user requests video on demand. According to the technical scheme, the method comprises the following steps: constructing a streaming scheduling server group on a server side by using a plurality of servers in a load balancing way, and monitoring health information and load information about all managed streaming servers in real time through a heartbeat mechanism by using the streaming scheduling server group; intercepting all user video on demand requests on a client by using the streaming scheduling server group, recording the user video on demand requests, allocating healthy streaming servers to the client by using the streaming scheduling server group, and providing video streaming services; and when a certain streaming server fails, switching to other streaming servers according to a current user video on demand request by using the streaming scheduling server group, and providing video streaming services for the client by using other streaming servers in order to realize seamless disaster tolerance.

Description

[0001] technical field [0002] The invention relates to the technical field of video-on-demand, in particular to a method for realizing seamless disaster recovery of video-on-demand based on HLS. Background technique [0003] HLS (HTTP Live Streaming) is a streaming media transmission protocol implemented by Apple based on HTTP. The feature of HLS is that the server slices and stores the video source files, and generates m3u8 index files. Each slice file is described in the m3u8 file, and the client downloads and plays progressively according to the order of the TS files described in m3u8. HLS has the following advantages: 1. The network transmission is convenient, and the data is transmitted through the HTTP protocol, so there is no need to consider the problem of firewall or proxy; 2. The client can reduce the load of the backbone network by progressive downloading; 3. The client can download according to Dynamically adjust the video playback bit rate according to the ne...
