Abstract

The invention provides a video CDN (Content Delivery Network) scheduling optimization method and device. The method is applied to a scheduling server. On the basis of traffic control, a target scheduling server requested by a client is synthesized. In general, the target scheduling server is determined by the client based on own practical downloading speed, so through combination of an emergency parameter and a target operation state of the scheduling server, a video server is allocated for a scheduling request, traffic and downloading speed demands can be satisfied to the greatest extent, andthe problem that the scheduling server cannot take the downloading speed and traffic control into consideration at the same time can be mitigated or even avoided.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, to a video CDN scheduling optimization method and device. Background technique [0002] A video CDN (Content Delivery Network, content distribution network) system is a system capable of providing video streaming services. In the video CDN system, the role of the scheduling server is to designate the video server for the user to download video file fragments. [0003] Currently, there are two scheduling strategies commonly used by the scheduling server. The commonly used one is a flow control strategy, and the other is a scheduling strategy based on user download speeds. For the first scheduling strategy, the scheduling server allocates video servers to users according to the traffic control ratio in a certain scheduling area, but because the download speed is not considered, the client is prone to playback freezes. For the second scheduling strategy,...
