Problems solved by technology
The use of CDN traffic in the existing technology fluctuates greatly. According to statistics, among the CDN traffic used by enterprises every month, the maximum CDN traffic is 140G, the minimum CDN traffic is 5G, and the average CDN traffic is 40G. The distribution of CDN traffic usage varies. Uniform, and when the current CDN traffic is greater than the maximum available traffic, the maintenance personnel need to manually control the channel probability of the download channel to reduce the CDN traffic, where the channel refers to the channel for downloading files, and the channel probability refers to the number of users allowed to access the target file. The proportion of users who download the target file, maintenance personnel usually take a long time to find and solve problems, and the probability of manual channel control is not accurate, which will lead to a surge in CDN traffic and network congestion

The embodiment of the present invention discloses a content distribution network traffic control method, device, and terminal, wherein the content distribution network traffic control method includes: acquiring the current CDN traffic collected last time and the last collected data for the download channel according to the preset collection period The last CND traffic; when the difference between the current CDN traffic and the last CDN traffic exceeds the preset range, the channel probability of the download channel is adjusted; according to the adjusted channel probability, the target file is allowed to be downloaded through the download channel within a unit of time. percentage of users. By adopting the embodiment of the present invention, the channel probability can be adjusted to control CDN traffic, and avoid network congestion caused by sudden increase of CDN traffic.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular to a content distribution network flow control method, device and terminal. Background technique [0002] CDN (Content Delivery Network, Content Distribution Network) is an effective means to solve problems such as poor Internet performance that first emerged in the United States in recent years and developed rapidly. The bottleneck and link of speed and stability make content transmission faster and more stable. By placing a layer of intelligent virtual network based on the existing Internet based on node servers placed everywhere in the network, the CDN system can real-time according to the network traffic and the connection of each node, the load status, the distance to the user and the response time and other comprehensive information to redirect the user's request to the service node closest to the user. [0003] CDN traffic refers to the total traffic of...
