Tencent Cloud CDN supports downstream speed limit configuration for setting the maximum downstream throughput speed over one single URL on the server.
The downstream speed limit configuration can control the peak bandwidth of CDN to a certain degree. It is frequently used in scenarios such as ecommerce promotions and new game version releases and updates.
Note:
The downstream speed limit configuration takes effect globally for all users who access the domain name. After the downstream speed limit is configured, the user access experience and CDN acceleration effect may be affected. Therefore, configure the downstream speed limit with caution.
Directions
Viewing the configuration
Log in to the CDN console, select Domain Management on the left sidebar, and click Manage on the right of a domain name to enter its configuration page. Open the Access Control tab to find the Downstream Speed Limit Configuration section. The Downstream Speed Limit switch is toggled off by default.
Adding rules
Click Add Speed Limit Rule to configure a rule:
Configuration limitations

Configuration Samples
The downstream speed limit configuration of cloud.tencent.com is as follows:
If a user accesses the resource http://cloud.tencent.com/test.mp4, the server will return the content at the configured downstream speed of 200 KB/s.
If a user accesses the resource http://cloud.tencent.com/test.flv, the server will return the content at the configured downstream speed of 400 KB/s.
