Anti-DDoS allows you to limit traffic rate for business IPs and ports.
You have purchased an Anti-DDoS Advanced (Global Enterprise Edition) instance and set your target to protect.
Log in to the Anti-DDoS Advanced (Global Enterprise Edition) Console and select Anti-DDoS Advanced -> Configurations on the left sidebar.
Select an Anti-DDoS Advanced instance ID in the list on the left, such as "xxx.xx.xx.xx bgpip-000003n2".
Click Set in the IP/Port Speed Limit section on the right.
In the pop-up window, select a protocol for the port you set, set a rate limit, and then click OK.
Now the new rate limiting rule is added to the list, and you can click Configuration to modify it.
