Description
Clean bandwidth
50 Mbps
20 Mbps
The maximum service traffic that the instance can process when no attacks occur. You can increase this specification.
Clean QPS
500
1,000
The maximum number of concurrent HTTP and HTTPS requests per second that the instance can process when no attacks occur. You can increase this specification.
NoteSet this parameter based on your service usage. If the actual QPS of your service exceeds the specified clean QPS, packet loss may occur and full logs may not be recorded completely.
Function plan
Standard Package
Standard Package
Anti-DDoS Proxy supports Standard and Enhanced function plans. The Enhanced function plan improves the service access and DDoS attack mitigation capabilities of Anti-DDoS Proxy.
For more information, see Differences between the Standard and Enhanced function plans.
