What is an advanced mitigation session?
| Service | Instance type | Number of advanced mitigation sessions that are provided free of charge per calendar month |
|---|---|---|
| Anti-DDoS Pro | Advanced | Two sessions |
| Anti-DDoS Premium | Insurance | Two sessions |
| Secure Chinese Mainland Acceleration (Sec-CMA) Note An instance of the Sec-CMA mitigation plan and an instance of the Sec-CMA (Basic) mitigation plan have the same specifications except the number of advanced mitigation sessions that are provided free of charge per calendar month. | Two sessions | |
| Sec-CMA (Basic) | One session |
If the advanced mitigation sessions that are provided free of charge per calendar month cannot meet your business requirements, we recommend that you purchase global advanced mitigation sessions. If the advanced mitigation sessions that are provided free of charge are exhausted within a calendar month and a volumetric attack whose traffic exceeds the clean bandwidth of your instance occurs, Anti-DDoS Pro or Anti-DDoS Premium starts to consume the global advanced mitigation sessions that you purchased to protect your service. The following table describes the types of global advanced mitigation sessions.
