Application Scenarios
Anti-DDoS provides anti-DDoS only for HUAWEI CLOUD public IP addresses.
Anti-DDoS devices are deployed at egresses of data centers. Figure 1 shows the network topology.
The detection center detects network access traffic according to user-configured security policies. If an attack is detected, traffic is diverted to cleaning devices for real-time defense. Abnormal traffic is cleaned, and legitimate traffic is forwarded.
Anti-DDoS provides a 500 Mbit/s mitigation capacity against DDoS attacks for free. Traffic that exceeds 500 Mbit/s from the attacked public IP address will be routed to the black hole and the legitimate traffic will be discarded. Therefore if you may suffer from volumetric attacks exceeding 500 Mbit/s, it is a better choice to purchase HUAWEI CLOUD Advanced Anti-DDoS (AAD) for enhanced protection.
