Scrubbing Principle and Black Hole Threshold

Scrubbing Principle

Anti-DDoS monitors service traffic in real time. Once an attack is detected, it diverts service traffic to the Anti-DDoS scrubbing system, which identifies the traffic from that IP address, discards the attack traffic, and forwards legitimate traffic to the target IP address.

Black Hole Threshold

The black hole threshold defines the basic attack mitigation capacity. When the scale of attack exceeds the threshold, the system will adopt a black hole policy to block the IP address.

Anti-DDoS provides a 5 Gbit/s mitigation capacity against DDoS attacks free of charge.
