ADVANTAGES OF PROPOSED SYSTEM: D-PID does help preventing DDoS flooding attacks since it not only imposes significant overhead for the attacker to launch DDoS flooding attacks, but also makes it easier for the network to detect the attacker. Surprisingly, achieving such benefits only incurs little overheads. Our simulation results show that the number of extra content request messages caused by D-PID is only 1.4% or 2.2% (by using different data traces), when the update period is 300 seconds. PID Even if the update period is 30 seconds, the peak update rate of a PID PID domain is less than 10 per second with a probability higher than 95%, and the maximal update rate of all domains is 202 per second, which is PID significantly less than the peak update rate (1,962 per second) of IP-prefixes in the current Internet. To the best of our knowledge, this work is the first step toward using dynamic to defend against DDoS flooding attacks PIDs SYSTEM ARCHITECTURE:
