If the mix of traffic on the interface does not change, p will slowly converge to a value that keeps the queue within its bounds with full link utilization.
Many scheduling algorithms, including the fairness-aimed ones, are notably vulnerable to spoofing distributed denial-of-service (DDoS) attacks.
A resilient stochastic fair Blue (RSFB) algorithm was proposed in 2009 against spoofing DDoS attacks.
The basic idea behind RSFB is to record the responsive normal TCP flows and rescue their dropped packets.
RSFB algorithm is effective in preserving the TCP throughput in the presence of spoofing DDoS attacks.
