摘要：In this paper, we are going to present the simulation results of comparison of five queuing algorithms (Drop Tail, Fair Queuing, Stochastic Fair Queuing, Deficit Round Robin and Random Early Detection) using ns-2 as simulation environment. Comparison of the queuing algorithms is based on attack-intensity. We are checking the performance of each queuing algorithm on a particular queue limit against different attack intensities. Here an attempt has been made to cover an overview of Denial of Service (DoS) attack, Distributed Denial of Service (DDoS) attack, methods of attack, DDoS attack tool kits and queuing algorithms. The results in this paper also indicate that UDP type attack traffic is more powerful as compared to TCP type attack in terms of bandwidth consumption.
