In this paper, the authors aim at the evaluation of queuing algorithms using NS2 simulator. The recent LDDoS attacks cause more severe damage to the TCP based applications than the traditional DDoS attacks. The Congestion Participation Rate (CPR) approach is used for detection and prevention of LDDoS attacks. Earlier approaches can only detect the LDDoS attacks. The CPR approach using queuing management algorithms shows better results than the DFT approach. The simulations are done using various parameters such as throughput, delay and bandwidth.
