Simulation and Comparison of Various Queuing Algo-rithms based on their Performance using CPR Approach in Detection of LDDoS Attacks

this paper, the comparison of various queue management algorithms is done based upon use of CPR and without CPR. Congestion Participation Rate (CPR) is novel metric approach proposed for the detection and prevention of LDDoS attacks. As LDDoS attacks does not decrease the number of sending packets when congestion occurs, but TCP does. We will check the effect of using various queue management algo- rithms on the various parameters of the flow of packets such as number of packets sent, received and lost etc. General Terms Comparison between normal TCP flow and LDDoS attack flow by using CPR approach using the three queuing man- agement algorithms named REM, RED, DROPTAIL, SFQ and FQ.
