Performance Analysis of RED & Robust RED
Arsh Arora, Lekha Rani Bhambhu · 2014
Active Queue Management is a way to control Congestion. The existing RED (Random Early Detection) Active Queue Management algorithm and its variants are found vulnerable to emerging LDoS attacks. The RRED algorithm was proposed to improve TCP throughput under LDoS attacks by detecting and filtering out attack packet. We conduct a set of simulation to compare and evaluate the performance of RED and RRED under normal TCP traffic without LDoS attacks and With LDoS attacks. The results show that, RRED algorithm nearly fully preserves the TCP throughput in the presence of LDoS attacks. Simulation is done by using Network Simulator (NS2)
