Implementation of SYN Flood Attack Simulator in NS-3

Abstract

The paper presents an implementation of support for simulation of SYN Flood DDoS attacks in NS-3 simulator. The software architecture of NS-3 is outlined, as well as code changes that were made. The unbalanced dumbbell topology is used in simulation. The simulated DDoS attacks are presented visually using diagram of Shannon entropy time series, calculated on distribution of destination ports and addresses. The implementation enables researchers to study methods for detection and mitigation of SYN Flood attacks using NS-3 simulator.
