Improving distributed traffic generation performance by using IMUNES network emulator

In this paper we present improvements of our software architecture for User Behaviour Based Network Traffic Generation (UrBBan-Gen). It consists of four modules Service repository, Control function and user interface, Behaviour process, and Traffic generation process. Improvements are performed on the traffic generation process, specifically on the virtualization section of UrBBaN-Gen through integration of the Distributed Internet Traffic Generator (D-ITG) which we use as a module for traffic generation with network simulator and emulator IMUNES. In this way we achieve two goals: 1) better scalability of the traffic generation and 2) possibility for testing of various network scenarios in simulated networks under realistic loads.
