This dissertation was written as a part of the MSc in ICT Systems at the International Hellenic University. The basis of this project was to create a unique Traffic Generator. The main characteristic that differentiates it from other traffic generators is that it offers predefined realistic flows of packets that simulate certain traffic profile of applications. It can be used to evaluate the performance of a network and help during implemen-tation. It simulates five different real-time applications with prospect to insert additional ones. The anticipated outcome of this project is a tool that can be used from network administrators without complex configuration. I am extremely grateful to my supervisor, Dr Nick Savage, for giving me the oppor-tunity to work on this project and helped me with critical decisions during the study. I also acknowledge the valuable assistance of IHU Course office. Last but not least, I am grateful to my family for their support all these years.
