Acknowledgments
I would like to thank my supervisors, mr. Kostas Siozios and mr. Minas Dasygenis, for their
guidance and support throughout the whole process of creating this thesis.
I also want to thank Dimitris Tsiktsiris, for his thoughtful advice and help.
The IT department of AUTH, and especially mr. Georgios Pallas, for their help in gathering and
preparing the traffic from the university gateway, even though that part of the project failed
to launch in the end.
Lastly, I would like to express my gratitude to my family and friends, for the years of constant
support, help and encouragement that they generously provided me with throughout my
undergraduate and postgraduate studies, and for their patience while I was ranting about
things they didn’t understand.
This thesis was partially supported by the Hellenic Petroleum Company and the Special
