Quality of Service Modeling and Analysis for Carrier Ethernet

PROEFSCHRIFT ter verkrijging van de graad van doctor aan de Universiteit Twente, op gezag van de rector magni…cus, prof. dr. Acknowledgements The journey to completing this PhD has not always been an easy one especially since I did it in combination with my work and family life. I would like to thank all those people who assisted and supported me in this e¤ort. Firstly, I would like to thank my promotors for guiding me through the research and having faith in my determination to complete the thesis. Michel, you helped and supervised me in spite of your move from Twente to Amsterdam and also during your stay at Stanford. Hans, I am glad you guided me more frequently. Your multiple thorough revisions of the thesis were very useful. Combining my PhD research with my job at Alcatel-Lucent would not have been possible without the support of my managers. I would like to thank Harold Teunis-sen, Paul Reinold and Michael Doubrava for supporting my ambition to complete this thesis. I would like to express my gratitude to NWO for funding the project, which assisted me in …nalizing my research and this dissertation. I am especially grateful to Nick den Hollander who was very helpful in …nding solutions during di¢ cult and uncertain times. Furthermore, I appreciate Boudewijn Haverkort's e¤orts for supporting this project at the University of Twente. I am also thankful to my fellow project members in the NOBEL, DAIDALOS and EQUANET projects. My (ex) colleagues at Alcatel-Lucent provided the stimulating environment for my research. Ronald, we have worked together on many Ethernet related topics and wrote several papers together. Your support with the simulation environment was especially useful. Arjan, discussions with you on the practical and standards related issues for Ethernet were very helpful. Maarten, I bene…ted from your experience with your PhD, which you did while working at Alcatel-Lucent. I want to thank you for your advice and willingness to answer any questions I had. I would also like to thank fellow colleagues from Alcatel-Lucent sales and product units. Discussions and interactions with them greatly contributed and shaped my understanding of Ethernet networks in general. Especially Gert Manhoudt, Michiel van Everdingen, Je¤ Towne and Stephan Roullot were always very open to the innovative ideas we proposed. I would also like to thank Sue Atkins, Dirk-Jaap Plas, Dennis Bijwaard, Ronald de Man and my Bell Labs Europe Hilversum colleagues. …
