“…With the increasing bandwidth demand by applications such as high-definition television (HDTV) [1], grid computing [2] [3], and large scale scientific experiments (e.g., LOFAR project [4]), network providers are increasingly adopting hybrid network infrastructures that present higher capacity and more reliable data transmission. IP/optical hybrid networks are those that take data forwarding decisions simultaneously at both IP and optical levels [5].…”

Network measurement provides vital information on the health of managed networks. The collection of network information can be used for several reasons (e.g., accounting or security) depending on the purpose the collected data will be used for. At the University of Twente (UT), an automatic decision process for hybrid networks that relies on collected network information has been investigated. This approach, called selfmanagement of hybrid networks requires information retrieved from measuring processes in order to automatically decide on establishing/releasing lambda-connections for IP flows that are long in duration and big in volume (known as elephant flows). Nonetheless, the employed measurement technique can break the self-management decisions if the reported information does not accurately describe the actual behavior and characteristics of the observed flows. Within this context, this paper presents an investigation on the trustfulness of measurements performed using the popular NetFlow monitoring solution when elephant flows are especially observed. We primarily focus on the use of NetFlow with sampling in order to collect network information and investigate how reliable such information is for the selfmanagement processes. This is important because the selfmanagement approach decides which flows should be offloaded to the optical level based on the current state of the network and its running flows. We observe three specific flow metrics: octets, packets, and flow duration. Our analysis shows that NetFlow provides reliable information regarding octets and packets. On the other hand, the flow duration reported when sampling is employed tends to be shorter than the actual duration.

“…With the increasing bandwidth demand by applications, such as high-definition television (HDTV) [8], grid computing [151], and large-scale scientific experiments (e.g., LOFAR project [39]), the importance of hybrid optical and packet switching networks is growing. Network providers, such as SURFnet [146], GÉANT [63], amongst others, are increasingly adopting hybrid networks.…”

INCE this thesis is not the fruit of a single person, I would like to express my sincere gratitude to those who, somehow or other, helped me throughout all my Ph.D. years and made this thesis possible. First of all, I would like to thank to my supervisor, Dr. Ir. Aiko Pras, for his careful and patience guidance during all my study years. He gave me the opportunity to enroll as a Ph.D. student in the DACS group, which I am extremely grateful. I also would like to thank to Prof. Dr. Ir. Boudewijn R. Haverkort for his great advice and extreme professionalism. Not the least, I thank all DACS group members for having taken me and helped me during all these years. I would like to thank the members of my graduation committee: Prof. dr. Lisandro Z. Granville, Dr. hab. Olivier Festor, Prof. dr. ir. Cees Th.A.M. de Laat, Prof. dr. Antonio Liotta, Prof. dr. ing. Paul J.M. Havinga, and Prof. dr. Hans van den Berg. I am really grateful for your time spent reviewing this thesis. Special thanks to Lisandro for his valuable help during the third year of my Ph.D. trajectory. The flow analysis performed in this thesis would not have been possible without the cooperation of SURFnet, GÉANT, and the ICTS department of the University of Twente. Special thanks to Hans Trompert (SURFnet), Maurizio Molina (GÉANT), and Roel Hoek (ICTS) for their helpful contribution in the flow collection process. Last, but by no means least, I also thank my colleagues of the EMANICS project by their valuable collaboration. I also extend my gratitude to all my friends who made my staying here in Enschede more enjoyable. Coffee breaks, parties in Macandra, Grolsch tours, social events, dinners or simply "een biertje in de stad", all these events would not be as much fun without you. With this respect, I would like to particularly mention
