    Research in optical burst switching within the e-Photon/ONe network of excellence
    (Elsevier BV, 2007) Aracil, J.; Akar, N.; Bjornstad, S.; Casoni, M.; Christodoulopoulos, K.; Careglio, D.; Palacios, J. F.; Gauger, C.; Dios, O. G.; Hu, G.; Karasan, E.; Klinkowski, M.; Morato, D.; Nejabati, R.; Overby, H.; Raffaelli, C.; Simeonidou, D.; Stol, N.; Tossi-Beleffi, G.; Vlachos, K.
    This paper presents a summary of Optical Burst Switching (OBS) research within the VI framework program e-Photon/ONe network of excellence. The paper includes network aspects such as routing techniques, resilience and contention resolution, together with burst switch architectures. On the other hand, we also discuss traffic analysis issues, Quality of Service (QoS) schemes, TCP/IP over OBS and physical layer aspects for OBS.

    A survey of quality of service differentiation mechanisms for optical burst switching networks
    (Elsevier, 2009-09-26) Akar, N.; Karasan, E.; Vlachos, K. G.; Varvarigos, E. A.; Careglio, D.; Klinkowski, M.; Pareta, J. S.
    This paper presents an overview of Quality of Service (QoS) differentiation mechanisms proposed for Optical Burst Switching (OBS) networks. OBS has been proposed to couple the benefits of both circuit and packet switching for the "on demand" use of capacity in the future optical Internet. In such a case, QoS support imposes some important challenges before this technology is deployed. This paper takes a broader view on QoS, including QoS differentiation not only at the burst but also at the transport levels for OBS networks. A classification of existing QoS differentiation mechanisms for OBS is given and their efficiency and complexity are comparatively discussed. We provide numerical examples on how QoS differentiation with respect to burst loss rate and transport layer throughput can be achieved in OBS networks.
