Abstract: Wavelength division multiplexed (WDM) optical burst switching (OBS) is a promising technology for realizing next generation high speed backbone transport networks. With the increasing use of the Internet to support the transport of different traffic types, including that of real-time applications, supporting quality-of-service (QoS) in the optical core network is becoming important. This research focuses on QoS provisioning in WDM OBS networks in terms of service differentiation and fairness. All the proposed methods stress upon the importance of relieving the core nodes from heavy computation burden and from depending on the use of buffer. Firstly, we develop fast and efficient burst rescheduling techniques and algorithms supporting service differentiation and fairness. Next, we propose an efficient fairness improvement method which ensures that ingress-egress node pairs of different path lengths perform almost equally. Finally, we develop an efficient edge-to-edge proportional QoS provisioning method. The performances of all the proposed methods are evaluated through simulation experiments.
