One of the main challengers of the future Internet is to ensure QoS for various types of traffic characteristics with differentiated service requirements. It has been highlighted that OBS can provide high bandwidth data transmission in alloptical Internet network. However, the provisioning of QoS in OBS network is still an issue. The focused of this study is to develop QoS provisioning mechanism at the ingress and core node of OBS network. The proposed QoS provisioning ensures that the differentiated traffic is able to achieve their respective demands. This study proposed a DiffServ-aware ingress node with priority queueing (PQ) and burst assembly mechanisms. In addition, a core node with contention resolution scheme using FDL_WA_WPremp is developed as part of the integration of the proposed OBS network.
