This paper presents the QoS differentiated Adaptive Scheduled Optical Burst Switching (QAS-OBS) paradigm that efficiently supports dynamic grid applications. (QAS-OBS) paradigm enables differentiated-services optical burst switching via two-way reservation and adaptive QoS control in distribute wavelength-routed networks. Based on the network loading status, the edge nodes dynamically optimize per-class lightpath reservation control to provide proportional QoS differentiation, while maximizing the overall network throughput. Unlike existing QoS control schemes that require special core network to support burst switching and QoS control, QAS-OBS pushes all the complexity of burst switching and QoS control to the edge nodes, so that the core network design is maximally simplified. Simulation results evaluate the performance of QAS-OBS and verified the proposed control schemes could provide proportional QoS control while maximizing the overall network throughput.
