Among the promising solutions for next generation Internet backbone, one can consider optical burst switching (OBS) technology. This technology does not, however, provide suitable quality-of-service (QoS) support. Several schemes have been proposed to provide QoS differentiation in OBS networks. The majority of these schemes are based on a relative QoS model in which the performance of a given traffic class is defined in comparison with other classes. A set of mechanisms have been proposed to provide an absolute traffic loss guarantee, but no mechanism has been proposed to handle absolute transmission delay in OBS networks. The aim of this paper is to propose a solution to provide an absolute transmission delay guarantee over an OBS network and thus support emerging multimedia applications with delay and bandwidth constraints based on a network architecture that is suitable for OBS switching and QoS provisioning. We also develop an analytic model based on a queuing system of the proposed solution. Finally, simulation experiments are conducted to validate the proposed scheme and study its features.
