OBS Network Resource Dimensioning: A QoS-based Approach

Among the promising solutions for next generation Internet backbones, one can consider the optical burst switching (OBS) technology. The deployment of the OBS technology needs to address dimensioning and resources optimization issues that constitute an essential task in the development of OBS services. In this paper, we propose a QoS-based approach to address these issues in the development of OBS networks. An analytic model is developed for network resources dimensioning and optimization problems´ formulation. A simulation model is developed to validate the proposed approach, and to study the impacts of some key input system parameters on the optimal network configuration.
