QOS provisioning in optical burst-switched networks

QoS is an integral component of any networking system, particularly, with the current and future great diversity of the users´ applications and their manifold requirements. It is believed that the IP layer may not be the convergence layer with respect to QoS. In this paper a new QoS mechanism is introduced for Optical Burst Switching (OBS) networks that support Staged Reservation Scheme (SRS). For the new QoS mechanisms to be realizable and efficient in the optical burst-switched networks, the simplicity principle was one of the most important design considerations.
