A QoS-Oriented Protocol for Burst Admission Control in OBS Networks

Among the promising solutions for next generation Internet backbones, one can consider the optical burst switching (OBS) technology. One of the main aspects in the design of optical burst-switched networks is the development of a burst admission control protocol suitable for QoS provisioning. In this paper, we develop a method to address the call admission control (CAC) in OBS networks that is QoS-oriented. For this, an analytic model is developed for formulating the burst admission control problem. A QoS-constraints based burst admission control protocol is developed. Finally, simulation experiments are performed to validate the proposed schemes.
