Abstract

Optical burst switching (OBS) technology is a promising solution for the next generation Internet backbone. However, call admission control (CAC) and QoS support constitute critical issues for this technology. In this paper, we propose a novel QoS-Oriented scheme for burst admission control in OBS networks. An analytic model is developed to estimate the provided QoS for a given traffic type. We also develop a performance evaluation study to validate the proposed scheme and evaluate its impacts on the efficiency of network resource utilization.
