Optical burst switching networks

Research and improve scheduling admission control mechanism to enhance QoS based on incoming burst rate prediction at core node to improve scheduling efficiency for low QoS bursts but still ensure a level of service quality for high QoS bursts. The effectiveness of the scheduling admission control mechanism was valued through simulation and mathematical analysis.
