Optical Burst Switching (OBS) has been developed as an efficient switching technique for the next generation optical Internet. A critical issue for OBS networks is the burst loss which could occur due to contention and/or insufficient offset time. Burst Loss Ratio (BLR) is used as the main performance parameter in bufferless OBS networks. This paper proposes a new TCP statistics based method to predict...
Optical Burst Switching (OBS) has been developed as an efficient switching technique for the next generation optical Internet. A critical issue in OBS is the burst loss which could occur due to contention and/or insufficient offset time. Burst Loss Ratio (BLR) is used as the main performance parameter in OBS networks. In this paper, we investigate the assignment of the offset time and its effect on...
Burst contention is a well-known challenging problem in optical burst switching (OBS) networks. Deflection routing is used to resolve contention. Burst retransmission is used to reduce the burst loss ratio (BLR) by retransmitting dropped bursts. Previous works show that combining deflection and retransmission outperforms both pure deflection and pure retransmission approaches. This paper proposes...

This paper considers the use of closed loop feedback control theoretic techniques to improve the performance of optical burst switching (OBS) networks. In OBS networks, the burst loss ratio (BLR) is the ratio between the lost bursts to the sent bursts. The BLR is used as a performance metric. The desired burst loss ratio depends on the application using the network. Burstification rate is the rate...
This paper applies the use of control-theoretic techniques and feedback consisting of current system behaviour to implement policies such that threshold values specified in the policies are optimized. The proposed approach in this paper is compared to other dynamic feedback control approaches. Results show that the proposed approach outperforms the other dynamic feedback control approaches. It managed...
One challenge associated with developing autonomic systems is that the system has multiple elements that should be autonomic but must also interoperate with each other. This paper addresses this problem within the context of dynamic resource allocation within a data center based on control-theoretic techniques.
