An enhanced burst assembly scheme over optical burst switching networks
International Journal of Information and Communication Technology, 2017Recently, real-time traffic occupied a large portion of the internet's traffic, which has strict quality of service (QoS) requirements in terms of delay. Thus, guaranteeing the network end-to-end delay is one of the main important factors to guarantee the QoS for the real time traffic over the internet.

Performance evaluation of optical burst switching with assembled burst traffic input
Global Telecommunications Conference, 2002. GLOBECOM '02. IEEE, 2003This paper studies loss performance of optical burst switching (OBS) with assembled burst traffic input by exploring the characteristics of assembled burst traffic. We analyze the smoothing effect of assembly algorithms, which changes the statistical properties of packet flows, and and that assembly algorithms smooth the short range burstiness in ...

The Effect of Burst Assembly on Performance of Optical Burst Switched Networks
2004We evaluate and compare the performance of timer-based and threshold-based assembly algorithms in Optical Burst Switching networks. Results including burst blocking probability, mean packet delay and link utilization at the ingress node are presented from both simulations and two theoretical models.

Effect of burst assembly on synchronization of TCP flows
2007 Fourth International Conference on Broadband Communications, Networks and Systems (BROADNETS '07), 2007Synchronization of multiple TCP flows in optical burst switched networks is considered in this paper. TCP flow synchronization happens when concurrent flows accessing the optical network at the same edge node increase/decrease their congestion windows at the same time intervals, thus causing a significant instability of data transmission rate ...

Sliding window-based Burst Assembly Method in Optical Burst Switching Networks
2006 14th IEEE International Conference on Networks, 2006Burst assembly at edge nodes is an important issue for the optical burst switching (OBS) networks because it affects the traffic characteristics and has an influence on the burst loss performance. By applying the fractional Brownian motion (FBM) model, we find that the timer-based and threshold-based assembly algorithms could not avoid increasing the ...

An optical burst reordering model for a time-based burst assembly scheme
2008 5th International Conference on Broadband Communications, Networks and Systems, 2008In optical burst switching networks, contention resolution schemes as well as contention avoidance schemes reduce the burst loss probability. These schemes delay the burst delivery and may change the burst arrival sequence. In this paper we present an analytic burst reordering model and derive analytically the impact of a time-based burst assembly ...

A Low-Latency Burst Assembly Technique in Optical Burst Switching Networks
2006 International Conference on Communications, Circuits and Systems, 2006Optical Burst Switching (OBS) is a promising paradigm for the next generation internet. Burst assemble mechanism is one of the key issues in OBS networks. In this paper, a burst assemble mechanism based on burst-length-prediction is proposed. The edge nodes measure the coming packet streams within the pre-defined period for measure, and predict the ...

A novel burst assembly method for energy saving in burst switching networks
TENCON 2012 IEEE Region 10 Conference, 2012Future growth of the Internet is likely to be constrained by its own energy consumption. As shown in recent studies, by adopting burst switching technologies, energy consumption of the core network could be reduced. In this study we first analyse the relationship between burst size, arrival rate, and energy consumption of a core router port in a burst ...

An Intelligent Segmented Burst Assembly Mechanism in Optical Burst Switching Networks
Chinese Physics Letters, 2008We focus on the burst assembly mechanism and propose a new intelligent method in which the burst is assembled from several internet protocol (IP) packets in which the number of IP packets is changed according to the traffic load and the burst is segmented into several parts, called the ISOBS mechanism.

A study of adaptive burst assembly mechanism in optical burst switch networks
SPIE Proceedings, 2004As a promising switching paradigm, Optical Burst Switch (OBS) was proposed for optical networks showing more efficient and shorter delay than traditional circuit switching, and it is more feasible than optical packet switching. In OBS, burst assembly is one of the critical technologies, and will significantly affect the performance of networks. In this
