Abstract: Optical burst switching (OBS) is an optical networking technology which consolidates the advantages of optical packet switching and optical circuit switching, while at the same time keeping away their limitations. Since OBS utilizes one –way reservation scheme, hence, due to contention bursts might be dropped at the intermediate nodes before they reach the destination. Hence, the burst dropping ratio is the critical performance estimation in OBS networks. The majority of the scheduling models in contemporary literature aimed to attain scheduling optimality are based on optimal utilization of their idle time. Not very many contributions endeavored to choose channels through any of the quality metric, and remarkably less contributions offer on wavelength allocation to lessen the burst drop ratio. In this regard, this manuscript endeavored to attain optimal wavelength allocation under divergent metrics that denoted as QoS metrics for dynamic scheduling through Void Filling and Burst Segmenting (QDS-VF).The proposed model is compared to the other contemporary model depicted in recent literature and found that burst loss ratio is lower in the proposed scheme.
