A burst-length-based QoS scheme over OBS network

Optical Burst Switching (OBS) is considered as an efficient switching technique for building the next generation optical Internet. An offset-time-based scheme has recently been proposed in order to provide quality-of-service (QoS) in OBS networks. Unfortunately, the proposed service differentiation has several problems. In this paper, we propose a burst-length-based QoS scheme cooperate with Void-Filling, which is less complex and more valuable than existing offset-time-based scheme. Simulations are conducted to evaluate the performance of our burst-length-based scheme provisioning within OBS networks in terms of burst loss probability.
