A burst assembly algorithm for traffic smoothing in high speed networks

In this paper is addressed the issue how to provide QoS control and improve performance in high speed Optical Burst Switching (OBS) networks. In order to provide better proportional differentiated services is proposed a novel burst assembly algorithm (named adaptive timer-based) with traffic shaping functions to reduce the variance of assembled traffic and improve the burst loss performance. Next is presented a precise analytical model to study the performance of the assembled traffic in high speed networks. The simulation results show that the adaptive timer-based assembly algorithm has better performance in terms of edge buffering delay and can lighten burst loss ratio for TCP flows of the OBS network.
