Abstract
In Optical Burst Switching(OBS) networks, burst loss due to contention significantly affects the performance of networks. Even if many contention resolution schemes have been proposed, most of them have focused mainly on passively resolving contentions instead of avoiding them. In this paper, we propose an active contention avoidance scheme which controls a burst sending rate according to traffic load and burst loss in a network. Simulation results show that the proposed scheme can more effectively reduce the burst loss rate compared to existing OBS model with and without burst sending rate control, and at the same time guarantees throughput.
