Abstract This paper proposes a new burst assembly technique for supporting QoS in Op tical Burst Switching (OBS) networks. It consists of the adaptive-threshold burst assembly algorithm and QoS-based random offset-time scheme. The algorithm fits well the multi-class burst assembly, and not only matches with IP QoS mechanism based on packet classifica tion, but also utilizes fairly and efficiently assembly capacity. The paper also provides the simulation for the performance improvement of the technique in Packet Loss Probability (PLP).
