摘要: 该文提出了一种新的光突发装配技术,该技术由自适应门限突发装配算法和基于优先级的随机 化的偏移时间设置方案构成.该装配算法特别适合于多类别分组混合装配,能让所有类别的分组公平有效地使用装配能力,能较好地与IP层的QoS机制相匹配。计算机仿真结果表明该文提出的光突发装配技术在性能上具有一定优越性.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).
