摘　　要：研究了光突发交换网络中关键技术之一的突发组装机制,介绍了基于时间门限组装、基于长度门限组装和混合门限组装3种典型的突发组装机制,并对比分析了三种组装机制对网络汇聚性能(突发大小、组装时延)的影响以及自相似性能的改善情况,得出混合门限组装机制能获得更好的网络汇聚性能和自相似性能的改善的结论。This paper studies the burst assembly mechanism which is one of the OBS key technologies. The paper analyzes the three typical burst assembly mechanisms, including time-based threshold assembly, length-based threshold assembly, and mixed-threshold assembly. And it comparatively analyzes the influence of three assembly mechanisms on OBS network performance and the improvement of self-similar properties. The result shows that mixed assembly mechanism obtained the better network performance and self-similar performance improvement.
