摘　　要：提出了一种光突发交换网中基于自适应门限的改进型突发组装算法,并且对改进算法进行了仿真研究。研究结果表明,改进算法生成的突发包大小均匀,能够显著地抑制突发包包长的变化;并且该算法能够降低流量的自相似性,改善流量的性能,通过与以往同类的典型算法比较,可以看出该算法能更有效地实现流量整形,因而有利于进一步提高OBS网络的性能。Proposed in this paper is an improved adaptive burst assembly algorithm. Simulations are conducted to validate out algorithm. The simulation results show that the improved algorithm can decrease the similarity of the output traffic more efficiently than the Max-Time-Max-Length assembly algorithm does. The burst length created by improved algorithm changes less than that of the unimproved assembly algorithm. These all can enhance the performance of the OBS networks. The studies also show that the delay of assembled packets is changed with the degree of the similarity.
