改进的长度自适应门限组装算法

Modifying the adaptive assembly algorithm based on the length threshold

在光突发交换中,针对自相似业务流,为了降低组装算法对分组阻塞率的影响,分析了Se-Yoon等人提出的长度自适应组装算法。根据自相似业务的突发特性,算法应及时更新算法参数,因此提出了一种改进算法,它更能降低业务流的自相似性,能更合理地根据到达的网络自相似业务流的特点自适应地调整长度门限值。仿真结果表明,改进后的算法分组阻塞率影响更小。

An adaptive assembly algorithm based on length thresholds in optical burst switching networks was put forward. It could reduce the self-similarity effectively and adjust the length thresholds adaptively according to the properties of the traffic stream. Moreover, it can obtain small packet blocking rate with the same scheduling algorithm.
