| 摘 要： | 设计了一个用于光突发交换网络边缘节点中的汇聚模块(OBS-Ethernet自适应汇聚模块)。OBS-Ethernet自适应汇聚模块引入了流量检测队列,并通过该队列的检测结果选择合适的时间汇聚门限。同时,OBS-Ethernet自适应汇聚模块还通过BDP包长的反馈信息来修正控制曲线。仿真结果表示:与MBMAP汇聚模块相比,OBS-Ethernet自适应汇聚模块在网络数据突发性较强的情况下,具有更小的平均汇聚时延。并且与前者采用两个固定的汇聚门限不同,OBS-Ethernet自适应汇聚模块的时间汇聚门限能够随着网络流量的变化而自适应地调整。

| Abstract: | An assembly module entitled OBS-Ethernet self-tuning assembly module was designed for the edge node in optical burst switching networks.The traffic detection queue was introduced in the designed module by whose output was used to choose the suitable assembly time threshold.Moreover,the control curve was also adjusted by the feedback of the BDP length.Simulation results show that the OBS-Ethernet self-tuning assembly module has less average assembly delay if the traffic bursty is strong when compared with MB... |
