摘要
光突发交换(OBS)被认为是下一代光纤通信网络的典型代表。文章研究了在OBS核心节点中突发数据包由于竞争相同的输出数据信道而发生的冲突问题,对冲突时的网络性能进行了分析,得出了在不同网络负荷情况下的包丢失率情况,研究结果对OBS网络的实际建设有一定的理论指导意义。
Optical Burst Switching （OBS） is regarded as one of the representative technologies for the next generation fiber-optic communication networks. In this paper, the contention issue arising from data bursts contending for the same output data chan- nel in the OBS core node is studied, the network performances in the contention analyzed and the packet loss probabilities under different network traffics obtained. The results of the study have certain theoretical guiding significance to the construction of OBS networks.
