OBS核心节点中FDL配置方式的研究

Research of FDL structure in OBS core node

摘要: 通过仿真,分析比较了在N×M交换节点中的分别采用共享式FDLs结构和非共享式FDLs结构的交换性能.结果表明,在负载为0.7、非共享式FDLs在级数大于24时,其丢包率小于10-6.而共享式FDLs在级数为24时,其丢包率大于0.1.非共享式FDLs的丢包率和平均时延水平都低于共享式的FDLs结构,交换性能更优异.

Abstract: In the N×M switching nodes,the performance of the share fiber delay lines(FDLs) is compared with that of the no-share FDLs.When the load is 0.7 and the stage number is 24,the packet destroy rate of the share FDLs is 0.1 and that of the no-share FDLs is 10-6.Which shows that the no-share FDLs are more efficient than the share FDLs.
