摘要
给出了固定长度、固定时间和混合汇聚三种典型的光突发交换网(OBS)汇聚算法在NS-2中的实现,并以一个8节点OBS网络为平台,将三种汇聚算法下网络的突发包端到端时延和网络拥塞率进行比较。最后,对仿真结果进行了分析和讨论。
Realization of three typical OBS（Optical Burst Switching） assembly algorithms, the FAP（Fixed Assembly Period）, FAS（Fixed Assembly Size） and hybrid algorithms, are presented in this paper. On the basis of detailed description of three assembly algorithms, an 8 nodes OBS simulate network is taken as an example to compare the different performance with blocking probability and delay of the assembly burst packets. Finally, the simulation results is discussed and analyzed.
