摘要
阐述了可以弥补光电路交换和光突发交换二者缺点的混合交换技术,提出了一种采用混合交换技术的新型光交换网络,分析了该新型网络中的流量特性并提出了与该网络相应的传输机制。实验表明,采用该传输机制的新型光交换网络,在源负载低于0.75的情况下,其网络丢包率和吞吐量等性能均优于普通混合交换网络,能达到优化网络资源的目的。
The hybrid switching technology which combined optical circuit switching and optical burst switching is described.The characterization of internet protocol traffic is studied in OBS network.A new hybrid switching architecture and a constrained assembly scheme are proposed.Simulation shows that when traffic load is less than 0.75,the new optical switching net with the assembly scheme can gain higher performance than the normal one,especially in total drop rate and throughput,which can further optimize the resource.
