一种基于资源动态分配的光突发装配新技术(英文)
A Novel Optical Burst Assembly Technique Based on Dynamic Resource Allocation
【摘要】 在粗颗粒分类基础上提出了一种新的光突发装配技术。它包括两个方面 :映射规则 ,主要解决某一优先级光突发可以装配的类别分组 ,提出了S映射、Q映射和TQ映射 3种规则 ,其差别主要在于映射是否具有自适应性 ;动态门限装配能力分配方案 ,即ATQ DT ,主要解决如何动态、合理地分配光突发装配能力。TQ映射和ATQ DT可随服务质量 (QoS)要求和负载情况的变化而自动调整映射关系和装配门限。经仿真表明 :它们的组合 ,即“TQ映射 +ATQ DT”在保证各分组类别的分组损失率 (PLP)上效果最为明显。
【Abstract】 WT5”FZ]:A novel optical burst assembly technique proposed,based on map rules and a dynamic threshold mechanism called ATQ DT.How to map the IP quality of service(QoS) to burst priority was resolved by the map rules,and how to efficiently allocate assembly capacity among classes belonging to the same priority was answered by ATQ DT,which determines the maximum share for each class.Simulation results show ATQ DT with TQ map can most remarkably improve the packets loss probability (PLP) to support QoS.
【Key words】 dynamic threshold; burst assembly; map; optical burst switching(OBS); quality of service(QoS);
