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。
Based on the coarse particle classification, a new optical burst assembly technology is proposed. It consists of two aspects: the mapping rule, which mainly solves the category grouping that a certain priority optical burst can be assembled and proposes three kinds of rules: S mapping, Q mapping and TQ mapping. The difference mainly lies in whether the mapping has self-adaptability. The dynamic The threshold assembly capability allocation scheme, ATQ DT, mainly solves the problem of how to allocate the optical burst assembly capability dynamically and reasonably. TQ mapping and ATQ DT automatically adjust mappings and assembly thresholds as Quality of Service (QoS) requirements and load conditions change. The simulation shows that their combination, “TQ mapping + ATQ DT” is most effective in guaranteeing the packet loss rate (PLP) of each packet type.
