| 摘 要： | CIOQ交换结构通常在输入端口侧采用基于VOQ结构的输入排队，为了实现VOQ队列报文的优先级区分丢弃，文章在实验的基础上给出了一种支持DiffServ结构中QoS的多门限随机早期丢弃（MTRED）队列管理机制。并通过大规模业务流量下的仿真对不同丢包门限的设置进行了深入的研究，最后给出了相关结论。

| Abstract: | The CIOQ switch architecture often uses the VOQs at the input ports to obtain 100% throughput. In order to provide differentiated QoS services to packets destined to each VOQ, a multi-threshold random early detection active queue management is proposed. The scheme is studied under large scale Internet traffic simulation with NS, and how the different threshold settings can affect the packets loss ratio and delay performance is concluded at the end of this paper. |
