The fewer queue managers that input and output messages have to traverse the cheaper the cost of processing the messages and therefore the higher the message rate that can be obtained. 输入输出消息需要遍历的队列管理器越少,处理消息的成本就越低,由此可获取更快的消息速度。
The model is then linearized to derive a small signal model between the packet marking probability and the bottleneck router queue length as the input and output of the TCP Vegas / AQM system. 通过对该模型进行线性化处理,得到以丢包率为输入、瓶颈路由器队列长度为输出信息的TCPVEGAS/AQM系统的小信号模型。
We first consider the M / M / s queueing model with two priorities. Through the analysis of state transition-rate equations of two priorities, the average queue length at the input or output of communications systems is derived. 首先考虑带有两个优先权的M/M/s排队模型,通过对两个队列的状态转移方程的分析,给出了通信系统输入输出线上的稳态队长。
Finally, according to the implementation requirement of QoS in the terabit router, we present a two-stage QoS scheduling architecture including the VOQ queue management based on output ports in the input side and priority based queue in the output side. 最后通过T比特路由器QoS实现的需求,提出了输入侧基于输出端口VOQ排队和输出侧基于优先级排队的两级调度QoS实现结构,并给出了该结构下T比特高性能路由器的QoS实现方案。
Considering the character of the traffic flow in the queue upstream of the bottleneck, this paper improves the conventional cumulative arrival and departure model, and forms the new traffic flow model, which is named I / O model ( input / output model ). 文章基于交通瓶颈路段车辆排队状态的实际变化特征,对传统的累计到达-消散模型(cumulativearrivalanddeparturemodel)进行了修正,构造了改进的累计到达-消散模型(即I/O模型)。
