The simulation results show that this controller constrains the oscillation of acr and the queue length of switch . in some degree , the performances of steady and instantaneous state have been improved 线性pid控制器在一定程度上抑制了系统振荡,使得系统的稳态/动态性能有所改善,同时使得系统具有一定的鲁棒性。
Moreover , mean queue length expressions of asymmetric system are obtained explicitly via iterative algorithm on the first moments of the system , and simulation results demonstrate effectiveness of analysis 通过对系统一阶特性的迭代计算,最终解析出非对称情形下的平均排队队长表达式,并且利用计算器仿真实验证明了分析的有效性。
The method adopted the self - discarding packet technique that was a means of determining transfer by comparing the queue length of the transiting router with a specified queue value on the packet 该方法采用数据包丢失技术,通过比较传送的数据报文中的特殊队列值和所经过的路由器中数据包的排队队列长度值来决定是否对当前数据报文丢弃。
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。
The third chapter deals with a non - absolute priority queueing system b / d / 1 with decision time and two priority . this is a discrete time system . also adopting the method of imbedded markov chain , we can obtain the mean queue length for each queue 采用嵌入马尔可夫链的方法,求出了两个队队长联合分布的母函数的解析表达式,并进而求出了两个队的平均队长。
However , with many burst traffic simultaneously arriving at a node , the queue length may become larger and buffer overflow in a moment , or high - speed link is emerged into slower one , there will be in congestion 然而,当多个突发业务同时到达一个节点时,缓存队列长度迅速增加,在极短的时间内出现缓冲溢出,或高速链路接入慢速网络中引起输入链路速率大于输出链路速率,则导致网络拥塞。
Although the simplicity of binary flow control is very attractive , the queue length and allowed cell rate ( acr ) controlled by the standard efci algorithm oscillate with great amplitude , which must have negative impact on the performance , so its applicability was doubted 尽管二进制abr流量控制的简洁性具有相当的吸引力,但标准的efci算法控制的队列长度和允许信元速率( acr )却易出现大幅振荡的现象,这势必会降低链路的利用率,严重影响交换机的性能。
In addition , considering traffic security , operational efficiency and people ' s travel habits , the setting of signal phases must satisfy strong constraints , such as maximum and minimum green time , maximum queue length and smooth switch of signal timing parameters 并且,从交通安全、通行效率及人们出行习惯的角度考虑,信号灯相位的设置具有很强的约束,如最短和最长绿灯持续时间、最大排队长度以及信号灯的配时参数要具有一定的稳定性不能变化太剧烈等等。
It is found ecn could n ' t solve the problem that the sender responds to congestion slowly , and the average queue length of router is sensitive to the static parameters of ecn . in chapter four we propose an algorithm called fecn , which provides congestion control and indication messages in router , so that the sender could response to congestion in good time . this algorithm can also adjust the max drop probability according to the active conne Ik的特性,而且平均队列长度和网络吞吐量对ecn的静态参数较为敏感,因此本文在第4章中提出了一种fecn算法,该算法在路山器处提供拥塞控制和指示机制,使源端能够快速响应路由器发回的拥塞指示消息,调整发送速率,避兔拥塞的发生,该算法还可以通过估计链路中的活动连接数动态调整最大丢弃概率。
City intersection is the joint of road network , which plays an important role in road capacity and service . it is very important and valuable that we should try our best to manage city intersection traffic control and dig deeply current traffic resource so as to improve intersection capacity and debase delays and queue length . the paper does a little work on the study field for promoting designing and controlling civil intersection intelligently and integratively 解决好城市交叉口的交通控制管理,挖掘现有交通资源的潜力,提高交叉口通行能力,减少在交叉口处的停车与延误,是一项利国利民的重要研究工作,本文在这方面做了一些探讨,望能为早日实现我国交叉口设计、控制、管理的智能化、集成化和专家知识系统库尽一份力量。
