    • 摘要: 现有异构网络传输控制协议不能准确估计网络状态,缺乏有效的丢包区分机制.为此,提出一种基于效用估计的丢包区分算法,并将其应用于多媒体业务TCP友好传输控制协议.该算法将网络状态估计算法和差异化丢包区分算法相结合,根据分组到达时间间隔估计当前网络的可用带宽,计算效用参数并估计网络状态,自适应地选取合理的区分机制,以准确区分无线-有线异构网络中拥塞/无线丢失,提升多媒体传输控制协议性能.实验部分比较了该算法与现有文献方法的仿真性能..

    • 摘要: 该文主要针对TC-TFRC中可容忍计时器固定设置所存在的缺陷,通过引入速率差来判断网络拥塞状况,并以此动态设置可容忍暂态计时器的计时时间。通过实验表明,在网络轻微拥塞时,改进的ETFRC策略能够以流媒体最低播放速率传输数据,在保证不引发更严重的网络拥塞的情况下,保证流媒体的正常播放;当网络发生严重拥塞时,ETFRC通过对网络现状的检测,在更短的时间内终止了低于流媒体最低播放速率的无效数据传输,避免造成个更大的网络拥塞,比TC-TRFC具有更好的TCP友好性。

    • 摘要: 针对TCP friendly rate control (TFRC)不能正确区分丢包原因,带宽利用率不高,网络状态变化响应迟钝的问题,本文提出了一个TFRC协议的改进算法TFRC BMN.该算法结合中间节点队列长度划分当前网络状态,由网络状态判断区分无线丢包与拥塞丢包,根据不同的丢包原因采取不同速率调节机制.此外该算法还引用积式增加积式减少(MIMD)的思想,当网络进入或退出拥塞状态时进行快速的响应.仿真实验结果表明,改进后的算法在高误码率的无线网络中性能有明显的改善与保持,同时提高了对网络拥塞变化的响应速度.%TCP friendly rate control (for short TFRC) can not differentiate the reason of packet losses, has low bandwidth utilization rate, and has slow reaction to the state change of network TFRC BMN. The algorithm is presented combineing the queue length of middle node to divided among the current network state, it differentiates the wireless packet losses from the congestion packet losses by the network state, and take different rate adjustment mechanism according to different lost package reason. In addition, because the thought of multiplicative increase multiplicative decrease (for short MIMD) is quoted, the algorithm can fast response when the network into or out of congestion state. Experiments show that the algorithm's performance are improved in wireless network, meanwhile response speed of network congestion is improved.

    • 摘要: A new adaptive layered multicast congestion scheme, ALM is proposed. ALM is a joint sender-receiver driven and router-assisted congestion control scheme. By combining the dynamic layering technique at sender and the adaptive rate control at receiver, ALM not only improves the adaptiveness and throughput, but also satisfies TCP-friendliness. The simulation results show ALM strategy can use network bandwidth effectively , and it also solves the problem of network bandwidth heterogeneity.Besides, it can calculate the TCP friendly rate at the receiver to achieve sharing the network resourceswith the TCP flow fairly.%提出了一种新的自适应分层多播拥塞控制方案(ALM).ALM是发送方与接收方共同驱动、由路由器辅助流量控制的拥塞控制方案,通过把发送方的动态分层和接收方的自适应速率调整有机结合,不仅增强了分层多播的适应能力,提高了系统的吞吐量,而且较好地满足了TCP友好性.仿真实验表明,ALM能有效地利用网络带宽,解决网络带宽的异构性问题,并能通过接收端计算TCP友好速率,使接收端达到与TCP流公平竞争网络资源的目的.

    • 摘要: Available bandwidth measurement methods which characterized as sending packet trains generate large probe traffic, as so to affect network performance. Three measurement patterns with different packet train length have been designed to simulate typical packet train sending policies, and the TCP-friendliness of available bandwidth measurement are analyzed by simulation. It finds that, the TCP-friendliness of available bandwidth measurement is not so well, as the probe streams increase the delay and packet loss of TCP streams, and trigger the congestion control mechanism. In simulation, it decreases 16% TCP transferred traffic; and larger or shorter packet trains have more influence on TCP performance. The analysis results in a typical available bandwidth measurement tool, Pathload, validated the conclusions, and also application policies of Pathload are concluded.%以发送包链为特征的可用带宽测量会产生较大探测流量而影响网络性能.设计了三种具有不同包链长度的测量模式模拟典型的包链发送策略,仿真分析了可用带宽测量的TCP友好性.发现可用带宽测量的TCP友好性并不理想,原因在于探测流会增大TCP流的时延及丢包而触发TCP的拥塞控制机制.仿真中最大降低TCP数据传输量近16%;且太长或过短的包链发送策略对TCP性能有更大影响.在Pathoad这一典型可用带宽测量工具中的分析结果进一步验证了该结论,且得出了Pathload的应用策略.

    • 摘要: Layered multicast is a promising solution to address the problem of multicast congestion control in heterogeneity network. However, schemes using this solution suffer from slow response time and lack of fairness, and induce a lot of loss by slow response and failed join experiments. In this paper we propose a new layered multicast based on delay-jitter trend (LM-DJT). LM-DJT introduces the delay-jitter trend model into an amended TCP throughput equation to estimate the TCP-friendly transmission rate, and each receiver adjusts its subscription layers according to the estimated transmission rate. Our simulation results show LM-DJT converges fast to the optimal layer of subscription, induces less loss to track the available bandwidth, and has inter-session fairness and TCP-friendliness.%针对多速率拥塞控制中存在的周期性丢包、拥塞响应速度缓慢等问题,提出基于延时抖动趋势的分层组播方案LM-DJT.该方案通过延时抖动趋势来推测当前网络状况,使接收端能够对网络拥塞进行早期检测,并将其引入到改进的TCP吞吐量公式中,用以估计当前传输路径的可用带宽,并据此进行相应的层次订阅调整.仿真实验表明LM-DJT能很好地适应网络环境的异构性,在保证带宽公平分配的情况下,具有较快的收敛和拥塞响应速度,引入较少的丢包.
