论文摘要
这项工作介绍了访问路由器缓冲区大小对数据包损耗率的影响，以及在存在爆发流量时如何影响多媒体服务的QoS。 VoIP流量，Viedoccontrencing和Videosurvellance的真实痕迹在具有中等链接利用的两种不同方案中使用。研究表明，某些应用的爆发性质可能会损害语音调用，尤其是当一定数量的爆发重叠时。当链接利用率高于70％的VoIP QoS值时，无法获得。
This work presents an analysis of the effect of the access router buffer size on packet loss rate and how it can affect the QoS of multimedia services when bursty traffic is present. VoIP traffic, real traces of viedoconferencing and videosurvellance are used in two different scenarios with medium link utilization. The study shows that the bursty nature of some applications may impair the MOS of voice calls especially when a certain number of bursts overlap. When link utilization is above 70% good values of VoIP QoS cannot be obtained.
