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.

缓冲区大小对多媒体和突发流量竞争丢包的影响

这项工作分析了接入路由器缓冲区大小对丢包率的影响，以及它在出现突发流量时如何影响多媒体服务的 QoS。VoIP 流量、视频会议的真实痕迹和视频监控用于两种不同的中等链路利用率的场景。研究表明，某些应用程序的突发特性可能会损害语音呼叫的 MOS，尤其是在一定数量的突发重叠时。当链路利用率高于 70% 时，无法获得 VoIP QoS 的良好值。
