In this paper,the method for measuring the QoS for VoIP network is introduced and the main elements affecting VoIP QoS performance such as delay jitter,packet loss and IP network delay analyzed.
文章介绍了VoIP(IP网络上传送语音)语音质量的测试方法,分析了影响VoIP语音质量的主要因素:延迟、抖动、丢包率和时延。
In IP-based networks,VoIP has become the representative technology of the next generation voice system,but its QoS is limited by the IP network capacity.
在以IP为基础的网络中,IP网络上传送语音(VoIP)成为新一代语音系统的代表,但其业务质量因由IP网络承载而受到限制。
