本文提出了一种用于VoIP网络的QoS管理架构。通过使用一种客观的语音质量评估工具对定期生成的携带人工语音信号的测试呼叫进行持续自动监测语音质量，特别是MOS（平均意见得分）。基于端到端测量的准入控制用于在各种流量条件下将双向语音流的丢包率保持在预定值以下。给出了一种网络设计方法以满足目标阻塞概率和丢包率。通过仿真评估具有基于端到端测量的准入控制的网络的阻塞概率和丢包率等网络性能。结果表明，准入控制在各种网络条件下都能很好地控制丢包率。
This paper presents a QoS management architecture for VoIP networks. Voice quality, specifically MOS (mean opinion score), is continuously and automatically monitored by using an objective voice quality evaluation tool for periodically generated test calls carrying artificial voice signals. Edge-to-edge measurement based admission control is used to maintain packet loss rates for both directional voice flows below a predetermined value under various traffic conditions. A network design method is given to meet target blocking probability and packet loss rate. Simulation is used to evaluate network performance such as blocking probabilities and packet loss rates for the network with edge-to-edge measurement based admission control. It is shown that admission control works well to control packet loss rate under various network conditions.
