Abstract

Abstract: The principle of DiffServ and the main elements affecting the voice quality of VoIP are analyzed.A method for evaluating the QoS for VoIP network——E-model is introduced.The performance of VoIP both on DiffServ and best-effort is compared by simulation.The quantitative assessment of the voice quality of VoIP is given by using E-model，and the user-level performance analysis for the VoIP on DiffServ is carried out.

Key words: DiffServ, Voice over Internet Protocol（VoIP）, simulation, E-model

摘要： 分析了区分服务的工作原理和影响VoIP语音质量的主要因素，介绍了一种语音质量的客观评价方法——E模型，运用ns-2仿真器构建网络仿真模型，比较VoIP在区分服务和传统网络中的性能表现，利用E模型对VoIP的性能进行了定量的客观评价，并为区分服务对VoIP的支持能力提供了用户级语音质量的分析。
