| 摘 要： | 从如何提高基于SIP协议的VoIP系统的语音质量出发，分析了该系统与MPLS技术结合处的难点，并提出了一种支持QoS的SIP代理服务器模型的解决方案。该方案的设计结构清晰、可扩展性强，解决了SIP代理服务器在IP网络中没有会话服务质量控制能力的问题，是一种好的融合VoIP及MPLS两大技术的应用模型。该方案目前已运用于基于嵌入式Linux平台的VoIP系统中，完全能够满足高质量语音的需求。

| Abstract: | This paper depicts how to improve the voice quality of VoIP system based on SIP protocol, and then analyses the difficulty in combining this VoIP system with MPLS technology. And it presents a design model and implementation of SIP proxy server for QoS required network. This model has good expansibility and a clear framework, and gives a solution to the problem that SIP Proxy server without any QoS abilities. It is a nice application-model merges MPLS technology into VoIP system. This solution is already adopted in the VoIP system under embedded Linux platform and it mceets the requirement of high quality of voice communication well. |
