MOS协议分析及基于IP技术的语音编解码器选择
Analyzing of MOS and Codec Selection for Voice over IP Technology
摘要：
在本研究中，我们提出了一个架构解决方案，以实现在校园环境网络的IP语音（VoIP）服务。IP语音（VoIP）技术目前已成为一个讨论的问题。今天，在组织中部署这项技术确实可以比传统电话带来巨大的经济效益。因此，本研究将分析VoIP编解码器的选择，并调查平均意见得分（MOS）性能领域的演变与服务质量提供的软电话和IP电话。这项研究的重点是语音预测的质量，如i）MOS自动系统和人类感知之间的准确性和ii）不同类型的编解码器性能测量通过人类感知MOS技术。在本研究中，网路管理系统（NMS）是用来监测和捕捉VoIP在校园环境中的性能。另外，在校园环境中实现软电话和IP电话的最明显的问题是定义可用于操作环境的最佳编解码器选择。基于发现的结果，通过自动和手动系统的MOS测量能够预测和评估VoIP性能。此外，基于手动MOS测量，VoIP会话在局域网贡献更高的可靠性和可用性性能相比，广域网。
英文摘要：
In this research, we propose an architectural solution to implement the voice over IP (VoIP) service in campus environment network. Voice over IP (VoIP) technology has become a discussion issue for this time being. Today, the deployment of this technology on an organization truly can give a great financial benefit over traditional telephony. Therefore, this study is to analyze the VoIP Codec selection and investigate the Mean Opinion Score (MOS) performance areas evolved with the quality of service delivered by soft phone and IP phone. This study focuses on quality of voice prediction such as i) accuracy of MOS between automated system and human perception and ii) different types of codec performance measurement via human perception using MOS technique. In this study, network management system (NMS) is used to monitor and capture the performance of VoIP in campus environment. In addition, the most apparent of implementing soft phone and IP phone in campus environment is to define the best codec selection that can be used in operational environment. Based on the finding result, the MOS measurement through automated and manual system is able to predict and evaluate VoIP performance. In addition, based on manual MOS measurement, VoIP conversations over LAN contribute more reliability and availability performance compare to WAN.
