【摘要】：下一代互联网已经成为发展的趋势，其中的应用服务种类也越来越多。为了给应用服务提供可靠的服务质量（QoS，Quality of Service）保障，QoS范畴的研究已经变得越来越重要。对于视频会议业务来说，其对带宽、抖动、延时等网络性能指标都十分敏感，因此QoS保障系统的提出能够使该业务更加流畅地运行，提供高可用的服务质量保障。 论文介绍了视频会议应用中的QoS保障相关技术，包括IP组播技术、基于测量的接纳控制方案、MOS评价标准以及各种通信协议等。根据调研结果以及视频会议应用的实际情况，提出了QoS保障系统的设计。系统的主要功能模块包括通信与消息解析、资源管理、网络测量以及会议监控和控制等。通信与消息解析模块是整个系统与外部系统进行数据交换的基础，，经过解析处理后的业务请求都会由会议控制模块实现视频会议相关的QoS保障业务逻辑，利用资源管理模块处理资源的分配，而网络测量模块则对网络环境进行实时的流量测量，视频会议的服务质量监控与评估在会议监控模块完成。 论文详细地阐述了QoS保障系统的总体设计以及每个功能模块的实现，通过结合视频会议系统的应用特点，提出了完整的服务质量保障方案。最后，论文给出了对整个QoS保障系统的主要功能和性能的测试与分析。根据测试结果显示，本文所提出的理论是符合实际情况的，而且设计方案也是具有可行性的。
[Abstract]:The next generation Internet has become the trend of development, and there are more and more kinds of application services. In order to provide reliable quality of service (QoS,Quality of Service) for application services, the research of QoS category has become more and more important. For video conference service, it is very sensitive to bandwidth, jitter, delay and other network performance indicators, so the proposed QoS guarantee system can make the service run more smoothly and provide high quality of service guarantee. This paper introduces the QoS security technologies in video conferencing applications, including IP multicast technology, metrological admission control scheme, MOS evaluation standards and various communication protocols. According to the research result and the actual situation of video conference application, the design of QoS guarantee system is put forward. The main function modules of the system include communication and message parsing, resource management, network measurement, conference monitoring and control, etc. The communication and message parsing module is the basis of the data exchange between the whole system and the external system. After analyzing and processing the business requests will be implemented by the conference control module to implement the QoS guarantee business logic related to the video conference. The resource management module is used to deal with the allocation of resources, while the network measurement module is used to measure the real-time traffic in the network environment. The quality of service monitoring and evaluation of video conference is completed in the conference monitoring module. In this paper, the overall design of QoS support system and the realization of each functional module are described in detail. By combining the application characteristics of video conference system, a complete scheme of quality of service assurance is put forward. Finally, the main function and performance of the whole QoS guarantee system are tested and analyzed. The test results show that the theory presented in this paper is in line with the actual situation and the design scheme is feasible.
