【摘要】：下一代互聯網已經成為發(fā)展的趨勢，其中的應用服務種類也越來越多。為了給應用服務提供可靠的服務質量（QoS，Quality of Service）保障，QoS范疇的研究已經變得越來越重要。對于視頻會議業(yè)務來說，其對帶寬、抖動、延時等網絡性能指標都十分敏感，因此QoS保障系統(tǒng)的提出能夠使該業(yè)務更加流暢地運行，提供高可用的服務質量保障。 論文介紹了視頻會議應用中的QoS保障相關技術，包括IP組播技術、基于測量的接納控制方案、MOS評價標準以及各種通信協(xié)議等。根據調研結果以及視頻會議應用的實際情況，提出了QoS保障系統(tǒng)的設計。系統(tǒng)的主要功能模塊包括通信與消息解析、資源管理、網絡測量以及會議監(jiān)控和控制等。通信與消息解析模塊是整個系統(tǒng)與外部系統(tǒng)進行數據交換的基礎，，經過解析處理后的業(yè)務請求都會由會議控制模塊實現視頻會議相關的QoS保障業(yè)務邏輯，利用資源管理模塊處理資源的分配，而網絡測量模塊則對網絡環(huán)境進行實時的流量測量，視頻會議的服務質量監(jiān)控與評估在會議監(jiān)控模塊完成。 論文詳細地闡述了QoS保障系統(tǒng)的總體設計以及每個功能模塊的實現，通過結合視頻會議系統(tǒng)的應用特點，提出了完整的服務質量保障方案。最后，論文給出了對整個QoS保障系統(tǒng)的主要功能和性能的測試與分析。根據測試結果顯示，本文所提出的理論是符合實際情況的，而且設計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.
