【摘要】：随着Internet技术和网络带宽的进一步发展,各种因特网业务,如：网络购物、微博、在线视频等已经成为人们生活娱乐的一部分。与传统的网页浏览等业务相比新兴的因特网业务具有很高的实时性,所以需要更高的网络带宽,更小的网络时延和抖动。并且目前基于TCP/IP的互联网所提供的是一种“尽力而为”的服务,在传输质量方面并没有保障机制,特别是网络带宽,丢包率,时延等经常变化,很不稳定。因此对因特网业务质量进行监测与评估具有重要意义。本文首先从因特网质量监测系统出发,对整个系统的结构与功能进行了介绍,紧接着介绍了因特网业务质量监测相关应用层与传输层协议,然后归纳和总结了因特网业务质量监测的相关指标。在论文接下来的部分中主要对因特网业务质量监测与评估的关键问题进行了研究。首先对因特网业务质量监测系统中的视频业务质量监测模块进行研究,主要介绍了视频业务监测模块已经实现的功能,并且详细阐述了视频业务质量监测模块需要优化和改进的功能以及这些功能的具体实现。使得优化和改进后的视频质量监测模块支持对主流视频网站的主要视频格式的质量监测。接着对路由出口监测业务进行研究,详细说明了路由出口监测业务的研究意义以及路由出口监测模块监测点以及服务器端的详细实现。同时对该系统得出的可疑路由结果进行分析,验证系统的正确性。本文最后对因特网业务质量主观综合评估进行研究,提出了一个业务质量主观综合评估模型,对因特网业务质量监测系统监测到的业务提取出关键指标并进行质量综合评估,从而来反映用户体验。
[Abstract]:With the further development of Internet technology and network bandwidth, various Internet services, such as Internet shopping, Weibo, Online video has become a part of people's life and entertainment. Compared with traditional web browsing and other services, the new Internet services have high real-time performance, so they need higher network bandwidth. At present, the Internet based on TCP/IP provides a kind of "best effort" service, and there is no guarantee mechanism in terms of transmission quality, especially network bandwidth, packet loss rate, delay and so on. It is very unstable. Therefore, it is important to monitor and evaluate the quality of Internet services. This paper first introduces the structure and function of the whole system from the perspective of the Internet quality monitoring system, and then introduces the application layer and transport layer protocol related to the quality monitoring of Internet services. Then the related indexes of Internet service quality monitoring are summarized and the key issues of Internet service quality monitoring and evaluation are studied in the following part of this paper. Firstly, the video service quality monitoring module in the Internet service quality monitoring system is studied, and the functions of the video service monitoring module are mainly introduced. The functions of the video service quality monitoring module needed to be optimized and improved and the realization of these functions are described in detail. The optimized and improved video quality monitoring module supports the main video of the mainstream video website. Quality monitoring of format. Then, the research on the route exit monitoring service is carried out. The research significance of routing exit monitoring service and the detailed implementation of monitoring points of routing exit monitoring module as well as the server side are described in detail. Meanwhile, the suspicious routing results obtained by the system are analyzed to verify the correctness of the system. In the end of this paper, the subjective comprehensive evaluation of Internet service quality is studied, and a subjective comprehensive evaluation model of service quality is proposed, which extracts the key indexes and evaluates the quality of the services monitored by the Internet Service quality Monitoring system. To reflect the user experience.
