【摘要】：隨著Internet技術和網絡帶寬的進一步發(fā)展,各種因特網業(yè)務,如：網絡購物、微博、在線視頻等已經成為人們生活娛樂的一部分。與傳統的網頁瀏覽等業(yè)務相比新興的因特網業(yè)務具有很高的實時性,所以需要更高的網絡帶寬,更小的網絡時延和抖動。并且目前基于TCP/IP的互聯網所提供的是一種“盡力而為”的服務,在傳輸質量方面并沒有保障機制,特別是網絡帶寬,丟包率,時延等經常變化,很不穩(wěn)定。因此對因特網業(yè)務質量進行監(jiān)測與評估具有重要意義。 本文首先從因特網質量監(jiān)測系統出發(fā),對整個系統的結構與功能進行了介紹,緊接著介紹了因特網業(yè)務質量監(jiān)測相關應用層與傳輸層協議,然后歸納和總結了因特網業(yè)務質量監(jiān)測的相關指標。在論文接下來的部分中主要對因特網業(yè)務質量監(jiān)測與評估的關鍵問題進行了研究。 首先對因特網業(yè)務質量監(jiān)測系統中的視頻業(yè)務質量監(jiān)測模塊進行研究,主要介紹了視頻業(yè)務監(jiān)測模塊已經實現的功能,并且詳細闡述了視頻業(yè)務質量監(jiān)測模塊需要優(yōu)化和改進的功能以及這些功能的具體實現。使得優(yōu)化和改進后的視頻質量監(jiān)測模塊支持對主流視頻網站的主要視頻格式的質量監(jiān)測。 接著對路由出口監(jiān)測業(yè)務進行研究,詳細說明了路由出口監(jiān)測業(yè)務的研究意義以及路由出口監(jiān)測模塊監(jiān)測點以及服務器端的詳細實現。同時對該系統得出的可疑路由結果進行分析,驗證系統的正確性。 本文最后對因特網業(yè)務質量主觀綜合評估進行研究,提出了一個業(yè)務質量主觀綜合評估模型,對因特網業(yè)務質量監(jiān)測系統監(jiān)測到的業(yè)務提取出關鍵指標并進行質量綜合評估,從而來反映用戶體驗。
[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.
