Abstract


With the development of network technology, network application has penetrated into all aspects of social life. Network video has been familiar at the same time, this new type of network interactive TV to watch TV the way is full access to people's daily lives. While watching TV to see a smooth, clear picture, which is palatable. For interactive television, high-quality picture quality is not only to establish effective video codec, but also requires a high-speed and stable network system as a basis, the two complement each other, in order to give the audience a perfect visual enjoyment. Therefore, in order to fully assess the quality of the network to carry video streaming services, it needs to make a comprehensive and accurate monitoring. The network quality monitoring system is a real-time monitoring of network quality of the run 3TNet video streaming services such as IPTV. This paper analyzes the monitoring system involves the Linux system data capture process, parsing, filtering and interaction technology. Subsequently, by analyzing and comparing the existing mainstream Linux interface technology to determine the selection of a suitable system Qt graphical user interface application framework to design and implement the system interface requirements of sustainable development. Then, based on an analysis of the existing mainstream data capture and retrieval filtering technology and to combine 3TNet video streaming features, improved the efficiency of the system retrieves a high reliability, stability, network monitoring system for the the 3TNet video streaming business. The system can be divided into two parts of the user layer and the core layer. The system kernel layer of the video stream through the high-speed capture, analysis and retrieval, a few channels of the desired monitoring the quality of real-time network statistics of the video stream obtained from the video stream 3TNet business. These statistics in the system passed through interactive technology to user-level interface. The video stream business network monitoring system has the following features: 1, high stability, and support for multiple network protocols and the corresponding exception handling, and does not cause a system crash due to abnormal data. 2, high efficiency, high-speed video streaming services the 3TNet on the network for high-speed data capture and analysis results to improve the filter retrieval function implementations to speed up the system retrieves filtration rate, improve the efficiency of the system according to the 3TNet Internet video streaming features, The system can reflect real-time to the technician monitoring the video stream quality level of the pros and cons. 3, friendly man-machine interface, supports a variety of system configurations, provide the technician with a beautiful and convenient operating environment.
