[Abstract]:Since 1969, the Internet has developed into the most popular mass media, and infiltrated into various fields of modern society. As an indispensable organic component of human society, the Internet is carrying high-definition picture text and other data and information media technology with rapid development through the network transmission medium and the agreed communication protocol. At the same time, with the extensive growth of the network scale, various heterogeneous networks melt into the Internet, and the number of network users expands rapidly. The phenomenon that the traditional network structure can not adapt to the rapid change, so the network supervision department urgently needs to detect its flow information, to achieve the role of effective network control. This paper focuses on the core technology of network traffic detection, analyzes the advantages and disadvantages of various network detection technologies, and designs a set of traffic detection scheme based on this. Experimental results show that this scheme can efficiently and accurately detect all kinds of traffic, can effectively manage the network and provide different services. The research contents of this paper are as follows:. 1) deeply analyze the current network detection technology, compare the advantages and disadvantages of each technology, utilize the advantages and disadvantages of various detection technologies, and put forward a set of network traffic detection scheme innovatively. 2) through careful study of various detection techniques, the parameters of network detection are summarized to form a new feature database, which has a rigorous format and can be quickly analyzed and loaded quickly. By studying the communication process of OSI seven-layer network protocol model and combining the input information needed for detection, the processing mechanism of auxiliary detection is put forward, and the detection speed is improved. Reduced system power consumption. First of all, the Google talk communication software is used as an example to grab data samples, analyze, write into the feature database, and analyze the test results. The test results show that the testing system has the advantages of wide detection range, high detection precision and strong feasibility.
