The Research Of Text Content Network Behavior Analysis System

With the rapid development of network technology, the Internet has become an indispensable part of our learning, working and living. In daily lives, people using the Internet more than ever before. But now there is bad information on the Internet. Various departments of the major issues facing is how the content of online information on the regulation and control. This problem was particularly prominent colleges and universities. How to effectively prevent the adverse information on the environmental pollution caused by college network is receiving increasing attention colleges and departments, how to achieve an effective analysis of network behavior analysis system to accurately conduct the user's network to ensure that colleges and universities in the healthy development of the network environment has become an important research topic.In this paper, our in-depth study of the text-based Network Behavior Analysis System. The main work started from the following aspects:(1) This paper discusses the relevance of network behavior analysis theory; this paper introduces the packet capture technology, and discussed in detail the TCP/IP protocol model and its working principle; a brief introduction of the Ethernet data package and sub-frame, and focus on the IP and TCP stream segmentation data of recombinant technology, the last of the Hypertext Transfer Protocol was discussed;(2)Focused on text-based Network Behavior Analysis System Design and Implementation; the operation of the system environment and development environment is introduced and given the physical and logical system architecture; Discussed the analysis of network behavior to deal with processes, introduced and implemented packet capture and protocol analysis, and ultimately restore the user's network behavior;(3)Studied the text of the analysis algorithms, focusing on the latent semantic analysis algorithms, and application of latent semantic analysis algorithm to the network behavior analysis system, and ultimately to achieve effective network behavior analysis.Text-based network behavior analysis system deployed in the switched Ethernet environment, through the bypass means to monitor the user's network behavior analysis and to determine the legality of the act, in order to control network behavior has laid a solid foundation.
