The Design And Implementation Of Deep Packet Inspection System Configuration Management Module

With the rapid development of the network, the use of computer networks becomes more and more common. It brings convenience to people’s daily lives, but at the same time, it also brings some problems, such as network information may contains violence, reactionary, or certain bandwidth is occupied, and so on. This makes telecom operators, enterprises and institutions a greater or lesser bad influence. So DPI technology becomes important in network transmission and development process. On the basis of the content detection system realized, this paper designs and implements the configuration management module, it uses the browser to configure and manage the system by using the browser, which takes convenience for staff.Firstly, to solve this problem, this paper does the research for domestic and international status, and describes the DPI technology applications on the scene and industry trends described. At the same time, the paper introducts the related technology used detailly, including the principle, features,functions of DPI technology, as well as a Web development platform built on the Linux environment, using the ExtJS framework and MVC pattern.Nextly, the paper describes the working principle of the whole system, and divides and describes the various functional modules based on this process. Subsequently, a detailed description of detailed design and implementation process for the configuration management module, the data packet information list display, sensitive information configuration, user management, network service identification, as well as packet capture and parsing.Finally, to the implemented configuration management module and the packet capture, this paper establishes the testing environment, and then analyses the results, which completes the functional requirements of the system.
