Design And Implementation Of High-speed Mobile Internet User Behavior Monitoring System

With the high-speed development of mobile Internet, kinds of mobile platforms such as IOS, Android system also update quickly, and a variety of applications are supplied to us. As the result, network communication and network security has become especially important. Protocol analysis technology is needed in the network security of every field, and is applied to various applications and tools. With the aid of the technology, people can quickly understand the interaction process of data transmission and network communication, understand the communication of each terminal and server to send and receive data type, flow rate and content, and then take corresponding measures to achieve the network security monitoring and protection.Protocol analysis technology is restructuring and restoring the packets which are captured under network communication.On the basis of the network protocol analysis and reduction technology, and the traditional TCP/IP protocol reduction, this thesis presents an efficient high-speed mobile network user behavior under the monitoring and control system, and implements it on Linux Redhat AS5. In this thesis, the work of its innovative results mainly reflected in the flowing three aspects:1. For the traditional Internet communication content monitoring system is lack of effectively mobile network monitoring method, this thesis presents a research methods to LTE/4G network and WLAN network monitoring in order to achieve effective management of the mobile internet.2. Research on the technical standards of the LTE/4G and WLAN network, and analysis the feasibility of network monitoring under the mobile network. And put forward the feasibility in the mobile network to monitor the network. On the basis of the traditional protocol reduction platform, thesis proposed a user behavior monitoring system model under high-speed mobile network. The system was designed from capture data to protocol reassembling according to the LTE and WLAN network features.3. Implementing modular the network behavior monitoring system for the convenience of the system in the late development of scalability. The main modules are: The data of EPC in LTE/4G network parsing algorithm implementation, user network behavior data of IP, TCP and HTTP protocol parsing. Finally has carried on the function and performance test of the whole system. The test results show that the system realizes the function of user behavior monitoring in high-speed mobile networks, at the same time, through the performance test to verify the system has superiority and reliability.
