Analysis And Design Of The Flow Analysis System

With the rapid development of the Internet, the emergency of varieties of network applications are greatly enriching people’s livings, while bringing challenges such as continuous network bandwidth consumption, difficulty of communication content monitoring and high frequency of network security issues. Effectively monitoring is the priority of network operators to ensure smooth running of the network while providing differentiated services to customers.To start, the paper introduces the significance, research background, and status quo of the traffic analysis system, describes the goal of the upcoming design, and elaborates developmental approach and related technology. Then in requirement analysis, all the professional, functional, data and systematic environmental requirements are analyzed, with process charts and use case diagrams drawn, and use cases described. Following is the design of the overall architecture and all function modules, including modules of network traffic data collection, analysis and P2P monitor. The design is detailed with the help of package diagrams and class diagrams and sequence diagrams and activity diagrams, while the database is designed on concept and logic basis, followed by E-R diagram and table structure. To actualize the system, deployment diagrams and component diagrams are specified, as well as partial procedure, core code and function interface. In the final part, the paper gives a summary and outlook of the traffic analysis system studies.
