Design And Implementation Of IPv6 Network Traffic Measurement Based On Linux

With the rapid development of Internet, new type network applications are emerging continually and the demand of network bandwidth is increasing. A variety of applications based on Peer-to-Peer technology use up a lot of network bandwidth. So, network overcrowded and users hope to understand the component of the traffic and identify all kinds of network traffic. Currently, many applications and protocols use unpredictable ports, non-standard ports or ports shared other protocols. It is impossible to identify network traffic by simply detecting the number of ports. IPv6 network are widely deployed and bring some new problems. For the above reasons, we need to study the traffic measurement based on IPv6 network environment.This paper provides a solution to measure IPv6 network traffic. The three preceding chapters introduce the basic concepts, classification and significance of the network measurement and the framework of the traffic measurement based on IPv6 network environment. The fourth chapter discusses the data collection module, which involved with the general approach of data collection, data capture in IPv6 network environment and data storage. Next, the fifth chapter focuses on the design of data analysis module. The ideas of the analysis from the network layer and the application layer are discussed in detail. Foremost, we explain L7-filter and pattern definition file. The sixth chapter introduces the data display module, which use the command line mode and the web mode. The seventh chapter focuses on the setting-up of the testing environment and the results and analysis of testing. Finally, the eighth chapter sums up the technical characteristics of the network traffic measurement and gives some considerations for further study.
