Abstract


With the rapid growth of the Internet network traffic , and how effective management of the Internet has become an important issue . Network traffic statistics provide important information for the management and maintenance of the network , these data are very important for the planning of the network architecture of the network , improve network performance , and network security protection . Therefore , the monitoring and analysis of traffic on the Internet has become a prerequisite and condition for the effective management of the Internet . The subject comes from playback and annotation data set based on the data stream to generate technology research projects , and discusses scalable flow generation system based on the IPFIX protocol . Solve the serious flow-based network traffic monitoring packet loss , high-speed real-time online network flow clustering , a single stream output format , and a smaller amount of information contains some of the problems . The paper first describes the network flow , scalable the the stream output Agreement IPFix, high-speed network to capture the basic concepts of the technical PF_ring and clustering technology . And then describes the system architecture scalable flow generation system , network packet capture module , several modules of the network packet shunt module, clustering module of the network flow , network flow export module and network flow collection module provides a brief introduction . Followed by a detailed description of the clustering module introduces the basic concepts involved algorithm , described algorithm framework , and , respectively, the specific features of the sub- function function , meaning , the concrete realization of the narrative . The article also described the case of the system-related test , test results show that the system can achieve the object of the intended design . Finally , the article summarizes the research work and the prospect for future work .
