The Research And Realization Of Traffic Monitoring And Treatment Of Anomaly Traffic In Campus Network

Along with the University of digital campus applicationinformatization degree rise ceaselessly, a variety of network applicationsbecome more and more abundant, led to increasing the difficulty of networkmanagement. The campus network widespread cyber source abuse problem,therefore, how to guarantee the network availability and key business smoothrunning of university digital campus network, the development will play avital role in. Campus network administrators need to have correspondingtechnical means, clear understanding of network bandwidth usage in a varietyof applications, user behavior analysis of flow, so that a rational planningand allocation of network bandwidth, effectively guarantee the normaloperation of business critical applications.Establishment of traffic data collection, analysis, monitoring andearly warning system, all network nodes deployment flow monitoring systemfor network traffic collection and statistical analysis, when it isdiscovered that the network traffic anomaly can immediately alarm based onflow analysis results corresponding flow control means, It is important tothe campus network safe and stable operation. This allows for real-timemonitoring of network security situation, once found anomalies can quicklylocate the source of the attack and through traffic monitoring system onthe attack source isolation, prevent network attack behavior of diffusion.In this paper, the current campus network traffic anomaly analysis techniqueare studied in detail, the design and implementation of campus networktraffic anomaly analysis system, used to solve the problem.Net flow acquisition technology are analyzed, and then focus on thecurrent campus network exists in the main anomaly traffic sources includeworms, ARP virus, denial of service attacks as well as the P2P networkbehavior were analyzed in detail, put forward to these abnormal flowanalysis and detection method.This paper describes the design and implementation of campus networkbased on NetFlow abnormal traffic analysis system, the campus networktraffic management control. This system to the campus network traffic datacollection, analysis and display, realize the network anomaly trafficmonitoring, traffic statistics and comprehensive analysis of flow, and cantimely discover network attack.
