Campus Network Management Flow Analysis Technology Research And Implementation

With the continuous expansion of network scale, heterogeneous network has continuously deepened, computer networks have become increasingly complex, college access bandwidth of a few hundred Kbps from the original is very quick and sharp rise to hundreds of Mbps or even Gbps, but everybody because it gives me the network of export is becoming increasingly crowded, the additional bandwidth being consumed rapidly, and now the network only knows the total number of users and the total bandwidth consumed can not control what users are using the application, the bandwidth used by how much. Therefore, we must use the relevant technology to analyze network traffic, and some users conduct effective control,Protection of critical applications, it is important the user's normal use. Therefore, the urgent need for the campus network management of network traffic in real time, on-line monitoring and management.Network traffic monitor network traffic to understand the characteristics of one of the important means. Through the network traffic monitoring network to detect anomalies can be detected congestion link, warning denial of service attacks, and the basis of detailed flow information to achieve fault location and recovery; be kept informed of the size of the network carrying the business to understand the user application intensity, frequency, load and other behavioral models and found that the network trend of development of new applications, communication protocols to guide research, development, and network equipment network upgrade plan.This paper studies in detail the network traffic monitoring technology related research, based on the analysis of network traffic monitoring and analysis of related issues that exist to study the flow of data collection, traffic data analysis methods and the deployment of measurement systems, analysis of the current campus network for P2P traffic control of the business identification technology, through the deployment test, put forward a set of campus network flow solution. In this paper are as follows:1) In the definition of the network traffic measurement, purpose and basic theory started research, analyze and compare the Net The basic method of traffic monitoring network, summed up the current flow characteristics of commonly used analytical methods.2) It is designed and implemented for the campus network traffic monitoring and analysis program. Including the research of Shandong Vocational College of Science and Technology campus network traffic monitoring and analysis needs, analysis of Shandong Vocational College of Science and Technology campus network architecture, on this basis, the design for the campus network traffic characteristics of the analysis of test programs.3) In this basis, Shandong Vocational College of Science and Technology campus network traffic monitoring carried out by the export links, the use of monitoring systems to network equipment for data collection, monitoring and analysis of Shandong Vocational College of Science and Technology of export flows outside the grasp of the business flow characteristics of the campus network.
