With the rapid development of campus networks,operation status of network and service quality of key business must be considered as important factors for management and maintenance of the campus network,evaluating the network performance by analyzing network traffic and performance parameters has become an important means of network reliability research.Studying the reliability of campus network to start,with SNMP traffic monitoring technique,a campus network reliability analysis strategy is proposed based on macro-traffic analysis.A monitoring architecture which is centralized control and distributed measurement is implemented in this system.The whole network is monitored by applying the measure of server logical layering and the technology of regional agency monitoring.The functions of network equipment information display,macro-flow monitoring,abnormal traffic prediction and alarm are achieved.The experimental results show that the proposed system can analyze the reliability of the network more effectively,keep abreast of the network load conditions,rapidly discover the bottleneck of network performance and find out the reasons of the decline of reliability according to the analysis results.
