Research And Realization On The Analysis, Monitoring And Alarming Of Network Performance System

Along with the rapidly development of internet, the scale and structure arebecoming more and more complex. The network performance monitoring and analysishas become the main task of network management system. It has great significance toimprove network service quality, and overcome the network bottlenecks. In this paper,the system of network performance analysis and alarm is designed and implementedbased on SNMP network management model, after depth-study in performance datacollect, data analysis, exception alarm, and performance evaluation.This paper firstly discusses the SNMP network management system and relatedtheory, advantages and disadvantages of traditional network performance models arealso analyzed. On this basis, designs the overall structure and hierarchical model,real-time monitoring of the host communication model, and link flow calculation modelof this system. In order to improve the accuracy of alarm, this paper design andimplements kinds of alarm mechanism. Queuing theory model is used in this paper toanalysis the entire network congestion rate and utilization rate, and then, evaluate thenetwork performance by the fuzzy inference model. Though the test and analysis, thesystem which is designed and implemented in this paper has certain advantages inefficiency and accuracy compared with the traditional system.
