Network Performance Detection Based On SNMP

A perfect administrate system of networks is the insurance for computer network to run credibly and steadily, of which networks detection is the foundation. By networks detecting, capability parameters of network equipments can be collected, saved and analyzed; network administrators can get warning massages simultaneously, solve problems promptly, make a reasonable forecast of future network utilization, and thus modify the configuration parameter so that the network can run in an optimum state.At present, most administrate systems of networks are run under UNIX platform which is operated by management orders. The UI of UNIX is not friendly, the management and maintenance of system must be done by professional network managers which requires professional users and better hardwares. In addition, administrate systems of networks and workstations depend on each other, which makes distributing management more difficult. And more, system's expansibility is limited by the API that platform provides, which makes exploitation more complex.According to these problems, the paper brings forward B/S three ties frame of management design scheme to detect network performance, which solves exceeded loads running with low efficiency; releases managers from workplace limitation, and do not need last long time observing network running status; and expansion of network management is improve.The paper has five chapters: the first two chapters describe the relative theories of basic models of network management and network management protocols, and describe the network management based on SNMP and its importance in the network developing. The third chapter discusses the theory and the way of real time detection of network performance, designs the modules of data collection, data analysis, system alarm and the display of Web. The forth chapter actualizes the functions of gathering and processing the performance data regularly from the network equipment, sending warning messages. The fifth chapter tests each module, and the results show that the system achieves the expect aim and the system can detect network performance.
