Abstract: To overcome the shortcomings of traditionally initial SNMP network management, the network performance management model through mobile agent was presented. The model paid attention to the popularity of SNMP and integrated the technology of mobile agent into one so as to resolve the problems of network resource occupation and poor dynamic extensibility, thus improving the efficiency of network management. Its construction and work procedure were illustrated and compared with those of the traditionally initial SNMP. A conclusion was drawn that this model has such advantages as shorter response time, less bandwidth consumption, better adaptability and more intelligent than the initial one, as proved via simulation and comparative analysis.
