Abstract: A mobile-agent-based hierarchical network management model is presented to get rid of the shortcomings of conventional SNMP centralized network management. Integrating the technology of mobile agent into the model, a concept of intermediate mobile manager is proposed to solve the problems of over-occupied network resource and poor dynamic extensibility, thus improving the efficiency of network management. Its construction and work procedure are illustrated and compared with those of the conventional SNMP. A conclusion is drawn that this model has such advantages as less bandwidth occupied and higher flexibility than the conventional one, as proved via simulation and comparative analysis.
