Abstract：A new dynamic hierarchical network management system model based on Java and Simple Network Management Protocol (SNMP) is proposed. The model supports dynamic information model upgrades of mid-level manager. The mobile code mechanism is implemented using java dynamic class loader and reflection. The security is guaranteed by using security mechanism of SNMP v3. A prototype is implemented and some upgrade use cases is described to show the availability of the model. The performance including time consume is measured and analyzed. The experimental results show that systems based on this model are simple, elegant, flexible and practical.
