提出了基于Java和简单网络管理协议（SNMP）的动态层次型分布式网管系统模型，解决了中间层管理者动态信息模型问题。利用Java语言的可动态加载特性实现了流动代码机制，利用第3版的SNMP的安全性保证了代码的流动。实现的原型系统的性能包括时间消耗的测量和分析，该模型具有简单、轻便、灵活和实用的特点，更新用例显示了该模型的有效性。
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.
