Owing to the increasing great complexity, computer network systems require more sophisticated management strategies to be adopted so as to guarantee adequate levels of performance. The classic centralized paradigm, adopted by SNMP, which was once appropriate in the prevenient phrase, has posed problems with the explosive expansion of networks, as well as other centralized models. Mobile Agent (MA), owing to its capability of implementing a distributed system, represents a challenging approach to provide network management with high performance. In this paper we analyze the network management structure model based on MA at first, and then we put forward a reference scenario based on MA and compare it with the traditional model. We also describe a prototype implementation based on our mobile agent system named MAS. Finally, we do some experiments to verify the performance of our framework prototype.
