In order to improve the stability, validity and reliability of network management, the management architecture of multi-agent network is analyzed, and the communication and language between the multi-agent are introduced. Finally, a Distributed Network Management Framework based on multi-agent is presented. The functions of each module and mutual cooperation process in the framework are outlined. The performance of the framework is analyzed. Agent technology is combined in the management mode which adopts multi-agent cooperation model based on wizard-style. The multi-agent technology is fully applied in network management model. So, the network management efficiency is improved effectively.
