Load balancing is an important factor, which influences the performance of DNMS (distributed network management system). In this paper, a two-layer load balancing scheme is proposed for DNMS based on the latest research works on physical topology. In the scheme, the management tasks are distributed to a number of stations for reducing the burden of center management station, the processing time of every station is balanced to almost equal for fairness and the management tasks are allocated to nearest station for saving bandwidth. Experiments show, compared with the centralized methods and general distributed method, it works stably and save over 26 percent of bandwidth occupied by management data in the testing network. This scheme has been used in an actual application.
