Based on the latest researches on physical topology

a distributed network management system named D-CBNMS with load balancing was proposed.Firstly

the system had very good scalability to extend the management scale by dynamically increase manage nodes.Secondly

it had the ability of fine-granularity load-balancing to adjust the load of management nodes.Thirdly

it had topology-awareness ability that allocates management tasks to the nearest management node

utilizing the detailed physical topology.D-CBNMS had been applied to the management of CBISNS（community broad-band integrated services network system）

which was a total solution for CPN（customer premises network）.Experiments show that D-CBNMS can reduce effectively the bandwidth occupied by management data.
