摘　　要：基于物理拓扑发现的最新进展,提出了一个负载均衡的分布式网络管理系统D-CBNMS。该系统具有良好的伸缩性,允许动态增加管理节点以扩大网络管理范围;具备精细的负载均衡能力,可以动态调整管理节点的负荷;具备拓扑感知能力,可以利用详细的物理拓扑信息,把管理任务分配给距离最近的管理节点。D-CBNMS系统目前已应用在用户驻地网解决方案——社区宽带综合业务网络系统中。实验表明,D-CBNMS可以有效降低网管数据占有的网络带宽。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.
