Outgrowth of the development of distributed computer environment has caused local resources to be connected and shared by means of networks. A user can utilize far much efficiently way through the ...networks. Without effective network management, a user can not user them efficiently. It will lead to inefficient computing work. Currently, SNMP (Simple Network Management Protocol) and CMIP (Common Management Information Protocol) are defined as management protocols. Both of them employ Manager-Agent model. The paper suggests a reliable distributed network management platform which can manage TCP/IP network with SNMP and OSI network with CMIP in an integrated manner. Based on the new platform, it designs and implements configuration management, performance management, and fault management. The new platform aims to reduce network traffic and system workload which have been concentrically loaded on a manager in the traditional Manager-Agent model. Also, the new platform improved fault tolerance capability. The platform, using management distributor, provides network administrator with independence of low-level management protocol.
