Because traditional network management have been unable to meet the requirements of network development and the passive management status, the operation and maintenance of the network information systems should be managed uniformly. The status of Kailuan Group network management platform technology, integrated network management platform system architecture design, and network infrastructure of functional design were introduced. It was pointed out that through an evolutionary approach for design of the integrated network management system, and management of the network infrastructure platform, the networks and application systems could operate efficiently and stably, and warning and alarm could be realized before a failure, thereby achieving a more timely, comprehensive and transparent network monitoring.
