Design And Implementation Of Network Management System Based On XML

The increasing complexity and heterogeneity of modern networks are making network management technologies and systems more important. It is the key for the network management to find an efficient method to monitor the network and design the effective management function of the network management system.XML-based network management, which applies XML technologies to network management, has been proposed as a new way to existing network management. The use of XML in network management offers a capability to define complex network management information and the XML document can be transferred on network easily.First, this paper introduces the basic concepts of network management and analyzes the existing network management techniques. Then designs and implements a network management system based on XML. It carries out configuration management, performance management and fault management. The configuration management implements the network topology management, device's basic information display and device's MIB view; performance management provide many charts to display different protocols' traffic; and fault management model can report the real-time fault and analyze the possible reason of why the fault occurred.The XML-based network management system adopts hierarchical network management architecture: there are many distributing managers controlled by a super manager called manager of managers (MOM). The MOM communicates with distributing managers in XML. The distributing managers manage network equipments in SNMP. There are two parts of distributing managers: one is XML/SNMP gateway. The XML/SNMP gateway implements interaction translation of XML and SNMP. The other is network management system based on SNMP, which can be used to manage the small Internet. Using this network management architecture, we can manage the large and heterogeneous networks more efficient.
