A Model-Based Object-Oriented Topology Specification for Network Management

Abstract

As the growth of Internet and web applications progresses repaidly, the network management becomes more and more important. Although most network management systems are able to collect network traffic data and alarms, they can not automatically analyze the collected data to find the cause of network faults, if any. As part of an ongoing project to develop an automated network faults diagnosis system, this paper presents a MODEL-based specification that can be integrated with NMS to provide the ability of describing the network topology. With the expanded MODEL class hierarchy, we can also show the OSI layer 2 devices in the topology map. To implement our work in the real world environment, we use the HP Open View to display the processed topology data. Since relational databases are used in Open View, we also derive suitable mapping rules to transform topology description objects to relational tables.
