The Research, Design And Implementation Of SNMP-based Campus Network Management System SVIEW

Today CERNET has already gradually grown up. The development is flourishing in China. The campus networks have occupied more and more important position and effect widely in colleges and universities, where the network administrators pay more attention to make networks working stable and efficient. Because perfect network management software can make network operate better, so it is important to study and develop thepowerful network management software. The paper focuses on the design and development of SVIEW network management system based on SNMP protocol through the study on the campus network of Shi He Zi University. It has mainly accomplished the following jobs:Explore and implement the topology automatic discovery system mainly based on L3 switches in backbone network. It puts forward a new algorithm that has realized the topology automatic discovery of link layer. It can also discovery the dumb equipments. Explore and implement the network topology map generation and layout with well-designed algorithms and programming that make topology map more clearly. Explore and implement the automatic alarming module that realizes SMS alarm, the Net-Send alarm and messagebox alarm.Explore the data acquiring methods of network traffic and explore the formation of traffic,and implement the monitoring to the network traffic flow.Research and implement the host-locating module that provides a good way to determine the equipment port rapidly the user host connects to.After the system development completion, it has been running in Shi He Zi University campus network. Now the system runs smooth, stabile and reliable, and it has reached the original developing target and has good effects.
