Intranet Network Management Based On Open Source Project

With the rapid development and widespread use of network technology, computer networks has infiltrated all areas of socio-economic, it plays an increasingly important role in socio-economic development. The scope of the network is increasing, and the network structure is becoming more complex. These factors have greatly increased the difficulties of network security operations and daily managers urgently needed a practical NMS to help them management. Network in the performance of real-time network control, monitoring network failures, network performance analysis to maintain the normal operation of the network.Nowadays because of increasingly complex network structure and multi-vendor network equipment, network management must be made to comply with certain standards of the network to ensure normal work and compatibility between equipments. On this basis, various ISO standards have been promulgated, the more famous standards are OSI standards and SNMP standards. SNMP because of its simple practicality, easy to achieve, in fact it has become a network management standards in the area, and has been widely supported by equipment manufacturers. And the visualize of NMS has become an important trend its development.The introduced network operation monitoring system uses SNMP standards for the management of network equipment, and use real-time image to display network equipment status. Aim at a traditional NMS' s difficult operation, not practical, poor compatibility, the system provides visual, business-oriented, user-friendly, integrated network management platform, achieving interactive networks topology browsing, network operation monitoring and real-time alerting failures, equipment panels real-time observation . In the level of the system, it can be divided into network devices monitoring layer, storage layer and the operational processing layer. It uses the Open Source projects codes, thus shortens the development cycle and enhances system's flexibility, which can be expanded.The main problems I solves in the system are:1. Use program to realize SNMP commands and communicate with actual network equipments;2. Network devices monitoring: This is a basic module in system, it solves how to use described document as the carrier network through SNMP standard agreement to gather and processing network information;3. Interactive network topography generation: how to use outstanding interactive capacity of Visual C to generate interactive network topography which is practical and reflects real physical links;4. Network operations monitoring system warning: how to judge and how to trigger events when the network link is failure. At the same time the four modules: network described module, network devices monitoring module, interactive network topography module and the alarm module will be described in detail in design and implement.
