Topology Discovery Base On Enterprise Network And Its Application

With the rapid development of the computer network, the network's structure is more complex, the more increasing application of the network, more and more difficult and pressure on the network management. Network management system is based on the network topology information and its importance is obvious. It is a focus for those network institutions to research and discovery with accuracy and efficiency which can automatically discover and collect the information of network topology.Firstly, the paper provides the architecture and the development of the network management system, including the concept, the elements and the functions of the network management system. The paper describes the principle and development of the simple network management protocol in detail.Secondly, based upon the research on network topology technology of enterprise-based network, we mainly adopt the topological technology which grounds on SNMP to the use of finding device message in LAN automatically. This method can achieve the aim that finding the web site in an optimized path way during the whole topological finding process.Thirdly, on this basis, the application of network flow monitoring to enterprise-based network in order to conveniently found the flow control model. This paper gives a typical analysis of TCP flow firstly and acquires the monitoring model of network flow, and it has been used in enterprise network management and achieved a very good effect.Finally, made a deep study of the new technology of the network management, for which the development of the enterprise. One this base, the paper builds a kind of distributed, intelligent, integrated network management framework.
