Simulated Network Topology Configuration Generation And Fault Alarm Simulation

The main content of network management is to manage network resources and network activities,whose purpose is to ensure the normal operation of the network as long as possible,and to find and fix problems as soon as possible when there is a problem.With the rapid development of the Internet,and the emergence of new technologies,network management is facing new challenges.Especially the rapid development of Internet technology makes modern network size continue to expand,and the network nodes alter more frequently,so that the management of computer networks becomes more difficult.It is important means to reflect the network layout conditions to obtain configuration information.But it is very difficult to get details of the virtual network because the large-scale network's topology changes frequently.It is hard to manage the network effectively.In order to solve the problem,a method to generate network topology configuration resource data is designed in this paper.According to the configuration information generated by this method,the topology of the network can be simulated,and facilitate the NMS to manage the network.Generally,an XML file is used to save configuration information instances in network management.So the problem is generating XML file which holds topology configuration instance information in terms of the information model of network topology and simple topology information.Although there have been some software,such as XMLSpy,which can generate XML instance document based on the information model.The generated XML instances don't have semantic features,which can not reflect the connection between topology nodes.The configuration resource data generation method designed in this paper is driven by network information model.According to the results of Topology Builder the method allocate values for an instance so that the generated instances support topological semantics.According to the results of this method the network topology can be generated.Besides,the method is flexible and universal because of Reflection.This design of this resource allocation data generation method,network information model driven configuration property values for an instance is generated according to the results of allocation Topology Builder to ensure configuration examples it generates topology support semantic instance final output profiles meet Topology logic,can emulate the success of the network topology;and because the method is introduced reflection and have great flexibility and versatility.On the basis of the network topology configuration file,according to the semantic information contained in the instances,the propagation between network faults and alarms is simulated in this paper.It is meaningful to research the network fault management and alarm correlation analysis.
