Abstract


With the popularity and the rapid development of network technology, computernetwork has penetrated into all fields of work and life. Scale expansion of the computernetwork, the sharp increase in the complexity, increasingly complex heterogeneousnetwork monitoring and management plays an increasingly important role in the currentnetwork environment. Network monitoring and management system is the first underthe premise of ensuring high security and good performance, the need to quickly andeffectively grasp the entire network topology, thus real-time network equipmenthardware configuration, performance monitoring, fault diagnosis.As we all know, cloud computing is now regarded as new technology sector of therevolution, it brought a fundamental change to the way we work and business models.Combination of virtualization technology, parallel advanced technology, distributedtechnologies and network computing technology, physical concentration of theenterprise distributed hardware resources, data resources and IT network resources, theformation of large-scale data center infrastructure and cloud computing throughvirtualization IT resources to shield the heterogeneity of the different physical devices,virtual into the physical resources based on standardized interface logic is completelystandardized and consistent logical computing resources (virtual machine) and logicalstorage space, scalable, on-demand configuration provides IT services. Which makeshighly centralized management of resources, disaster tolerance significantly improve,improve resource utilization, and significantly reduce running costs; various corporatedepartments competing to introduce popular cloud computing technology. However,cloud computing network architecture flexible, heterogeneous and complex newchallenges to the traditional LAN monitoring and management. Most of the monitoringsoftware is a single network or cloud computing platform; and respective standards andfocus; urgent need to develop to be able to demand configuration, while monitoring thesafe and effective local and cloud platform network monitoring software. Newmonitoring software first LAN achieve parallel cloud platform network monitoring;followed by monitoring performance and standardized implementation, and finally is a real-time visual display of monitoring information.Thesis is background of campus teaching and research specific private cloud LANmonitoring the, focus on monitoring the security of Trusted Strategies, to build a newsecurity a trusted LAN monitoring system based on the SNMP protocol, to protect thesecurity and stability and real-time monitoring capabilities LAN, finally in order todeploy, install, control, manage, monitor cloud systems with Friendly interface andconvenient operation. System innovation network proxy SNMP monitoring model,combined trap to guide the the polling mechanism real-time acquisition equipment data;encryption for data acquisition and delivery process measures to guarantee the securityof data and transmission; monitoring device node binding its corresponding the IPinformation through the authorization to ensure the operation of nodes in the case oflegitimate security to pass; the final traffic data collection network device interface,dynamic online measurement, real-time monitoring, network anomaly alarm function;collected data analysis of network topology discovery, network fault location, and thusprovide the basis for reliable operation and performance optimization for the stability ofthe network.
