Application And Research Of Network Analysis In Power Industry

Along with the enterprise information construction becoming more and more deeply, the structure of business application system also become complicated, application server, middleware, database, network infrastructure, application delivery infrastructure components together provide services for user. In this situation, the more involved in the link, a problem occurs more difficult position. The development of information makes many enterprise organization in the security has more risk.In this case, the network operation and maintenance personnel must flow on the network, distribution, application of occupancy communication connection, data packet original content all network behavior and the operation of the whole network to fully understand and grasp, in network performance and security issues, can be fast and accurate analysis of the cause of the problem, locating fault point and the point of attack and its elimination, so as to realize the maximization of the value of the network.The network analysis of network analysis system can deep into the OSI seven layers to analysis and can help to test the whole network. To help the user to monitor the whole network communication, quickly find out the cause abnormal network and security problems, and through the captured data packets, decoding, comprehensive system analysis, diagnosis, and the results reflected in the visual, easy to understand interface or statements, so that managers can quickly understand the network status. Usually, network analysis can provide the managers the dates of fault, security, performance, upgrade planning, network monitoring, network baseline, etc. These data can obtain network panorama information, establish active defense mechanism, so that enterprises can clearly understand the status of enterprise network, to ensure reliable operation of the continuous network provided solid data base.This work focuses on the network through packet capture, then analysis and decoding, comprehensive analysis the diagnosis of the existing network fault, security and the performance and so on various aspects of the application. Network analysis system integration of the industry’s leading network analysis technology, the complex network provide accurate analysis and fast positioning. From the origin of network analysis, the concept of working principle, significance and value and use the basic knowledge of the network management as the foundation, including layered, packaging, port, ARP protocol, IP protocol, ICMP protocol and TCP and UDP protocol, etc.; Then based on the application of electric power industry and the actual demand, through the principle of combining case way the network analysis in the electric power industry, the application of the theory and the practical application, and to solve the practical application. Content including point failure analysis, safety analysis, performance analysis and application flow evaluation.
