| With the development of civil aviation by leaps and bounds, all kinds of information network system in airlines, such as civil aviation airport group units obtained the widespread application, IT information has infiltrated into the daily production and business operation and management, the direct relationship between a civil aviation enterprise management strategy implementation, and innovation and development. As the civil aviation airport, in flight operation, passenger services, freight services, logistics, tourism plane, OA office, ticket distribution, such as a variety of business types of decision are achieved in information technology. In order to meet the demand of the rapid development of information of civil aviation, the airport aviation companies have built their own data centers, haihang is first constructed for the entire airport group private cloud in different business sectors, realize the small business operation and management of the plates, enhance the enterprise efficiency and competitiveness. Therefore, IP information network system used to meet the demand of diversified information at the airport has been the trend of The Times.This article adopts the method of engineering case study analysis to airport information content and elaborates the design scheme and design. Planning through the network topology, the actual deployment of IP network, provide users with a variety of airport services business. According to the network standard system structure, determine the network topology, select the most appropriate according to the topology network equipment, topology and combined with the actual site, deployed, IP network connectivity and stability test, finally finishing documents and sum up the experiences of engineering projects.The paper includes five parts. The first part is introduction, put forward the problem background, research purpose, content and significance, and so on. The second part is to the kunming airport information network system planning and demand analysis, and a brief description of the whole. The third part is the actual topology network structure of kunming airport information system and the specific configuration of network equipment selection. The fourth part is the network IP address planning and allocation of VLAN ID, so that the network is simple, flexible and extensible, reasonable control of the broadcast domain, a uniform stability. The fifth part is the conclusion, summing up experience, results and conclusions. |
