Design And Realization Of Ship Designing Company Network System

With developing of the shipbuilding and updating of the basic network equipments and correlated techniques, the demand of internet's business and its security is increasing rapidly in some National Ship Design & Research Company. The research on the network plat of the ship designing is due to the ship design's practical requirement, and can make the large-area project of networks normative, standard, modern, and efficient. Through the research above on, the competition of National Ship Industry in the international market will be enhanced, the work is to be extended, which can also make more opportunities of occupation.Based on engineering background, this thesis designs and realizes a fast, advanced and reliable network system for ship designing in order to achieve the function of ship designing and OA (Office Automation). The system achieves the information exchange with high speed and security based on OA and demand for ship design. The work mainly consists of:The First part is the analysis and design of the ship designing company network system. Based on the related theory, the author divides it into several subsystems combining with the reality condition. And so on, the essay expatiates analysis on demand and network flux, network topology, equipment selecting, design on IP address and Router protocol, network security etc. to each subsystem.The realization of the ship designing company network system is another important part of the thesis. Based on the configuration of network and the project to carry out which are achieved by the analysis and design on the network system, the author builds up virtual network, installs hundreds of network equipments and also debugs them. After all, the connectivity and reliability should be checked to make feasible and controllable system of network management. The network system designed operates in a steady and natural state up to now, which also receives approbation of the colleagues and leaders.At last of this essay, the advantage and disadvantage of this system designed in this paper, and some aspects improved in the future also involved.
