Analysis And Design Of A Tobacco Company Network Reconstruction Plan

With the continuous development of Enterprises Informationization construction, in order to support a variety of application needs, Infrastructure Network Architecture also need to be adjusted and evolved accordingly. The thesis is a part of the project of Network reconstruction based on the tobacco company in one city. According to the Bureau of the network construction technology and management requirements, combined with the specific circumstance of the existing network structure and network security, establish a safe,reliable,stable integration platform system.Firstly, the thesis briefly introduces the background; the design basis, the transformation range of project construction and has a brief Description for the overall design of the reconstruction project. Analyze existing and potential security risk in the current network and propose a scheme partitions the domain in network reconstruction. Work out an optimal design solution for network reconstruction match the company in the incoming5years by analysis network architecture, security construction, basic operation environment and other aspects.Secondly, through on-the-spot investigation in brothers units, summarizes the advanced experience, get the technical document support from system integrators and network equipment manufacturers, analysis and study the existing network architectures,"Core-convergence-access" three layer network architectures is generated. At the same time, expound the optimization retrofit scheme by combining with the basic equipment operating environment (such as:room construction, mechanical and electrical engineering, access control security, fire extinguisher system) and other nonfunctional requirement ensuring basic operating condition for the whole network operation.Finally, according to the guiding ideology of the level of protection, this article focuses on the network construction and network security construction of two aspects. Design the method of modular architecture partition domain using on the basis of existing networks, clearly define and distinguish between different security level functional areas, to realize the network security policy and security rules in different regions. Using the network architecture is scalable, flexible, high availability and security...
