Enterprise work construction is a large and plex project, which not only provides businesses with modern office and information resources sharing platform, and can also provide a wide variety of application services. In the enterprise work construction, it is necessary to take into account the actual needs of the current business, but also taking into account the corporate work scalability and backward patibility to facilitate business in the future to upgrade the work. Throughout the work design process include: the enterprise needs analysis, design the work topology, select the work technology, work equipment selection, server configuration, cabling design and implementation, and work security design. The project is based on a mediumsize enterprises of various work needs while planning to get a work system design, the first enterprise to conduct a detailed needs analysis, including application service requirements, security requirements, and scalability requirements, determine the work services to be provided and the use of equipment and wiring and work topology options. Thesis focuses on the design and analysis of enterprise work using Packet Tracer simulation software for work configuration and test the relevant results, which gives work planning and design solutions. Key words: Enterprise work, equipment selection, work technology, work topology, enterprise security 目錄 III 目 錄 摘要 ................................................................................................................................I ABSTRACT .................................................................................................................
