【正文】 acket Tracer 軟件進(jìn)行網(wǎng)絡(luò)仿真配置和安全設(shè)計，給出了網(wǎng)絡(luò)規(guī)劃設(shè)計解決方案。s largest information center for the world, more and more people use the Inter to the liberation of their lives, and they use the Inter to plete almost all of the things in real life. This design is base on the actual demand of a smallmiddle enterprise, through the design of the work infrastructure, the design of securitybased work configuration solution, the design of the infrastructure of sever farm, the design of advance services, to deeply investigate into the problem we met, and the service related to the work design. This design is mainly focus on the requirement analysis, topology excogitation, IP address design, server farm and work security design. This article is focus on the analysis of work topology design and use the Cisco Packet tracer to build a simulated infrastructure to illustrate what I have done.
