Market competition has become the trend of globalization. For large enterprises, in adjusting the development strategy, must take into account the markets global competitiveness strategy, and all this information platform will also be based on the principle of the use of computer networks and network planning technology to the network in order to ensure patency. Intranet is an international Internet technology in the enterprise or within a closed user group applications. Intranet is the use of Internet technologies, especially TCP / IP protocol and the completion of the enterprise internal network. This technology allows interoperability of different computer platforms, and do not have to consider its position. That is what the user can visit any or from any computer access. From the start the whole enterprise class network needs analysis, based on the mainstream stage cisco network equipment company selection, with the goal to build the most suitable network topology, designed with network technology. As part of this implementation to build the simulator GNS3 network topology, the use of cisco device operating systems unzip-c2691-advsecurityk9-mz.124-11.T2 for all equipment within the core topology IOS, routers and switches using SecureCRT for the configuration, and view the experimental results to verify that the network meets business needs.
