Planning and design of Enterprise
Abstract: Times continue to wax and wane, science and technology advances. Network is making more and more effect on people life. When you are still in school may only surfing the Internet, you may find that you have after ten years use the Internet to work, which is a network of great power. People’s life and production ways are affecting by the network. The topic is the planning and design for today's small and medium enterprise social networks, the main contents include the following: the purpose and significance of the course, needs analysis, the network system design configuration. The design is based on Cisco equipment, based on the core - convergence - access layer structure to build the network topology, automatically received a useful address via DHCP, by piding the VLAN to control the data traffic on the data link layer, from the three on OSPF protocol relying on DHCP to dynamically assign addresses internal use, and after NAT translation to the outside network.
