The campus is the portion of the computing infrastructure that provides access to network communication services and resources to end users and devices spread over a single geographic location. The data center is a facility used to house computing systems and associated components. The branch/WAN portion of the enterprise network contains the routers, switches, and so on to interconnect a main office to branch offices or other main offices Internet Edge is the portion of the enterprise network that encompasses the routers, switches, firewalls, and network devices that interconnect the enterprise network to the Internet. The Internet Edge includes technology necessary to connect telecommuters from the Internet to services in the enterprise. 3 Campus Designs Modular - easily supports growth and change. Scaling the network is eased by adding new modules in lieu of complete redesigns. Resilient - proper high-availability (HA) characteristics result in near-100% uptime. Flexible - change in business is a guarantee for any enterprise. These changes drive campus network requirements to adapt quickly. 4 Multilayer Switches in Campus Networks Hardware-based routing .
