The LAN is the networking infrastructure that provides access to network communication services and resources for end users and devices spread over a single floor or building. You create a campus network by interconnecting a group of LANs that are spread over a local geographic area. Campus network design concepts include small networks that use a single LAN switch, up to very large networks with thousands of connections.
The campus wired LAN enables communications between devices in a building or group of buildings, as well as interconnection to the WAN and Internet edge at the network core.
Specifically, this design provides a network foundation and services that enable :
* Tiered LAN connectivity.
* Wired network access for employees.
* IP Multicast for efficient data distribution.
* Wired infrastructure ready for multimedia services.
