An enterprise campus is often defined as 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. It might span a single floor, building or even a large group of buildings spread over an extended geographic area. Some networks will have a single campus that also acts as the core or backbone of the network and provide interconnectivity between other portions of the overall network. The campus core often interconnects to the campus access, the data center and WAN portions of the network. A large enterprise might have multiple campus sites distributed worldwide with each providing both end user access and local backbone connectivity.
Layers of the Typical Campus Hierarchy
The access layer is the first tier or edge of the campus. It is the place where end devices (PCs, printers, cameras, and the like) attach to the wired portion of the campus network. It is also the place where devices that extend the network out one more level are attached—IP phones and wireless access points (APs) being the prime two key examples of devices that extend the connectivity out one more layer from the actual campus access switch.
The distribution layer is the aggregation point for all of the access switches and acts as an integral member of the access-distribution block providing connectivity and policy services for traffic flows within the access-distribution block. It is also an element in the core of the network and participates in the core routing design. Its third role is to provide the aggregation, policy control and isolation demarcation point between the campus distribution building block and the rest of the network.
The campus core is the backbone that glues together all the elements of the campus architecture. It is that part of the network that provides for connectivity between end devices, computing, and data storage services located within the data center—and other areas and services within the network. It serves as the aggregator for all of the other campus blocks and ties together the campus with the rest of the network.
