Chapter 22 - Enterprise Network Architecture

access layer

The network layer that gives endpoints and users direct access to the network.

building block or network block or place in the network (PIN)

a distinct place in the network (PIN) such as the campus end-user/endpoint block, the WNA edge block, the internet edge bloc, or the network service block. the components of each building lock are the access layer, the districution layer, and/or the core (backbone) layer. also known as a network block or place in the network (PIN).

core layer

the netowrk layer, also knwon as the backbone, that provides high-speed connectivity between districution layers in large environments.

distribution layer

The network layer that provides an aggregation point for the access layer and acts as a services and control boundary between the access layer and the core layer.
