| BN | "Backbone Network" a large network to which many networks within an organization are connected; usually is a network that interconnects all networks on a single site, but can be larger |
| core layer | the central part of a network that provides access to the distribution layer; often a very fast BN ("Backbone Network") that runs through the center of a campus or office complex |

| layer-3 switch | functions similarly to layer-2 switches, but switch messages on the basis of their network layer address (usually IP address) |
| multiprotocol router | can understand several different network layer protocols |
| routed backbone | move packets along the backbone on the basis of their network layer address; sometimes called "subnetted backbones" or "hierarchical backbones" and are most commonly used to connect different buildings within the same campus network |
| router | a device that connects two similar networks having the same network protocol; also chooses the best route between two networks when there are multiple paths between them |
