Hierarchical Campus Designs
Hierarchical campus design divides the network into discrete layers. Each layer provides specific functions that define its role within the overall network, which facilitates scalability and performance:
- Access layer: Provides local and remote user access.
- Distribution layer: Controls the flow of data between the access and core layers.
- Core layer: Acts as the high-speed redundant backbone.
Three-Tier hierarchical campus network design:
Two-Tier Campus Design
The core often collapsed into the distribution layer for a two-tier design in smaller network
This design solves two major design needs:
- Connects end-user devices.
- Connects the switches with a reasonable number of cables and switch ports by
connecting all access switches to two distribution switches
SOHO Routers:
For very small networks and home networks SOHO (Small Office Home Office) , all three tiers can be seen in one device, such as the Wireless broadband router
