Switched LAN Architecture
 Hirarchical Network Design |
|
Benefits of a Hirarchical Network
- Scalability
- Hierarchical netowrk can be expanded easily
- Redundancy
- Redundancy at the core and distribution level ensure path availability
- Performance
- Link aggregation between levels and high-performance core and distribution level switches allow for near wire-speed throughout the network
- Security
- Port security at the access level and policies at the distribution level make the network more secure
- Manageability
- Consistency between switches at each level makes management more simple
- Maintainablity
- The modularity af hierarchical design allows for the network to scale without becoming overly complicated

Matching Switches to Specific LAN Functions
 Locate heavy traffic servers close to the users |
- Bandwidth aggregation and switch forwarding rates are important factors to consider when attempting to eliminate bottlenecks
- Switches selected for data centers should be higher performing switches than the switches you would find in the wiring closets at the access layer
