Summary
 Hierarchical Design model addresses performance,
scalability, maintainability & manageability issues.
 Traffic Analysis is used to monitor network
performance.
 Hierarchical Design Model is composed of 3 layers:
Access
Distribution
Core
 Switches selected for each layer must meet the needs
of each hierarchical layer as well as the needs of the
business.
