The document discusses a hierarchical network design model for small and medium-sized businesses. It describes how the hierarchical model supports voice, video, and data needs through converged networking. The model uses different switches at three layers - access, distribution, and core - to address performance, scalability, manageability and other issues. Key considerations in matching switches to the appropriate layer include features, applications and business needs.

10. 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.
