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
