Collapsed Backbone

Network backbones are distributed or collapsed. Traditional LANs connect via distributed backbone cables. Collapsed backbones use high-speed backplane switches to connect virtual Point-to-Point (PPP) LAN networks.

Collapsed backbone advantages include:

• Requires fewer devices
  
• Eliminates backbone cabling installation costs
  
• Provides scaled station bandwidth
  
• Provides tightly centralized equipment administration
  

Collapsed backbone disadvantages include:

• Requires extra cabling
  

• Requires more expensive devices
• Limited distance capabilities
• Redundancy
  
• Not feasible for multiple buildings
