Internet
End to end principle:
• Gateway are invisible to application
• Naming is uniform
L2 independence:
• Evolution, universality
• Abstract L2 characteristics
Cost reduction:
• Interconnection
• services deployment
• Management:
• Objects
• Networks
Durability
Internet has been designed over an unlimited bandwidth model.
