Confusion: Open Internet

Applications (OSI layers 5-7) Content (OSI layer 7) TCP (OSI 4 transport) IP (OSI 3 network) LAN-link (OSI 1 physical, OSI 2 data link ) Skype

• ffering VoIP

Cox offering priority service ?? Cox offering VoIP using priority service What is a “specialized service”?

Competition reliant on availability

• f QoS

Confusion: Wireless Networks

Applications (OSI layers 5-7) Content (OSI layer 7) TCP (OSI 4 transport) IP (OSI 3 network) LAN-link (OSI 1 physical, OSI 2 data link ) What is different about wireless networks?

Confusion: Universal Service

Applications (OSI layers 5-7) Content (OSI layer 7) TCP (OSI 4 transport) IP (OSI 3 network) LAN-link (OSI 1 physical, OSI 2 data link ) Funds subsidize infrastructure Phone service is assessed What should be assessed? What should be subsidized? What is broadband?

Confusion: Video Service

Applications (OSI layers 5-7) Content (OSI layer 7) TCP (OSI 4 transport) IP (OSI 3 network) LAN-link (OSI 1 physical, OSI 2 data link ) Video over the top How to treat

providers? How to guarantee right to use any device?

Layering: barriers to entry

Applications (OSI layers 5-7) Content (OSI layer 7) TCP (OSI 4 transport) IP (OSI 3 network) LAN-link (OSI 1 physical, OSI 2 data link ) Many providers due to low barrier-to-entry Few providers due to high barrier-to-entry

Require open interface to lower layer QoS

Layering: Wireless Networks

Applications (OSI layers 5-7) Content (OSI layer 7) TCP (OSI 4 transport) IP (OSI 3 network) LAN-link (OSI 1 physical, OSI 2 data link ) Wireless networks are different here not here What is different about wireless networks?

Layering: Universal Service

Applications (OSI layers 5-7) Content (OSI layer 7) TCP (OSI 4 transport) IP (OSI 3 network) LAN-link (OSI 1 physical, OSI 2 data link ) Phone service is assessed What should be assessed? What should be subsidized? What is broadband?

Funds subsidize infrastructure Assess and subsidize network infrastructure

Layering: Video Service
