5. IP Network Service Strategies
Facilities Based: (Qwest, Level3, Global Crossing, ATT, WorldCom, Sprint) own their own networks.
Private-line-leasing (Wire One, SAVVIS, Masergy, V-SPAN, PSInet, IVCi) lease but do not own private lines.
Use public Internet: (Virtela, Internap) provide customers with encryption; create VPN with tunneling

6. Overlay vs. Converged Networks
Separate IP network for video
Avoids congestion for data
Limits QoS concerns for voice and video
Avoids internal politics
One network does it all
Maximizes efficiency
One network to deploy, manage, maintain
