Telepresence and Metcalfe’s Law

3. Network Infrastructure Considerations in the World of Telepresence
Centralized MCUs made sense when the video world used ISDN
Aggregate PRIs was the most cost effective network design
The move to IP changed all this
Distributed architecture methodology
Put the right sized MCUs throughout the organization and link them dynamically
This is even more true for high bandwidth applications like telepresence

6. Telepresence: Metcalfe’s Law: Videoconferencing done right
An uncompromised experience
Metcalfe’s Law:
The magic of interconnections: connect any number "n" of machines - whether computers, phones or even cars – and you get "n" squared potential value
Think of phones without networks or cars without roads
Conversely, imagine the benefits of linking the value of telepresence systems to the existing millions of room videoconferencing systems or to the hundreds of million desktops deployed today

7. Allow the MCU to mix different devices into the telepresence conference
The quality compromise can be offset by the value of expanded participation
