• 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

• Telepresence:– 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

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