Network Infrastructure in the World of Telepresence

2. Network Infrastructure Considerations in the World of Telepresence 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

4. IP Network Site B Site A MCU Site C • Centralized MCU approach • 3 segment telepresence system • Loads the WAN network

5. IP Network Site B Site A MCU MCU Site C • Distributed Architecture • Put the intelligence in the network • Minimizes use of expensive WAN bandwidth MCU

6. 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

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