Critical Features
Multiple servers – global distribution
Geo location built into Client, levered
In STUN/TURN
Client and Signaling server behave
Intelligently – known bandwidth
Alice
capability – signaling adaptation gives
HD effect @300 kps
Client uses “active thumbnails” to give
initiator
user control and minimize bandwidth
Pure mesh to 10 pax – limit at client
processor
Optimizes bandwidth with layout
freedom (at client)
