ABILENE and vBNS ensured new network capabilities:

* High bandwith* Low latency* Low latency variation (jitter)* Multicasting

What is Tele-immersion?What is Tele-immersion?Def. (Jaron Lanier): TELE-IMMERSION is a new medium of human interaction that creates illusion that the user is in the same physical space like the other participants, although in reality other participants are thousands of miles away. This is a new telecommunication medium that combines aspects of virtual reality with 3D videoconferencing.

Def. (Internet2 project): TELE-IMMERSION enables users at geographically distributedsites to collaborate in a real time in a shared, simulated, hybrid environment as if they werein the same physical room.

It is the ultimate synthesis of media technologies:

* 3D environment scanning - 3D reconstruction based on display* projective and display technologies* tracking technologies* audio technologies* robotics and haptics

and powerful networking (high bandwith, low latency i low latency variation) => ONE OF THE MOST CHALLENGING NETWORK APPLICATION !
