2. Today’s Internet Today’s Internet is not designed for the: * work of millions of users * existing traffic jam * use of multimedia and * interaction in a real time Today’s Internet does not provide: * reliable performance for the end users * stimulation for cooperation on development of the new network capabilities * network environment for testing of the new network technologies But it is the only one that can ensure: * explosive growth and * convergence of the information work, mass media and human cooperation * development of revolutionary network applications

3. BILL CLINTON BILL CLINTON – 100 millions of dollars each year in the time period of 3 years UCAID (1998.) UCAID (1998.) – parent organisation of the I2 project - - - - COOPERATION COOPERATION – corporation partners (Cisco Systems, Nortel Networks, Qwest Communi- cations, Juniper Networks) => ABILENE - ABILENE ABILENE – bandwith about 2,4 Gbps with the plans for upgrading to 9,6 Gbps by the end of 2003. NSF (1995.) NSF (1995.) – Cooperation Agreement (MCI WorldCom) => very high speed Backbone Network Service (vBNS) - - vBNS vBNS – bandwith about 2,4 Gbps with the plans of future upgrading ABILENE and vBNS ensured new network capabilities: * High bandwith * Low latency * Low latency variation (jitter) * Multicasting => HIGH-PERFORMANCE NETWORK ENVIRONMENT - INTERNET 2 Internet 2

5. 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 distributed sites to collaborate in a real time in a shared, simulated, hybrid environment as if they were in 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 !

7. Potential applications and the future of Tele-immersion Office of the futureFuture TI surgical trainings => PROTOTYPE APPLICATION => NSF ITR dotation (2001.): $ 2,65 mil. => Cooperation (UNC, Upenn, PSC) on development of a high-quality 3D tele- immersion in a real time on a greater distances (2000. - East Coast of the USA) => GOAL ACHIEVED: 15 th Super Computing 2002 conference (December 2002.) - the boost in computer power = image an entire room in a real time - acquisition, processing and display in 3 remote sites = the first “Network computer” Business life, E-commerce, scientific and research cooperation, education, arts,…
