Electronic Visualization LaboratoryCAVERN Research and Development
• Tele-immersion will enable users in different locations to
collaborate in a shared, simulated environment as if they
were in the same room—the ultimate synthesis of
networking and media technologies to enhance
collaborative environments
• Tele-immersion applications must combine audio, video,
virtual worlds, simulations, and many other complex
technologies, requiring huge bandwidth, very fast
responses, and guarantees of deliverywww.evl.uic.edu/cavernwww.ncsa.uiuc.edu/VR/cavernus

What is STAR TAP (vision)?
• PersistentPersistent interconnection point and anchor for advanced (high-performance) networking initiatives of the USA and international partners
• Enabler for collaborative development of next-generation Internet applications
• A capability born out of frustrations of past I-WAY experience and the hopes of the G7 GIBN initiative
University of Illinois at Chicago
What is STAR TAP (details)?
• STAR TAP anchors vBNS International Connections program
• STAR TAP features a large ATM switching facility run by Ameritech Advanced Data Services (AADS) with the same physical equipment as the MREN Chicago GigaPoP
• STAR TAP’s goal is to develop the teams, tools, system software, documentation, and human interface models to enable international-scale, multi-site collaborations
University of Illinois at Chicago
STAR TAP, NGI, and Internet2
• STAR TAP is part of the USA Next Generation Internet (NGI) Initiative
• STAR TAP (NGIX) connects USA agency networks like the vBNS, ESnet, NREN, and DREN to other countries and networks
• Internet2/UCAID/Abilene peer at STAR TAP• Experimental networking is encouraged (e.g.,
Wave Division Multiplexing with CA*NET 3, NU, NCSA, IU, UIC)
University of Illinois at Chicago

International Applications-Level Networking Challenges and Opportunities
• Building relationships – internationalization• Time zones
– Asynchronous collaboration– Annotations and recording
• Network speeds / QoS needs• Speed of light – bandwidth x latency (delay)• Audio – one of the most demanding app’s.• Culture – elitism/equality; industrial partners
University of Illinois at Chicago
International Impact: Five Years From Now
• Distributed computing, simulation, data mining, and instruments will be coupled with tele-immersion over the worldwide Grid; audio, video, gesture and haptics will be integrated with latency tolerant techniques
• Methods for recording, editing, annotating, replaying, and broadcasting tele-immersive sessions will be perfected; avatars will help convey a true sense of tele-presence
University of Illinois at Chicago
International Impact: Five Years From Now
• Tele-immersion is particularly critical for trans-oceanic science and engineering users
• Tele-immersion (CAVERN implementation) is particularly difficult and challenging as distance increases
• Significant participation expected by international researchers via STAR TAP, given support for applications development
