  1. Tele-Immersion and High-Speed Networking Maxine Brown Associate Director, Electronic Visualization Laboratory March 15, 1999

  2. Electronic Visualization LaboratoryWhat is EVL? • 25 years at UIC • Joint program between UIC Computer Science and Art & Design departments • 2 directors and 12 associated faculty • 10 staff • 100 graduate students (24 supported) • Collaborations with • NCSA Alliance • Argonne National Laboratory

  3. Electronic Visualization Laboratory CAVE Research and Development 1992—Prototype CAVE 1993—10’x10’x10’ CAVE 1994—SIGGRAPH VROOM 1995—I-WAY at SC’95 1997—100 CAVES and derivatives worldwide 1997-8—NSF funding for tele-immersion, new desktop VR devices, STAR TAP, NCSA Alliance

  4. 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 delivery www.evl.uic.edu/cavern www.ncsa.uiuc.edu/VR/cavernus

  6. Supercomputing ‘95 I-WAY • EVL/Argonne/NCSA planned and built I-WAY for Supercomputing ‘95 • Prototyped on MREN • First large-scale agency interoperability test of IP over ATM: vBNS, AAI, ESnet, ATDnet, CalREN, NREN, MREN, MAGIC, CA*NET • 33 Academic, National Lab and Industry institutions; 17 sites; 61 projects • First Tele-Immersion experiments

  7. I-WAY — Grid v1.0Blueprint for a New Computing InfrastructureI. Foster, C. Kesselman (Eds),Morgan Kaufmann, 1999 • ISBN 1-55860-475-8 • 22 chapters by expert authors including Andrew Chien, Jack Dongarra, Tom DeFanti, Andrew Grimshaw, Roch Guerin, Ken Kennedy, Paul Messina, Cliff Neuman, Jon Postel, Larry Smarr, Rick Stevens, and many others “A source book for the history of the future” -- Vint Cerf http://www.mkp.com/grids

  9. STAR TAPScience Technology and Research Transit Access Point

  10. What is STAR TAP (vision)? • Persistentinterconnection 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

  11. 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

  12. 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)

  14. SC’98 iGrid: The International GridResearch Demonstrations • 22 demonstrations that featured technical innovations and application advancements requiring high-speed networks, with emphasis on distributed computing, tele-immersion, large datasets, remote instrumentation, and collaboration • 10 countries: Australia, Canada, Germany, Japan, Netherlands, Russia, Singapore, Switzerland, Taiwan, USA www.startap.net/igrid/

  21. 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

  22. 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

  23. 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
