STAR TAP Science Technology and Research Transit Access Point University of Illinois at Chicago

What is STAR TAP (vision)? • Persistent 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 G 7 GIBN initiative University of Illinois at Chicago

What is STAR TAP (details)? • STAR TAP anchors v. BNS 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 Giga. Po. P • 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 Internet 2 • STAR TAP is part of the USA Next Generation Internet (NGI) Initiative • STAR TAP (NGIX) connects USA agency networks like the v. BNS, ESnet, NREN, and DREN to other countries and networks • Internet 2/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 / Qo. S 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 University of Illinois at Chicago
