SCIC in the WSIS Stocktaking Report(July 2005): http://www.itu.int/wsis • The SCIC, founded in 1998 by ICFA, is listed in Section 7.8, on E-science: “ The International Committee on Future Accelerators: Standing Committee on Inter-regional Connectivity monitors the world’sresearch and education networks, tracking requirements and deals especially with digital divide issues. Its main goal is to foster global scientific collaboration, so enabling scientists around the world to participate in frontier scientific discoveries.” [No other initiative cited is quoted as working towards equality in scientific research. Such equality is a foundation of HEP’s collaborations.] • We focus on cost-effective technology solutions that bring communities to a point where they can collaborate effectively; and create a “sustainable process of innovation” • For Africa this requires a modern optical fiber infrastructure
The Global Lambda Integrated Facility for Research and Education (GLIF) • Architecting an international LambdaGrid infrastructure • Grid applications “ride” on dynamically configured networks based on optical wavelengths. GLORIAD Link Inaugurated 9/4/05 Interconnecting Nat’l Lambda Rail (US)CANARIE (CA)JGN2 (Japan)GEANT2 in EuropeCLARA in Latin Am. … 10 Gbps Links Across the Atlantic and Pacific are a New Reality

SCIC Main Conclusion for 2004Setting the Tone for 2005 • The disparity among regions could increase even more sharply, as we deploy and learn to use advanced networks effectively, and develop dynamic Grid systems in the “most favored” regions • We must therefore take action, to Close the Digital Divide • To make physicists from all world regions full partners in their Experiments; and in the process of scientific discovery • This is essential for the health of our global experimental collaborations, our plans for future projects, and our field.
New Focus on AFRICAMany Systemic Issues:Lack of energy,infrastructure. Lack of expertiseProblems of Disease Political unrestPricing Import duties & policies Corruption 800M People, 1.4% with Internet Access: More than an order of magnitude lower than in Europe (35%) & North America (70%) M. Jensen
Africa Coverage • We now cover most (31) countries with many tertiary education centers (83% of the population) • Recently added monitoring site in So. Africa (TENET)
Satellites vs Terrestrial • Terrestrial links via SAT3 & SEAMEWE (Mediterranean & Red Sea) • Terrestrial not available to all within countries Note: Satellite Links are a Boon to the Region, but typical unit bandwidth costs are 300-1000X more than Fiber.There is a Continued Need for Fiber Infrastructure
SCIC in 2004-2005http://cern.ch/icfa-scic Three 2005 ReportsFocus on the Digital Divide • Main Report: “Networking for HENP” [H. Newman et al.] • Includes Updates on the Digital Divide, WorldNetwork Status; Brief updates on Monitoring and Advanced Technologies • 18 Appendices: A World Network Overview Status and Plans for the Next Few Years of Nat’l & Regional Networks, and Optical Network Initiatives • Monitoring Working Group Report [L. Cottrell] Also See: • SCIC 2003 Digital Divide Report [A. Santoro et al.] • TERENA (www.terena.nl) 2004 Compendiumon R&E Networks in Europe
ICFA Report (2005) Update: Main Trends Continue, Some Accelerate • Current generation of 2.5-10 Gbps network backbones and major Int’l links arrived in 2001-5 in US, Europe, Japan; Now Korea and China • Growth: 4 to Hundreds of Times; Much Faster than Moore’s Law • Proliferation of 10G links across the Atlantic & Pacific; Begin use of Multiple 10G Links (e.g. US-CERN) Along Major Paths by Fall 2005 • Tech. Progress Driving Equipment Costs Lower • Commoditization of Gigabit and now 10-Gigabit Ethernet • More than Just Bandwidth is Needed:Grids demand seamless networks, with reliable high performance end-to-end, managed to enforce fair-sharing among “priority” tasks • Emergence of the “Hybrid” Network Model: UltraLight, GLIF • Some regions (US, Canada, Europe; Brazil) moving to dark fiber
