  • ICFA and Global Networks for Collaborative ScienceNational and International Networks, with rapidly increasing capacity and end-to-end capability are essential, forThe daily conduct of collaborative work in both experiment and theoryExperiment development & construction on a global scaleGrid systems supporting analysis involving physicists in all world regions The conception, design and implementation of next generation facilities as global networksCollaborations on this scale would never have been attempted, if they could not rely on excellent networks

  • Challenges of Next Generation Science in the Information AgeFlagship Applications High Energy & Nuclear Physics, AstroPhysics Sky Surveys: TByte to PByte block transfers at 1-10+ GbpsFusion Energy: Time Critical Burst-Data Distribution; Distributed Plasma Simulations, Visualization, Analysis eVLBI: Many (quasi-) real time data streams at 1-10 Gbps BioInformatics, Clinical Imaging: GByte images on demandAdvanced integrated Grid applications rely on reliable, high performance operation of our LANs and WANsAnalysis Challenge: Provide results with rapid turnaround, over networks of varying capability in different world regionsPetabytes of complex data explored and analyzed by 100s-1000s of globally dispersed scientists, in 10s-100s of teams

  • Huygens Space Probe Lands on Titan - Monitored by 17 telescopes in Au, Jp, CN, USIn October 1997, the Cassini spacecraft left Earth to travel to SaturnOn Christmas day 2004, the Huygens probe separated from Cassini On 14 January 2005 it started its descent through the dense (methane, nitrogen) atmosphere of Titan (speculated to be similar to that of Earth billions of years ago)The signals sent back from Huygens to Cassini were monitored by 17 telescopes in Australia, China, Japan and the US to accurately position the probe to within a kilometre (Titan is ~1.5 billion kilometres from Earth)Courtesy G. McLaughlin

  • Australian eVLBI data sent over high speed links to the NetherlandsThe data from two of the Australian telescopes were transferred to the Netherlands over the SXTransport and IEEAF links, and CA*net4 using UCLP, and were the first to be received by JIVE (Joint Institute for VLBI in Europe), the correlator siteThe data was transferred at an average rate of 400Mbps (note 1Gbps was available) The data from these two telescopes were reformatted and correlated within hours of the end of the landingThis early correlation allowed calibration of the data processor at JIVE, ready for the data from other telescopes to be addedSignificant intl collaborative effort: 9 OrganizationsG. McLaughlin, D. Riley

  • ICFA Standing Committee on Interregional Connectivity (SCIC)Created in July 1998 in Vancouver ; Following ICFA-NTFCHARGE: Make recommendations to ICFA concerning the connectivity between the Americas, Asia and Europe As part of the process of developing these recommendations, the committee should Monitor traffic on the worlds networks Keep track of technology developmentsPeriodically review forecasts of future bandwidth needs, and Provide early warning of potential problemsCreate subcommittees as needed to meet the chargeRepresentatives: Major labs, ECFA, ACFA, North and South American UsersChair of the committee reports to ICFA twice per year

  • SCIC in 2004-2005 http://cern.ch/icfa-scicThree 2005 Reports, Presented to ICFA Today Main Report: Networking for HENP [H. Newman et al.]Includes Updates on the Digital Divide, World Network Status; Brief updates on Monitoring and Advanced Technologies [*]18 Appendices: A World Network Overview Status and Plans for the Next Few Years of Natl & Regional Networks, and Optical Network Initiatives Monitoring Working Group Report [L. Cottrell] Also See: SCIC Digital Divide Report [A. Santoro et al.] SCIC 2004 Digital Divide in Russia Report [V. Ilyin]TERENA (www.terena.nl) 2004 Compendium

  • SCIC Main Conclusion for 2002-5The disparity among regions in HENP could increase even more sharply, as we learn to use advanced networks effectively, and we develop dynamic Grid systems in the most favored regions We must therefore take action, and work to Close the Digital DivideTo make Scientists in All World Regions Full Partners in the Process of Frontier Discoveries This is essential for the health of our global experimental collaborations, for our field, and for international collaboration in many fields of science.

It proposed to ICFA that these issues, as they affect our field, be brought to our community for discussion. This led to ICFAs approval, in July 2003, of the Digital Divide and HEP Grid Workshop. Review of R&E Networks; Major Grid Projects Perspectives on Digital Divide Issues by Major HEP Experiments, Regional Representatives Focus on Digital Divide Issues in Latin America; Relate to Problems in Other Regions

    International ICFA Workshop on HEP Networking, Grids and Digital Divide Issues for Global e-Science

    Workshop Goals Review the current status, progress and barriers to effective use of major national, continental and transoceanic networksReview progress, strengthen opportunities for collaboration, and explore the means to deal with key issues in Grid computing and Grid-enabled data analysis, for high energy physics and other fields of data intensive scienceExchange information and ideas, and formulate plans to develop solutions to specific problems related to the Digital Divide, with a focus on the Asia Pacific region, as well as Latin America, Russia and Africa Continue to advance a broad program of work on reducing or eliminating the Digital Divide, and ensuring global collaboration, as related to all of the above aspects.
