HENP Major Links Bandwidth Roadmap (Scenario)
in Gbps
Continuing the Trend 1000 Times Bandwidth
Growth Per DecadeWe are Rapidly Learning to Use
and Share Multi-Gbps Networks

HENP Lambda GridsFibers for Physics
  • Problem Extract Small Data Subsets of 1 to 100
    Terabytes from 1 to 1000 Petabyte Data Stores
  • Survivability of the HENP Global Grid System,
    with hundreds of such transactions per day
    (circa 2007)requires that each transaction be
    completed in a relatively short time.
  • Example Take 800 secs to complete the
    transaction. Then
  • Transaction Size (TB) Net
    Throughput (Gbps)
  • 1
    10
  • 10
    100
  • 100
    1000 (Capacity of
    Fiber
    Today)
  • Summary Providing Switching of 10 Gbps
    wavelengthswithin 3-5 years and Terabit
    Switching within 5-8 yearswould enable
    Petascale Grids with Terabyte transactions,as
    required to fully realize the discovery potential
    of major HENP programs, as well as other
    data-intensive fields.

IEPM PingER Deployment
Monitoring Sites
  • Measurements from
  • 34 monitors in 14 countries
  • Over 790 remote hosts 3600 monitor-remote site
    pairs
  • Recently added 23 Sites in 17Countries, due to
    ICTP Collaboration
  • Reports on RTT, loss, reachability, jitter,
    reorders, duplicates
  • Measurements go 6ack to Jan-95
  • 79 Countries Monitored
  • Contain gt 80 of world population
  • 99 of online users of the Internet
  • Mainly AR sites

History Loss Quality
(Cottrell)
  • Fewer sites have very poor to dreadful
    performance
  • More have good performance (lt 1 Loss)

Work on the Digital DivideSeveral Perspectives
  • Identify Help Solve Technical Problems
    Natl, Regional, Last 10/1/0.1 km
  • Inter-Regional Proposals (Example Brazil)
  • US NSF Proposal (10/2002) possible EU LIS
    Proposal
  • Work on Policies and/or Pricing pk, in, br, cn,
    SE Europe,
  • E.g. RoEduNet (2-6 to 34 Mbps) Pricing not so
    differentfrom US-CERN price in 2002 for a few
    Gbps
  • Find Ways to work with vendors, NRENs, and/or
    Govts
  • Use Model Cases Installation of new advanced
    fiber infrastructures Convince Neighboring
    Countries
  • Poland (to 5k km Fiber) Slovakia Ireland
  • Exploit One-off Solutions E.g. extend the SILK
    Project (DESY/FSU satellite links) to a SE
    European site
  • Work with other organizations Terena, Internet2,
    AMPATH, IEEAF, UN, etc. to help with technical
    and/or political solns

Digital Divide WG Activities
  • Questionnaire Distributed to the HENP Lab
    Directors and the Major Collaboration
    Managements
  • Plan on Project to Build HENP World Network
    Map Updated and Maintained on a Web Site,
    Backed by Database
  • Systematize and Track Needs and Status
  • Information Link Bandwidths, Utilization,
    Quality, Pricing, Local Infrastructure, Last
    Mile Problems, Vendors, etc.
  • Identify Urgent Cases Focus on Opportunities to
    Help
  • First ICFA SCIC Workshop Focus on the Digital
    Divide
  • Target Date February 2004 in Rio de Janeiro
    (LISHEP)
  • Organization Meeting July 2003
  • Plan Statement at the WSIS, Geneva (December
    2003)
  • Install and Leave Behind a Good Network
  • Then 1 (to 2) Workshops Per Year, at Sites that
    Need Help

15
We Must Close the Digital Divide
  • Goal To Make Scientists from All World
    Regions Full Partners in the Process of
    Search and Discovery
  • What ICFA and the HENP Community Can Do
  • Help identify and highlight specific needs (to
    Work On)
  • Policy problems Last Mile problems etc.
  • Spread the message ICFA SCIC is there to help
    Coordinatewith AMPATH, IEEAF, APAN, Terena,
    Internet2, etc.
  • Encourage Joint programs such as in DESYs Silk
    project Japanese links to SE Asia and China
    AMPATH to So. America
  • NSF LIS Proposals US and EU to South America
  • Make direct contacts, arrange discussions with
    govt officials
  • ICFA SCIC is prepared to participate
  • Help Start, or Get Support for Workshops on
    Networks ( Grids)
  • Discuss Create opportunities
  • Encourage, help form funded programs
  • Help form Regional support training groups
    (requires funding)

16
Cultivate and promote practical solutions to
delivering scalable, universally available and
equitable access to suitable bandwidth and
necessary network resources in support of
research and education collaborations.

Networks, Grids and HENP
  • Current generation of 2.5-10 Gbps network
    backbones arrived in the last 15 Months in the
    US, Europe and Japan
  • Major transoceanic links also at 2.5 - 10 Gbps
    in 2003
  • Capability Increased 4 Times, i.e. 2-3 Times
    Moores
  • Reliable high End-to-end Performance of network
    applications(large file transfers Grids) is
    required. Achieving this requires
  • End-to-end monitoring a coherent approach
  • Getting high performance (TCP) toolkits in
    users hands
  • Digital Divide Network improvements are
    especially needed in SE Europe, So. America SE
    Asia, and Africa
  • Key Examples India, Pakistan, China Brazil
    Romania
  • Removing Regional, Last Mile Bottlenecks and
    Compromises in Network Quality are now On the
    critical path, in all world regions
  • Work in Concert with APAN, Internet2, Terena,
    AMPATH DataTAG, the Grid projects and the
    Global Grid Forum
