  1. Guinness Book of Records 2004 117MBytes/s CA to NL 3GBytes/s from SC03 1st N. American web site China on Internet BaBar data exceeds PB, Largest database in world BaBar takes 1st data

  2. Linear x axis

  3. Bandwidth of a 747 • Fully load 747 with 40GB DLT tapes and fly from California to Geneva in 10 hours is ~ 2-4 Tbits/s. However the latency is closer to 2 weeks (30 time longer or closer to 6-12 Gbits/s), by the time one has removed the tape from the silo, packaged it up, had it picked up and delivered to airport, flown, go through customs, delivered to lab, unpackaged, inserted in silo, read etc. Also using the network people power required (typically 2 people at sending Lab organizing etc.) is dramatically reduced, it is automateable, errors are dealt wit automatically (dealing with mis-aligned tape heads, tape errors etc. is a major headache). It also provides the remote researcher with the data within a day of when it was recorded rather than 2 weeks, which makes the researcher feel more part of the experiment.

  4. Media 1CD=700MBytes 1DVD=4.7GBytes 2 ins SLAC Objectivity database = 1 PByte ~ 1 mile of CDs! or 5 Empire State buildings end to end A stack of 38 CDs or DVDs = 2 inches = 26GBytes (CD) = 180GBytes (DVD) 1 mile of CDs = 0.84PB

  5. Library of Congress Holds 10 TBytes At a Gbits/s can transmit in under a day At 10Gbits/s can transmit in ~ 2 hours

  6. Bandwidth needed for applications • Speed Functionality • 100kbps Fast Internet & email, games, voice • 1Mbps Music • 1.5Mbps Broadcast-quality MPEG-II video • 10Mbps One (limited) HDTV channel & two basic channels • 50Mbps Full HDTV support; off-site computing storage • Source: Gartner Dataquest, June 2002

  7. Example of use for Medicine • Radiation oncology for each patient visit (e.g. a mammogram, 2 views, 2 breasts, 4Kx4Kx16bits / picture) between 100 and 500MBytes of data are collected • 3M women with mammograms in UK alone, 400TBytes/year for UK • Today often saved as film and diskettes. • Costs savings: e.g. in storage space, and labor to keep it organized, automated digital library can scale to larger numbers of patients • Better patient care: ability to share images in real-time with distributed experts, • Mine information for better clues on treatments

  8. Digital Divide • SLAC/HENP/DoE provided first permanent Internet connection to mainland China, 1994 • Opened up China, politically, commerce etc. • SLAC currently provides the most widespread measurements of Internet performance to developing countries

  9. Bringing the Internet to China • Needed to support US collaborators using new accelerator in Beijing • Installed 64kbps satellite link from SLAC to Beijing • Started in April 1991 • Final connection May 1994 • First web page in China

  10. First US Web Site Dec 12, 1991 Early web page “Killer application” online access to HENP library databases without requiring an account
