Internet2 Areas of Work
  • Advanced Applications
  • Middleware
  • Network Engineering
  • End to End Performance
  • Advanced Network Infrastructure
  • Partnerships and Outreach

23
The new science e-science
  • Science used to about test tubes, wet labs and
    big instruments
  • But increasingly science is moving to networks
    and computers
  • Science is now longer bound by bricks and mortar
    or geography
  • Recognition that more and more science is network
    and computationally based
  • A problem is broken into many small tasks then
    distributed to thousands of PCs world wide when
    PCs are not busy they work on the distributed
    computation endpoints work on solving a problem
    or a part of it

24
Attributes of Advanced Apps
  • Provide qualitative and quantitative improvements
    in how we conduct research and engage in teaching
    and learning
  • Common attributes
  • Remote instrumentation and interactive
    collaboration
  • Distributed data storage and data mining
  • Large-scale, multi-site computation
  • Real-time access to remote resources
  • Dynamic data visualization
  • Shared virtual reality
  • Cover a broad range of fields and activities
  • advanced apps leverage technology and implement
    capabilities not possible without Abilene

25
Remote Instrumentation and Data Analysis
  • Large scientific projects increasingly draw on
    resources from many countries.
  • Scientists can use high-performance networks for
    remote instrument control and to pool computing
    resources for data analysis, improving ease of
    use and lowering costs.
  • Latency, Loss and Jitter (network quality) are
    more important than pure bandwidth
  • Instrumentation controllable without local
    intervention
  • Individual sites will have multiple data sources
    streaming data that will interact with the remote
    instrument
  • Data will be made available both in real time
    and via storage

26
Remote Electron Microscope
Application Examples Remote Instrumentation
  • Provide wider access to limited resource
  • Multiple locations can leverage investment in
    hardware
  • Improves teaching and learning
  • Provide access to tools that are prohibitively
    expensive, fragile, etc. for general use through
    safeguards in the interface
  • Create a dynamic resource
  • Share equipment
  • Dynamically analyze data with remote collaborators

27
Wired EMS Vehicles
Application Examples Remote Instrumentation
  • Using high quality video and physiological
    telemetry
  • Creating adequate level of situational awareness

    personnel onboard the ambulance
  • Transit time is no longer wasted
  • Sensors transmit information back to central base
  • Combining multiple technologies Advanced
    Networking (at base stations), Mobile WiFi
    (802.11a/b/g, military radio-data, etc.)

28
Science and Engineering
  • Astronomers trying to collect data about star
    from many different earth based antennae
  • Data analysis 24x7 send data at 1Gb/s from over
    20 antennae located around the globe
  • VLBI very long baseline interferometry

An international collaboration (US, Australia,
U.K., Canada, Chile, Argentina, Brazil)
Mauna Kea, Hawaii, USA
Cerro Pachon, Chile
  • Observers do not need to have physical contact
    with the equipment
  • Data collection equipment is located in extreme
    environments
  • Collaborators are spread across the globe

30
Astronomy- eVLBI
Application Examples Science and Engineering
  • Electronic Very Long Baseline Interferometry
  • Multiple antennae from multiple physical
    locations
  • Each antennae transmits data to a central
    correlation facility
  • Previously recorded data to tape goal is to send
    all data dynamically over Abilene
  • Data rates are projected at 1Gb/s per telescope
  • Successfully tested between points (in the United
    States) at rates of 800 Mb/s

Interesting Successfully ran 788 Mbps sustained
test between sites in U.S. Working on prototype
experiment to test their ability to run data to
Europe and Japan.
31
HENP
Application Examples Science and Engineering
  • High Energy and Nuclear Physics
  • Physicists has traditionally been one of the
    power users of all networks
  • Generating Terabytes of data (1,000,000,000,000
    or 1x1012) per experiment from the CERN lab in
    Switzerland
  • They are working on bulk data transfers that are
    extremely resistant to data loss
  • VRVS, a video conferencing tool, was developed by
    the physics community

Interesting HENP is working on several protocols
that take advantage of parallel streams and good
neighbor practices (passive QOS)
32
Grids
  • Grids enable the new science
  • Original motivation, and support, from high-end
    science and engineering
  • Enable communities (virtual organizations) to
    share resources as they pursue common goals
  • New applications enabled by the coordinated use
    of geographically distributed resources
  • E.g., distributed collaboration, data access and
    analysis, distributed computing, instrumentation
  • Persistent infrastructure for large scale
    computing problems
  • Using distributed computing resources of
    schools, universities and research centers

33
AccessGrid
Application Examples Digital Video and
Collaboration
  • Multiple video streams are broadcast
    simultaneously (via TCP/IP multicast)
  • Talking head video is supported by
    environmental streams from multiple cameras
  • Video can be used for collaboration and as a way
    to store data
  • Vendors are beginning to commercialize the
    technology

Interesting Currently over 125 AccessGrid nodes
are online around the world, including an InSors
node at the University of Michigan Business School
